  2. Hello all... loading 44 mag and I'm needing some piece of mind with a question that's bugging me....Book says shot out of 8 inch barrel should be 1340 fps, when I shoot out of 18inch Henry big boy.  I get 1560 fps average. I fully understand faster velocity for barrel length. But my question is does it change pressure or is pressure consistent with lead data no matter barrel length?

Cartridge Corner Notes:.300 AAC Blackout


The .300 AAC Blackout (designated as the 300 BLK by the SAAMI[1] and 300 AAC Blackout by the C.I.P.[2]), also known as 7.62×35mm is a carbine cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. Its purpose is to achieve ballistics similar to the 7.62×39mm Soviet cartridge in an AR-15 while using standard AR-15 magazines at their normal capacities. Care should be taken not to use 300 BLK ammunition in a rifle chambered for 7.62×40mm Wilson Tactical.[3]


History


While 5.56×45mm NATO has enjoyed widespread acceptance in military circles, the nature of the missions encountered by some special operations groups often demand a round that provides better performance than that available in the high-energy standard velocity rounds and subsonic performance greater than standard 9mm (the ubiquitous pistol round also commonly used in many SMGs).[4]


To satisfy this need, AAC developed the 300 AAC Blackout in cooperation with Remington Defense—under the direction of AAC's Research and Development Director Robert Silvers and with the support of the company's founder, Kevin Brittingham.[5][6]


Meeting these goals allowed the development team to negate many of the perceived drawbacks inherent to other large caliber cartridges used in the M4. Colt Firearms and other arms makers had previously chambered AR-pattern rifles and carbines in various .30 caliber rounds but encountered problems. In the case of the 7.62×39mm, its relatively severe case angle caused feeding issues unless specially modified AK-47 magazines were used, and even then results were unsatisfactory[citation needed] Modified bolts were also needed owing to its larger case head diameter. Rounds such as the 6.8 SPC and 6.5 Grendel had similar part-interchangeability issues but did allow for the use of the standard M4/M16 30-round magazine albeit with a reduced capacity.[7]



300 AAC Blackout rounds shot from a suppressed M4 Carbine.

Wildcat cartridges such as the .300 Whisper series addressed these issues, but their widespread use in single shot handguns and lack of industry standard cartridge dimension meant that a great number of the popular loads on both the supersonic and subsonic end of the spectrum were less than ideal in the AR pattern weapons. Many of these rounds required an excessively long overall cartridge length that would prohibit feeding in a STANAG magazine while using powder charges that were not compatible with the pressure requirements of the M4 carbine. This was particularly noticeable when using subsonic ammunition in conjunction with a suppressor as short stroking and excessive fouling would occur similar to that which was seen in the earliest variants of the M16 in Vietnam.[8]


By keeping the M4/M16 in mind as the primary host during load development the designers could work up a host of cartridges that not only satisfied the ballistic requirements set forth, but also ensured mechanical reliability with the fewest changes to the weapon itself—with only a simple barrel change necessary for complete conversion.[9]


Robert Silvers, director of research and development for AAC said, "We started development in 2009, but most of the work was done in 2010. A military customer wanted a way to be able to shoot .30-cal. bullets from an M4 platform while using normal bolts and magazines, and without losing the full 30-round capacity of standard magazines. They also wanted a source for ammunition made to their specs. We could not have just used .300-.221 or .300 Whisper because Remington is a SAAMI company, and will only load ammunition that is a SAAMI-standard cartridge. We had to take the .300-221 wildcat concept, determine the final specs for it, and submit it to SAAMI. We did that, and called it the .300 AAC Blackout (.300 BLK)."[10]


300 AAC BLACKOUT was approved by SAAMI on January 17, 2011.


On October 23, 2011, SSG Daniel Horner of the USAMU used 300 AAC Blackout to win his 4th USPSA Multi Gun National Championship.[11]

Reloading Podcast 241 - pistol and rifle loads the same

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering the question, can I use the same load in my carbine/rifle as my handgun?

  1. Michael Meyn via Gmail

    Hello Gentlemen, I am getting ready to start loading for the wife’s BG38. Is there really much advantage to working up a ladder load for a short barreled revolver like the BG38. I ladder load everything else but am not sure if the short barrel will have enough accuracy to make it worth while? Your knowledgeable opinion would be appreciated!

  2. Craig Findlay sent via email
    Question.. 38 special/357 reloading

    Message: I shoot revolvers and lever action with .38 special and .357 magnum... any tips or thoughts on differences/similarities, and thoughts for reloading for both? any tips for one or the other or both? obviously, the barrel lengths have velocity effects, and maybe govern if the powder gets all burned or not... similar question regarding 30 carbine.. my M1 and Blackhawk....

thanks! love the show

  1. Rusty created a poll in RLPG

    Lead Free Barnes bullets in a 6.5CM what would you prefer for hunting mule deer? Lite and fast or heavier and slower. The solid bullets tend to need more velocity to expand properly and also seem to retain their weight better after impact. I am going to load all three options and see what my rifle likes and try to judge the impact energy somehow.

  2. Dave posted in TRRG CASE LUBE... Hornady One Shot or Redding Imperial?

  3. Joey Commesso posted in RLPG

    What's the best book to consult with for loading 45 lc. Lyman, Hornady and nosler aren't very helpful. I don't honestly know where to start. There has to be a load difference from a 45lc pistol and the Winchester cowboy action rifle right ? I'm loading for the rifle only.

Reloading Podcast 240 - More Questions

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering more questions.

  1. Jeff posted in TRRG: Does anybody use 4350 with 150 gr bullets in 308? None of my manuals show this combo. I haven’t loaded much 308 but I’m going to soon. I have a bunch of 4350 and sure wanted to use it.

  2. Mark posted in CB&BC: What lead do YOU use to cast 45-70 bullets?

    The reason I ask, I have been using up my "Hard Ball" / Lyman #2 equivalent, and have been noticing more leading in the barrel than normal. The bullets are sized .002 over bore diameter, and a buddy mentioned that my lead might be too hard for the lower velocity I'm pushing them at.

    Should I switch my 'slower' bullets to a 1:20 or Wheel Weight mix to see if that solves my leading issue?

    1. Rooster Jacket

  3. Hi team,
    I found your show a fortnight ago and I'm having a blast listening to your back catalogue.

    I'm in Australia so my options are limited for what I can own but I have and reload for the following: howas 1500 in rem 223
    Howa 1500SA in 204 Ruger
    Ruger m77 in 6.5x55
    Marlin 1984 in 357
    Silver pigeon O/U

    I reload very manually using a Redding t7 but I treat it like a single. I have a Lyman g6 for measuring powder but also have a uniflow (not that I use it).
    I'm time poor so normally split my reloads into prep and then loading states as it's unlikely I'll be able to do it all in one hit.

    My current workflow is
    Universal decap
    Wet tumble clean
    Resize
    Trim /deburr/ tidy primers (remove crimp if needed)
    Short wet tumble to remove the lube
    Store until ready
    Then prime with a hand primer
    Use the g6 and a funnel to fill 50 rounds - checking with a torch
    Seat projectiles
    Repeat for the next batch of 50
    What's the best reloading workflow to get the most out of a turret and waste less time without compromising?
    Thank you Paul B

Cartridge Corner Notes: .35 Remington

From Wikipedia, the free encyclopedia


The .35 Remington [8.9x49mm] is the only remaining cartridge from Remington's lineup of medium-power rimless cartridges still in commercial production. Introduced in 1906, it was originally chambered for the Remington Model 8 semi-automatic rifle in 1908.

It is also known as 9x49mm Browning and 9mm Don Gonzalo.

History

Over the years, the .35 Remington has been chambered in a variety of rifles by most firearms manufacturers, and continues in popularity today in the Marlin Model 336 lever-action. It is also a popular cartridge for single-shot hunting pistols like the Thompson/Center Contender and the Remington XP-100. For hunters looking for a good woods gun, (i.e., a medium power rifle with moderate recoil, for short to medium ranges) the .35 Remington is popular, taking second place to the .30-30 Winchester. It has a small but loyal following in the northeast and areas of the southern United States.

The cartridge uses a medium to heavy bullet and has moderate recoil based on a moderate pressure level of 33,500 CUP as set by SAAMI. The normal factory load consists of a 200 grain round-nosed bullet with a muzzle velocity of 2080 feet per second. This 200 grain bullet is nearly 18% heavier than the .30-30's 170 grain bullet, and has a 16% larger frontal area. This gives it a substantial increase in power over the .30-30, especially when used on larger game species.

Remington helped promote the advantage in power that the .35 Remington had over the .30-30 through a series of advertising campaigns in the early 1900s. One of their advertisements even publicized the ability of the .35 Remington to penetrate a 5/16″ steel plate, which the .30-30 Winchester could not do.

The .35 Remington is considered a fine round for deer, elk, black bear, and other medium and large game as long as ranges are reasonable. Hornady currently produces a .35 Remington load in their LEVERevolution line that features a rubber-tipped spitzer bullet which is safe to use in lever action or pump guns with tubular magazines.

Reloading Podcast 239 - lead free bullets

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are discussing lead free bullets for hunting and other stuff.

  1. Mitchell posted in The Reloading Room: Loading some 22-250.

    I have some previously fired brass, which I initially full length resized, loaded, and fired.Now I’m looking at reloading them, and wanting to minimize the amount of working the brass, I was trying to back off the resize die and then working it in gradually to find the minimum resizing required.

What I found is that all of the cases will chamber in the  same rifle with no sizing at all. They are not even a little bit tight. Bolt closes on them the same as if they were resized.

The necks are also not as loose as I’d expect. I can actually put a new bullet in and there is enough tension to hold the bullet so I can seat and apply a slight crimp.

My question is, as long as the rounds chamber well is there any reason for me to size them at all? Also, I’m thinking I don’t even need to neck size, and just want to get other opinions.

  1. Chris McGee posted in RLPG
    Is anyone in here loading for California hunting? If so what bullets are you using? I’m having a hard time finding “lead free”

  2. Joey Commesso posted in RLPG:

    Is a 45 Colt or long Colt as some call it a .451 or .452 diameter bullet. The reloading book has me confused. I just want round or flat nosed Jacketed bullets.

  3. Marc Peck posted in RLPG:

    My dad got me thinking about powder storage the other day. We reload in his shed, it is not climate controlled, but we do have a little window AC unit to cool it in the summer.

    We are in southern Alabama, so the day to day temp swings are not that big, but it does get hot and humid. He got himself some sealed ammo cans to keep his powder out in the shed because they keep the humidity out when we throw in a bunch of desiccant packs. I told him it also need to be a stable temperature, but then got thinking and now have a couple of questions.

    The loaded ammo is kept in the shed after we make it and there seems to be no problem, so why would the powder in a can be a concern?

    Second would it actually be better to keep it out there because it will always be close to the temperature we are loading at?

    I thought of this because if I have my glasses on in the house, then go out and load in the summer, they will fog up if we have not been running the AC unit for a couple of hours first, so if I am taking out a can of powder that is as cold as it was in the house, is it going to draw moisture the same way and be worse than leaving it out there.

    I am posting this on my way out the door for work so I won't be able to answer any questions you guys might have until I get home.

Cartridge Corner Notes:.30-06 JDJ
Overview

The .30-06 JDJ is a modified .30-06 Springfield cartridge designed to be used in the Thompson Center Arms Contender single-shot pistol. The idea behind it is to replicate the ballistics of a .30-06 fired from a rifle in a Contender pistol.


Currently, the .30-06 JDJ is not offered by any manufacturers. Cases and bullets for it can be purchased from various companies for handloaders.


Description

Compared to a default .30-06 round, the .30-06 JDJ contains has a smaller neck that is at a 60-degree angle. However, the biggest difference is that the .30-06 JDJ has little body taper compared to the original .30-06 cartridge. This allows the .30-06 JDJ to hold an extra 5 grains of water (4.875 cm3) compared to the .30-06 Springfield, allowing one to put more gunpowder into the cartridge.


This round manages to replicate in a pistol the ballistics of a .30-06 round fired from a rifle. For example, a .30-06 JDJ cartridge with a 200-grain bullet fired from a custom Contender has a muzzle velocity of 2,504 ft/s (763 m/s), while a regular .30-06 cartridge with a 200-grain bullet with 55 grains of gunpowder has a velocity of 2,558 ft/s (780 m/s).

Reloading Podcast 238 - more questions

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering some questions.

  1. Corey posted in RLP Not a reloading question but before i spend $2,200 on a vortex razor HD gen ii scope. Is there any other scope i should consider around the same price range?

  2. Bryan posted in Matter of Facts Podcast Group: Andrew and Matt, and anyone else with experience or input, I have a few questions regarding my recently acquired 300 blackout.

    First, it doesn’t want to cycle subsonic rounds. It seems like it is not getting enough gas to bring the bolt back far enough to pick up the next round. I have tried to run two different brands of subs through it with the same results. What do you think is causing the issue and what should be my next step to fix it?

    And secondly, the cases that are being ejected have a flat spot at the head of it. I’ll attach a picture for reference. Is this something I should be concerned about, or is it normal behavior?





Cartridge Corner Notes: .257 Weatherby Magnum


From Wikipedia, the free encyclopedia

The .257 Weatherby Magnum is a .257 Caliber (6.35 mm) belted bottlenecked cartridge. It is one of the original standard length magnums developed by shortening the .375 H&H Magnum case to approx. 2.5 in (64 mm). Of the cartridges developed by Roy Weatherby, the .257 Weatherby Magnum was known to have been his favorite, and the cartridge currently ranks third in Weatherby cartridge sales, after the .30-378 Weatherby Magnum and the .300 Weatherby Magnum.[2]


The .257 Weatherby Magnum is among one of the flattest shooting commercial cartridges. It is capable of firing a 115 gr (7.5 g) Nosler Ballistic Tip bullet at 3,400 ft/s (1,036 m/s) generating 2,952 ft⋅lbf (4,002 J) of energy[3] which is comparable to factory loadings of the .30-06 Springfield and the .35 Whelen in terms of energy.


Discrepancies between the metric and U.S. diameters of the bullet may cause some confusion. A .257 bullet has a metric bullet diameter of 6.53 mm. However, in Europe cartridge designation nomenclature for a large part relies on the bore diameter. As the bore diameter of the rifle is .250 inches this would make the .257 Weatherby Magnum a 6.35 mm caliber cartridge rather than a 6.5mm caliber cartridge.

Reloading Podcast 234 - Dings and Squibs

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are covering squib removal, and how bad is a ding before you need to chuck the case.

  1. Hello I have been listening to the podcast and new to r loading. I have been reloading 300 Winchester magnum and 308 Winchester for my bolt guns. I have acquired a 5 gallon bucket each of 223 and 308 typically fired from AR platform rifles. My question is, while sorting out these cases I see many have small dents or dings on the case wall and some scratches on the necks, I assume from the ejecting cycle. Are these cases reloadable? At what point should I discard? Thanks Eric H. Via google voice

  2. Drew posted in RLP Group: What’s the best way to remove a squib?

  3. Hookom posted in RLPG: Another question for the group, I bought some Starline new brass for my new .243 bolt gun. Instead of measuring I'm just gonna run it through the WFT every time I resize. If you were going to trim every time, and it's .243 so there isn't much neck, would you trim at Max, Min or somewhere between. Max is 2.045" and Min is 2.035"

  4. Christopher posted in RLPG: Firearms related. Firing pin on my new .458 socom appears to be lightly piercing the primer every other round or so. Thoughts on sanding down the firing pin with some fine sandpaper. I was shooting a load that was at the bottom of the suggested load ladder. I also need some elevated scope rings oops.

  5. Chris posted in TRRG: Hi, I was pondering on whether or not to purchase Quick Load software. I know NOE bullet molds does a quick load spreadsheet for most of their molds and it seems like it would be a good investment, but I wanted to hear from people who own it.

    Also, I was wondering if it can give a rough estimate of muzzle pressure for different powders and barrel lengths for a specific cartridge. Thanks in advance to all that reply and have a wonderful day.

Cartridge Corner Notes: 7mm Mauser


The 7×57mm cartridge, also known as the 7mm Mauser, 7×57mm Mauser, 7mm Spanish Mauser in the USA and .275 Rigby in the United Kingdom is a first-generation smokeless powder rimless bottlenecked rifle cartridge. It was developed by Paul Mauser of the Mauser company in 1892 and adopted as a military cartridge by Spain in 1893. It was subsequently adopted by several other countries as the standard military cartridge. It is recognised as a milestone in modern cartridge design, and although now obsolete as a military cartridge, it remains in widespread international use as a sporting round. The 7×57mm has been described as "a ballistician's delight".


Many sporting rifles in this calibre were made by British riflemakers, among whom John Rigby was prominent; and, catering for the British preference for calibres to be designated in inches, Rigby called this chambering the .275 bore after the measurement of a 7 mm rifle's bore across the lands.


Optional Read:

7×57mmR (rimmed)


A rimmed cartridge was developed from the 7×57mm shortly after its introduction for use in break-action rifles and combination guns. A rimmed cartridge greatly simplifies the issues of designing an extractor, particularly in a combination gun or "drilling" which must also be designed to extract rimmed shotgun shells.


While various modern break-action and single-shot rifle and pistol designs have been developed that can reliably extract rimless cartridges, most of these date from the 1970s or later.


While the external dimensions of the two versions are nearly identical other than the rim, there are differences in the internal design. In particular, the cartridge web, the area immediately above the rim on the rimmed version or the rebate on the rimless version, is thinner in the rimmed case, and some authorities recommend limiting the rimmed cartridge to 41,000 CUP because of this.

Reloading Podcast 233 - pop goes the pin

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering more questions.

  1. Ernie posted in Reloading Podcast Group: Which universal decapper are you guys using besides the lee?
    .
    Kind of annoyed with my lee universal decapping die. Prior to bending the pin, no matter how tight I tightened it, it would still push up on some crimped primers. Replaced the pin and it’s still doing it. Now I think I’ve just gorilla tightened it and when it slips next I think I’ll have to replace the whole shot.

  2. Jim Rauls posted in RLP: I know it is not officially recommended to shoot powder coated bullets out of a suppressor. That being said , powder coated are my go to for reloading and I’m gearing up to suppress a lever action 44. Anyone here have any advice for me? How bout a show on loading for suppressor applications?

  3. Joe posted in RLP: How often are you supposed to clean reloading dies for both Rifle and Pistol?

  4. Paul posted in RLP: What ballistic software what do you use? Does it link to your weather meter? If so what weather meter do you use? I am using a Weatherflow weather meter, it is bluetooth compatible I use a tablet instead of a smart phone for my ballistic software.


Cartridge Corner Notes:The .444 Marlin (10.9x57mm) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms. It was designed to fill in a gap left by the older .45-70 when that cartridge was not available in any new lever action rifles; at the time it was the largest lever-action cartridge available.[1] The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle.


The history of the cartridge


In the mid-1960s the .45-70 had all but disappeared from the American marketplace. There was no big-bore cartridge available in a lever-action rifle in current production, so Marlin decided to create a new cartridge to fill this empty niche. They created what is essentially an elongated version of the .44 Magnum by making it nearly an inch longer to give it power similar to the .45-70.[3] The case Marlin created is very similar to a rimmed .303 British trimmed and necked-up to work with .429 bullets.[4]


Some hunters initially claimed some trouble because the .444 was frequently hand-loaded using existing .429 bullets that were designed for use at handgun velocities. Remington has stated in letter and email, when asked, that their 240gr .444 bullet was not the same as a .44 magnum handgun bullet.[3] However, diligent end users and DIY ballisticians have conducted detailed tests of projectiles and found that the bullet is identical; indicating that those in contact with Remington, or Remington themselves, spoke in error. The 240grain Remington Soft Point, in both bulk bullet and factory loads, is now reputed to be among to best expanding jacketed bullets for whitetail class game.


Despite the litany of false rumors about the 240 grain bullets, the rifle gained additional popularity as additional bullets were designed for its higher velocity.[5]


In 1972 Marlin re-introduced the .45-70 to their lever-action line, expanding their big-bore offerings.[3] Sales of the .444 are now overshadowed by .45-70 cartridge which has enjoyed a resurgence in popularity due to interest in cowboy action shooting. This quick action and powerful stopping power has been shown to be an efficient and useful hunting rifle for experienced shooters.

Reloading Podcast 232 - You spent how much on a funnel

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering questions about funnels and marking brass.

  1. Shaun C. emailed from the Land Down Under: I’ve been listening to your podcast for a while now and I’m really enjoying it.

    I’m relatively new to reloading, currently reload for 30-06 and 17 Hornet, and waiting to test out some .223 loads (all for hunting)

    Even though I have achieved some great results with my 30-06 & 17 hornet loads, I still have a bit more faith in factory ammo over my handloads when it comes to sighting in a new rifle.

    Can I have your thoughts/opinions, when buying a new rifle do you load up 20 or so rounds of minimum load and use that to sight in then do some load testing? Or do you prefer to sight in using factory?

    Thanks

  2. Ray posted in Reloading Podcast Group: I’m new to reloading and I am having some trouble. When I’m trying to reload my 7 mag and I seat the bullet I can spin the bullet in the case and push it down into it. I have tried different settings and nothing changes.

  3. Ernie K. posted in Reloading Podcast Group: Is there any good way to mark brass so you know how many times it’s been loaded? Was thinking a light punch on the headstamp.

  4. Greg H. posted in Reloading Podcast Group: I am fed up with the plastic fit nothing funnels. What funnels are you using. I have the standard ol rcbs funnel and their one with all the adaptors. Powders like CFE223 go everywhere with these.

Cartridge Corner Notes:45-70 Gov’t The new cartridge was completely identified as the .45-70-405, but was also referred to as the ".45 Government" cartridge in commercial catalogs. The nomenclature of the time was based on three properties of the cartridge:

  • .45: nominal diameter of bullet, measured in decimal inches, i.e., 0.458 inches (11.63 mm);

  • 70: weight of black powder, measured in grains, i.e., 70 grains (4.56 g);

  • 405: weight of lead bullet, measured in grains, i.e., 405 grains (26.2 g).

The minimum acceptable accuracy of the .45-70 from the 1873 Springfield was approximately 4 inches (100 mm) at 100 yards (91 m), however, the heavy, slow-moving bullet had a "rainbow" trajectory, the bullet dropping multiple yards (meters) at ranges greater than a few hundred yards (meters). A skilled shooter, firing at known range, could consistently hit targets that were 6 × 6 feet (1.8 m) at 600 yards (550 m)—the Army standard target. It was a skill valuable mainly in mass or volley fire, since accurate aimed fire on a man-sized target was effective only to about 300 yards (270 m).

After the Sandy Hook tests of 1879, a new variation of the .45-70 cartridge was produced: the .45-70-500, which fired a heavier 500 grain (32.5 g) bullet. The heavier 500-grain (32 g) bullet produced significantly superior ballistics, and could reach ranges of 3,350 yards (3,120 m), which were beyond the maximum range of the .45-70-405. While the effective range of the .45-70 on individual targets was limited to about 1,000 yards (915 m) with either load, the heavier bullet would produce lethal injuries at 3,500 yards (3,200 m). At those ranges, the bullets struck point-first at a roughly 30 degree angle, penetrating three 1-inch (2.5 cm) thick oak boards, and then traveling to a depth of 8 inches (20 cm) into the sand of the Sandy Hook beach. It was hoped the longer range of the .45-70-500 would allow effective volley fire at ranges beyond those normally expected of infantry fire.[5]

Reloading Podcast 231 - Loads of Bacon

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are talking with Loads Of Bacon, You Tuber and creator of The Reloader’s Network.

  1. https://thereloadersnetwork.com/

  2. Loads Of Bacon You Tube channel





Cartridge Corner Notes: 22 Varmiter or 22-250 Remington, a wildcat round that went legit. Originally designed in the 1930’s the 22 Varmiter was to be the 220 Swift but the designer Capt. Wotkyn was shot down by Winchester but used the name 220 swift on Winchesters 6MM Navy Case necked down and shortened to 2.20” and Necked down to .224. Wotkyn, not giving up worked with noted handloader, J. Bushnell Smith and Gunsmith Jerry Gebby. Using the Savage .250-3000 case Wotkyn orginaly wanted to use the three of them perfected the 22 Varminter  going so far as to copyright the name. Phil Sharpe noted gun writer and ballistician became involved when Gebby built him a rifle in the cartridge. Sharpe was working with the 220 Swift at that time and noted that the Varmiter was far more flexible than the 220 Swift. The Swift need to be loaded hot to reach it potential, whereas the Varmiter was flexible in loading from 1500 fps to 4500 fps. Plus case stretching was held to a minimum along with throat wear, due to it’s 28 degree shoulder. Barrel life was greater again due to it steep shoulder angle, the 220 Swift was having problems in those days with shot out barrels. His comments that the Varmiter was a perfect balance of primer, bullet neck length, body taper, load density and shoulder angle.

Accuracy was excellent and Phil pronounced it as the most outstanding cartridge development of the past decade. He was looking for it to become a factory cartridge. He had a long wait it wasn’t until 1963 when Browning Firearms brought out the 22-250.  John Amber in the 1964 Gun Digest said that Browning was asking for trouble with the release of the 22-250! ( John Amber was a friend of mine, during the early days of my shooting hobby)

Finally in 1965 Remington made the stepchild a legitimate cartridge. Today it’s not the fastest 22 centerfire or the most accurate but given the amount of ammo that is sold the 22-250 beats the 220 Swift and the 22 PPC in all factory guns.

Reloaders have lots of choices in bullets and powders, little 35 grain pills to 63 grain round nose for factory barrels. Standard loading of a 55 grain bullet will get you to 3600 FPS to 3800 FPS, take it down a notch to a 45 grain load and you will see 4000 FPS. Powders IMR’s 3031, 4895, 4320, 4064, 4350. ( Once saw a handloader dip his 22-250 case in a cup of IMR 4350 filling right to the top of the case then seat his bullet. Hodgden Ball powders Like H-380 named after Bruce Hodgdon’s load of 38.0 grains behind a 55 grain bullet, H414, BLC-2, and his IMR powders.

Limitations of the 22-250 is barrel twist as 63 grain semi pointed bullets are as heavy as you can go, unless you can get a faster twist barrel. Standard twist is 1-14”, a 1-12” or even a 1-10” twist might be better with bullets we have now.

My Loadings have been for Prairie Dogs so I don’t worry too much about twist rate. I shoot mostly 55 grain flat base bullets and 50 grain boat tails. Some 55 grain boat tails are too long for 1-14” twist.

Loads Please note most if not all are over maximum book

WW case       WLR primer shoulder set back .001 in re-sizing

WW760 40.1 grains, 55 grain Hornady spire point   Velocity is 3800 26” barrel

IMR 4320 34.5 grains, 55 grain Sierra Blitz King Velocity 3650     26” barrel

H380 42 grains 50 grain, Hornady plastic tip                         Velocity 4000 fps  26” barrel

Barrel Life

Prairie dog shooting I may go thru 200 to 500 rounds a day most barrels only last me 2 years at this rate.

I don’t shoot these rifles except for hunting and to check sighting in.

I look at barrels as a cost of the hunt so every couple of years a 600 to 800 cost is not bad.  Thanks to Paul Nelson for the information.

Reloading Podcast 230 - Tirdy Tirdy

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  Tonight the guys are talkin tirty tirdy and some casting.

  1. Chris M. asked: “Mr Fleming, I have a 30-30 question perhaps you could bring up for discussion (if it’s not too much trouble) during a podcast. The question; 30-30 Winchester for a lever action uses a  308 bullet. Could a hand loader use any .308 bullet in that round? For example, I load 168gr ELD’s from Hornady in my .308 loads. Would I be able to use that in a 30-30? Or is it best to just stick with recommended bullet weights for said caliber? I’d love to hear all of your thoughts on this one.”

  2. Brandon posted in CB&BC: So now that hunting season has started or about to start for most, what is everyone’s hunting bullet of choice? My choice this year is the lee 310 gr fn 44 mag at about 10 bhn and moving at about 1,100fps (7.5” barrel) and 1500 fps (20” barrel)Shot from a Ruger Blackhawk hunter and Rossi 92.

  3. Jim posted in CB & BC: I just started researching... Are there any recommendations for resources to cast bullets with something other than lead? I don't mind reading and putting the work in, just wanted to see if there was a recommendation for research. TIA





Cartridge Corner Notes:.30-30 Winchester

The .30-30 Winchester/.30 Winchester Centerfire (7.62×51 mmR) cartridge was first marketed in early 1895 for the Winchester Model 1894 lever-action rifle. The .30-30 (thirty-thirty), as it is most commonly known, was the USA's first small-bore, sporting rifle cartridge designed for smokeless powder.

Characteristics and use

When originally produced by Winchester Repeating Arms (WRA) and Union Metallic Cartridge Company (UMC), it was manufactured with a "metal patched" (jacketed) lead bullet weighing 160 gr. One year later, UMC produced a 170-grain bullet offering, which is still the most popular loading for the cartridge. Both 150- and 170-grain bullets continue to be very popular, as seen in the number of these weights offered by current manufacturers. Although, the 160-grain bullet weight has reappeared in modern cartridges from Hornady, as noted below. Jacketed bullets for the .30-30 are .308 inches in nominal diameter. Cast lead bullets for the .30-30 are also popular and usually are .309 inches in diameter.

The .30-30 is considered to be the "entry-class" for modern big-game hunting cartridges, and it is common to define the characteristics of cartridges with similar ballistics as being in ".30-30 class" when describing their trajectory. While it is very effective on deer-sized and black bear-sized game, most commercial loadings are limited in effective range to about 200 yd (183 m) for that purpose, except when using ballistic-tip ammunition. The cartridge is typically loaded with bullets weighing between 150 and 170 grains (9.7–11.0 g), but lighter loads are possible. Bullets of up to 180 gr (11.7 g) can be used, but the overall length restrictions of the lever-action rifles most commonly chambered for this round limit their usefulness.

In Canada and the U.S., the cartridge has also been used on moose, caribou, and pronghorn. Modern opinions in Canada on its suitability for moose are mixed. Paul Robertson, a Canadian hunting firearms columnist, says, "Too many moose have been taken with the [.30-30] to rule it out as good for this purpose, as well." In both Canada and the U.S. it has a long history of use on moose. It is generally agreed that the .30-30 is not a good choice for hunters who wish to shoot animals at longer ranges. The cartridge, with flat- or round-nosed bullets, does not meet minimum energy standards required for moose hunting in Finland, Norway, or Sweden. Hunting technique and style, as well as law and culture, dictate cartridge choices. Thor Strimbold, a Canadian who has made more than 20 one-shot kills on moose with a .30-30, advises most moose hunters to use more than minimal power if they can handle the recoil. While the .30-30 is legal for hunting moose in Newfoundland, Canada, game authorities do not recommend its use.

One of the primary reasons for the .30-30's popularity amongst deer hunters is its light recoil. Average recoil from a typical 150-grain load at 2,390 feet per second (730 m/s) in a 7.5 lb (3.4 kg) rifle is 10.6 foot-pounds (14.4 J) of felt recoil at the shooter's shoulder, about half that of a comparable rifle chambered for the .30-06 Springfield.

Reloading Podcast 229 - Powder or bullet

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering more questions.

  1. Brandi posted: My boyfriend and I were pondering this last night, so I thought I would ask in The Reloading Room. Let’s say you've chosen a bullet and powder and gone through all the steps in varying charge and seating depth, only to come away with a lot of unimpressive groups. At that point, do you look at changing powder or changing the bullet? I would assume the latter, but I was curious about others' experiences and if putting a different powder under a given bullet could notably improve its performance at similar velocities.

  2. Has anyone loaded a 308 Win load specifically for wolf hunting? What bullet did you choose?

  3. Aaron posted in The Reloading Room: So I'm going to be building a new ar sooner or later the barrel is going to be 18.6” long with 1/8 twist just wondering your thoughts on bullet weight.

  4. Anthony posted in The Reloading Room: For hog hunting in dense timber which do you feel has the most potential and is either significantly more expensive to load for, 45-70 or 20ga sabot? I'm thinking of getting a TC Encore if that helps. Thanks for any help for input.

  5. Alan posted in Reloading Podcast Group: Listening to episode 227 (shotshell) tonight in the truck. Someone asked about the gas cylinder on the Hornady 366 and MEC 9000g presses. It's purpose is to smooth out shell plate rotation, not to control operating speed. I've got a 12ga 366 (1987) and a 2001 20ga 9000g. At high production rates, shot can fly out of the hulls on the 366. Although I haven't run the 9000g fast enough to worry about losing shot out of the hulls, i can see the difference the gas assist makes.

  6. Devin posted in The Reloading Room: My favorite load for my tikka t3 7mm rem mag was 52 grains of imr 4064 under a 150 grain sierra matchking hollow point. I made about 150 rounds! Great groups that touch holes at 100 yards...but my problem is that I just learned that those bullets are not suitable for hunting! I don't know what to do now!

Cartridge Corner Notes:7 MM Remington Magnum

Based on the 300 H & H Magnum Case the 7MM Mag leaves the basic design of the case head but with reduced taper to the case body and a steeper shoulder. SAAMI and CIP specs differ on Chamber pressure with SAAMI MAP being less at 61,000 PSI and CIP at 62,366 psi, CIP Proof load is almost 78,000 psi (77,958 )

This is a flat shooting round capable  of taking all North American game and Most thin skinned African Game.

Little known to most but the 7mm Magnum is a fine target round if you can take the recoil, in fact the United States Secret Service used the 7MM mag as an Anti Sniper Rifle.

Barrel length should be kept at 24” or above with 26” being preferred (28” is even better).

Twist rate of 1 in 9” being standard but with the new longer match bullets you might want to go with a 1 in 7.5”.

Bullet weights range from 100 grains to 197 grains.

As a Hand loader we can tailor our loads to meet almost any game. For Ground Hogs to Eland, Dik-dik to Brown Bear.

Light weight 100 grain pills at 3800 fps to 197 grain match load at 2825 fps for a 24” barrel. I know of long range match shooters that use the 197 grain load that are getting closer to 3000 fps in 30” barrels.

It is critical that the hand loader resize his case properly, that means he should set the shoulder back between .001” to .003” and check bolt closure to make sure that the action cycles smoothly. A good reloading die for this is a Forester Full length sizing die that has been sent to Forester along with 3 fired cases, They then custom fit the die to the rifle chamber. Seating ,mag length and action configuration all play a part. With a good custom action, barrel and stock you can spend around $2600 to $3500 on a custom rifle that will last you and your family generations.

Reloading Podcast 227 - Answering Emails

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering more questions.

  1. Brooks Thornhill posted in Cast Bullets & Bullet Casting: Question - Why do non-cast projectiles require so much additional propellant in comparison to their cast counterparts of the same weight?

  2. David LaMagna posted in The Reloading Room:  Those who have two rifles in the same cartridge, do you have separate FL dies for each rifle?




Cartridge Corner Notes:270 Winchester

The .270 Winchester is a rifle cartridge developed by Winchester Repeating Arms Company in 1923 and unveiled in 1925 as a chambering for their bolt-action Model 54.[3] The cartridge is a necked down .30-03, which is the same length as the .280 Remington, both of which are longer than the .30-06 Springfield. The .270, .280, and .30-06 were all derived from the .30-03 parent case.

The .270 Winchester became a very popular cartridge due to the widespread praises of gunwriters like Townsend Whelen and Jack O'Connor who used the cartridge for 40 years and touted its merits in the pages of Outdoor Life.[4][5] It drives an 8.4 grams (130 gr) bullet at approximately 960 m/s (3,140 ft/s), later reduced to 930 m/s (3,060 ft/s). The cartridge demonstrated high performance at the time of its introduction and was marketed as being suitable for big game shooting in the 270 to 460 metres (300 to 500 yd) range. Two additional bullet weights were soon introduced: a 6.5 grams (100 gr) hollow-point bullet for varmint shooting, and a 9.7 grams (150 gr) bullet for larger deer, elk, and moose in big-game hunting.[3]

While not an immediate success, over the succeeding decades and especially in the post-World War II period, the .270 Winchester attained great popularity among gun owners, metallic silhouette shooters and hunters, ranking it among the most popular and widely used cartridges worldwide. Internationally, firearms manufacturers now offer this chambering in all firearm varieties: bolt-actions, single-shots, lever-actions (such as the Browning BLR), pump-actions (such as the Remington 7600), autoloaders (such as the Remington 7400), and even a few double rifles.[6]

Cartridge corner:


25 - 45 Sharps: The .25-45 Sharps is a firearms cartridge designed by Michael H Blank, then CEO of the Sharps Rifle Company, LLC, as a general hunting cartridge for most North American game, in particular Deer, Antelope, Hogs, and Coyotes. Unlike .300 AAC Blackout which was targeted specifically at the suppressed rifle market, and adapted to hunting, the .25-45 Sharps was designed primarily as a hunting round. That is not to say the round does not have tactical applications as its ballistics exceed that of the 5.56x45mm NATO cartridge. The cartridge name is derived from its caliber (.257) and case length (necked-up 5.56×45), as opposed to older hyphenated cartridges that were named for caliber and powder charge. Factory ballistics with the 87-grain bullet equal those of the original .250-3000 Savage with the same bullet weight.

Reloading Podcast 225 - Dangnabbit You Tube

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are covering lead.

  1. Chris Abbott posted in Cast Bullets & Bullet Casting: Is there a reasonably easy way to turn wheel weight lead into pure lead?

Cartridge Corner Notes:.338 Lapua Magnum:


The .338 Lapua Magnum (8.6×70mm or 8.58×70mm) is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. It was used in the Afghanistan War and the Iraq War. As a result of this, it became more widely available. The loaded cartridge is 14.93 mm (0.588 in) in diameter (rim) and 93.5 mm (3.68 in) long. It can penetrate better-than-standard military body armour at ranges up to 1,000 metres (1,090 yd) and has a maximum effective range of about 1,750 metres (1,910 yd). Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies from 880 to 915 m/s (2,890 to 3,000 ft/s) for commercial loads with 16.2-gram (250 gr) bullets, which corresponds to about 6,525 J (4,813 ft⋅lbf) of muzzle energy.


British military issue overpressure .338 Lapua Magnum cartridges with a 91.4 mm (3.60 in) overall length, loaded with 16.2-gram (250 gr) LockBase B408 very-low-drag bullets fired at 936 m/s (3,071 ft/s) muzzle velocity from a L115A3 Long Range Rifle were used in November 2009 by British sniper Corporal of Horse(CoH) Craig Harrison to establish the then new record for the longest confirmed sniper kill in combat, at a range of 2,475 m (2,707 yd).[4][5]


In addition to its military role, it is increasingly used by hunters and civilian long-range shooting enthusiasts. The .338 Lapua Magnum is capable of taking down any game animal, though its suitability for some dangerous game (Cape buffalo, hippopotamus, white rhinoceros, and elephant) is arguable, unless accompanied by a larger "backup" calibre: "There is a huge difference between calibres that will kill an elephant and those that can be relied upon to stop one."[6] In Namibia the .338 Lapua Magnum is legal for hunting Africa's Big five game if the loads have ≥ 5,400 J (3,983 ft⋅lbf) muzzle energy.[7]

Reviews:

Just listened to Episode 223 (mostly about pressure signs) while driving to an out of town pistol match and pulled over to grab gas and type this. A few things to note.

Firstly on the topic of lube in the chamber, the phenomenon is called bolt-thrust. It’s common to see for 2-3 shots after cleaning your bore if residual cleaning liquid is present, in instances of excessive residual case lube, and even with highly mirror-polished chambers. Effectively the brass cannot “grab” the chamber walls and additional force is transmitted to the bolt face (and thus the bolt lugs) by rearward travel of the case. This manifests itself with higher than normal amounts of primer cratering as well as shiny polished flats on the case head.

Onward to the 1911 stuff, and I’m not trying to be a smartass here, but the pressure signs talked about in the show are largely NOT pressure signs.
1.) The link on a 1911 does not stop rearward movement of the barrel. If it does the gun was improperly built and it will surely break (or slidestop pin will break). This force is absorbed by the frame at the Vertical Impact Surface (VIS) upon being struck by the rear portion of the lower barrel lug (or “feet”) after the link has pulled the barrel down. The link serves one purpose: pull the barrel down after .100” or so of joint travel between barrel and slide.
2.) The upper lugs on a 1911 absorb recoil, but “flanging” and peeking of the forward lug surfaces is also a product of improper barrel fit. As the barrel/slide make their rearward journey together, the link tethers the barrel to the frame and the barrel is forced to rotate down in an arc. If this rotating is impeded by a link that is too long (larger radius arc of travel) or the barrel bed and horizontal impact surface of the frame is cut too high, you get rounding and flanging of the upper lugs as they are not fully clearance of the slide lug recesses when the slide continues back in the recoil cycle.
3.) The back of the barrel hood does not impact the breachface upon firing. It is only when the slide returns to battery that the slide impacts the hood and pushes the barrel forward and up on the slidestop pin via the lower lug radius (and sometimes the link hit we’ll save that argument for another day). Upon firing it’s quite the opposite, the barrel hood and slide are actively being pushed apart by the recoil forces imparted on the breachface (ala bolt face in podcast) and that is impeded by the forward edges of the upper lugs. This isn’t a pressure issue, it’s again a fitting issue. If there is fore-aft slop between #1 lug (front of chamber area) and the breachface, sufficient thrust may be present to cause some peening or cracking but that’s extremely rare. After the first couple hundred or thousand rounds generally all this stretching is done and the slide picks up contact with the #2 lug if it didn’t have any at the start.

The reason I said all that is that the 1911, when built properly, can and has been subject to a steady diet of 55k psi factory loads via the 9x23 Winchester, along with IPSC 38 Super and 9mm Major loads far exceeding 40k. The latter do it with the help of a compensator that delays unlocking by thrusting the muzzle down, thus allowing chamber pressures to drop, and the former does it with a big spring and uber-thick mainwebbed brass. There are guns out there with round counts in the hundreds of thousands shooting such loads.

Cheers,
Kyle

Reloading Podcast 224 - My plunk won't plunk...

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are answering more questions.

  1. Rick posted: Hi all, novice question - I’m attempting to load 9mm rounds for my PCC, but nothing seems to pass plunk test. Using new frontier barrel, upper and lower. I know pistol caliber carbines are picky, but none of my coated and plated bullets will plunk in the barrel at different OAL’s. It will take commercial Aquila 124g RN with an OAL of 1.13 however. So my question is what are some thinner profile 9mm bullets out there for reloading? Anything I might be missing?

  2. Joshua posted: Looking for Advice on .45 ACP. I have read a couple of different opinions about crimping. Some opinions I have read say, “I have to Taper crimp”, and others tell me “Crimp doesn’t really matter so long as it works it works.” I am hoping all of you fine folks can enlighten me. I have been reloading rifle cartridges for awhile now, but I am brand new to pistol calibers. Seems like pistols have the potential to be simple. Should also mention that I am reloading for a 1911.

Reloading Podcast 223 - pop goes the brass

Hello, and welcome to the Reloading Podcast here on the Firearms Radio Network.  

Tonight the guys are discussing over pressure signs.

  1. Over pressure discussion: (Indications of, signs, things to watch out for)
    Discussed at length, all the rest of the questions can be used for next week’s notes.

Cartridge Corner Notes:

The .38-40 Winchester is actually a .40 caliber cartridge shooting .401 caliber bullets. The cartridge was introduced by Winchester in 1874 and is derived from their .44-40 Winchester. This cartridge was introduced for rifles, but in its reintroduction for Cowboy Action Shooting it has seen some popularity as a pistol cartridge. It is not particularly well suited to hunting larger game, but it was popular when it was introduced, along with the previous .44-40 Winchester, for deer hunting. It can be used successfully on smaller game animals, and for self-defense. Current loadings are intended for revolvers.


It is unclear why this cartridge was introduced as it is very similar to the .44-40 from which it was derived. It has approximately 110 ft⋅lbf (150 J) less muzzle energy, and has a muzzle velocity about 110 ft/s (34 m/s) less than the .44-40. The bullet differs by only .026 inches in bullet diameter and 20 grains (1.3 g) in standard bullet weight from the original .44-40. The goal may have been to reduce recoil while maintaining a similar bullet sectional density. One unusual design element of this cartridge is that factory ammunition was loaded with a different case profile than the standard chamber for this cartridge, factory ammunition having a much longer neck than the standard chamber. Most reloading dies are designed to size fired brass to the chamber specification rather than that of the original factory ammunition case profile.


The renewed interest in this caliber can be explained by the increasing popularity of cowboy action shooting  and metallic silhouette shooting. Several single-action revolvers have recently been chambered for this cartridge, including the Ruger Vaquero. Most modern reloading data for this cartridge is found in the handgun section of reloading manuals.


This information was extracted from this Wikipedia Page:

Personally I have had a wee small bit of experience shooting it, but I don’t  own the revolver that I was shooting. I’d say it has a lot more “spit and vinegar” than the mere 357 Magnum Cartridge. (Said tongue in cheek, of course.” But that’s as it should be, it’s a good deal larger than the 357 Case.
