U.S. Supreme Court Will Hear New York State Carry Permit Case

New York NRA concealed carry supreme court case
The U.S. Supreme Court will hear NRA-backed case about New York state’s concealed carry laws.

The U.S. Supreme Court has decided to hear an NRA-backed case challenging New York’s restrictive concealed-carry-licensing regime. This sets the stage for the Supreme Court to establish what most states already hold as true, that there is an individual right to self-defense outside of the home. This important case is officially New York State Rifle & Pistol Association, Inc. v. Bruen.

This case challenges the state of New York’s requirement that applicants demonstrate “proper cause” to carry a firearm. New York regularly uses this requirement to deny applicants the right to carry a firearm outside of their home. The NRA believes that law-abiding citizens should not be required to prove they are in peril to receive the government’s permission to exercise this constitutionally protected right.

Speaking about the decision to “grant cert” and hear the case, NRA-ILA Executive Director Jason Ouimet posted: “The [Supreme Court] rarely takes Second Amendment cases. Now it has decided to hear one of the most critical Second Amendment issues. We’re confident that the Court will tell New York and the other states that our Second Amendment right to defend ourselves is fundamental, and doesn’t vanish when we leave our homes.”

According to the NRA-ILA, the number of concealed handgun permits reached 18.66 million in 2019 – a 304% increase since 2007. And many more have been issued in 2020.

In addition to ruling on this statute, this case will give the U.S. Supreme Court the opportunity to clarify the precedent that it has created surrounding the Second Amendment. It has been over a decade since the Supreme Court ruled that the Second Amendment protects an individual right to have a handgun in the home for self-defense in District of Columbia v. Heller. In 2010, the Court also ruled that the Second Amendment is a fundamental right that applies to the states in McDonald v. City of Chicago.

Case is Very Important for Second Amendment Rights
The NRA-ILA states: “It is hard to overstate how important this case is. The decision will affect the laws in many states that currently restrict carrying a firearm outside of the home. NRA-ILA is working hard to defend your constitutional rights and is prepared to argue this case in order to protect the rights of Americans everywhere.”

Don’t Get Caught Short — Make Sure Your Barrels Are Legal Length

short barrel barreled rifle shotgun NSA tax stamp ATF legal brief guncollective.com

The Legal Brief is a feature of TheGuncollective.com that focuses on firearms rules and regulations. In this Legal Brief video, Attorney Adam Kraut explains key State and Federal regulations governing firearms, and explains how to ensure compliance with all applicable laws.

This five-minute video explains barrel length rules for rifles and shotguns, and also explains the best (and most fool-proof) methods to measure your barrel. In addition, the video explains how to measure firearm overall length. A rifle or shotgun which is less than 26 inches overall can also be classified as a “Short-barreled” rifle/shotgun subject to the NFA. NOTE: Under federal law “If the rifle or shotgun has a collapsible stock, the overall length is measured with the stock EXTENDED”.

Highlights of LEGAL BRIEF Discussion of Barrel Length and Firearm Overall Length

The ATF procedure to measure the length of a barrel is to measure from the closed bolt or breech face to the furthest end of the barrel or permanently attached muzzle device. ATF considers a muzzle device that has been permanently attached to be part of the barrel and therefore counts towards the length.

How to Measure Barrel Length: Drop [a] dowel or rod into the barrel until it touches the bolt or breech face, which has to be closed. Mark the outside of the rod at the end of the muzzle crown (if you don’t have a permanently attached muzzle device) or at the end of the muzzle device if it is permanently attached. Remove the rod and measure from the mark to the end of the rod. That is your barrel length[.]

Remember, if the barrel length is less than 16 inches, it is possible that the firearm could be a short barrel rifle (if you are building a rifle or it is already on a rifle) and if the barrel length is less than 18 inches, it is possible the firearm could be a short barrel shotgun (again if you are building a shotgun or it is already a shotgun). Both of these firearms would be subject to the purview of the National Firearms Act and would require the firearm to be registered accordingly.

How to Measure Overall Length:The overall length of your rifle or shotgun may also classify it as a Short Barrel Rifle or Short Barrel Shotgun. The overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore. … If the rifle has a permanently attached muzzle device, that is part of the overall length. … If the rifle or shotgun has a collapsible stock, the overall length is measured with the stock extended.

Bet You Ain’t Seen This Before — Barrel-Indexing Rimfire Action

Bill Myers Indexing Action

The late Bill Myers was recognized as one of greatest rimfire gunsmiths who ever lived. Myers crafted many match-winning, record-setting rimfire benchrest rigs. Here we feature one of Bill’s most interesting creations — a clamping action that allows a rimfire barrel to be indexed (rotated) around the bore axis.

Bill was a creative thinker, and his own exhaustive testing has convinced him that barrel indexing can enhance accuracy in rimfire benchrest guns. Myers did acknowledge that, particularly with a very good barrel, the advantages of indexing may be subtle, and extensive testing may be required. Nonetheless, Myers believed that indexing could improve rimfire accuracy.

Indexing with the Myers’ Clamping Action
To index the barrel, Myers simply loosens the three clamping-bolts and rotates the barrel in the action. Because there is no thread to pull the barrel in or out, the headspace stays the same no matter how much the barrel is rotated. In other words you can rotate the barrel to any position on the clockface and the headspace remains unchanged.

Bill Myers Indexing Action

The Challenge of Barrel Indexing
cone breech bill myers rimfire indexable actionWith a conventional barrel installation, employing a shoulder with a threaded tenon, it is difficult to index the barrel. Even with a cone breech (photo right) that eliminates the problem of extractor cuts, you’d have to use shims to alter the barrel index position, or otherwise re-set the shoulder each time you screwed the barrel in further.

Clamping Action Allows Barrel to Be Rotated to Any Position
Bill has come up with a masterful solution to barrel indexing. He designed and built his own prototype custom action that clamps the barrel rather than holding it with threads. The front section of the action is sliced lengthways, and then clamped down with three bolts. A special bushing (the gold-color piece in photos) fits between the barrel and the action. By using bushings of different inside diameters, Bill can fit any barrel up to an inch or so diameter, so long as it has a straight contour at the breech end. To mount the barrel, Bill simply places the fitted bushing over the barrel end-shank, then slips the “sleeved” barrel into the front end of the action. Tighten three bolts, and the barrel is secure.

AR, Garand, M1A — Six Rules for Semi-Auto Gas Gun Reloading

Reloading for Service Rifles
SFC Lance Dement as featured in CMP’s First Shot Online.

The U.S. Army Marksmanship Unit (USAMU) has published a great series of reloading “how-to” articles on its Facebook Page. This post covers key factors to consider when loading ammunition for Match Rifles and Service Rifles, with a particular focus on self-loading “gas guns”. Visit the USAMU Facebook Page each Wednesday for other, helpful “Handloading Hump-Day” tips.

We offer some “cardinal rules” to help new gas-gun handloaders with safety and efficiency. These address both Match Rifle and Service Rifle versions of the AR15, M1 Garand, M1A, and M110. However, they can also improve safe reloading for many other auto-loaders such as M1 Carbines, FALs, SIGs, etc. The author distilled these principles many years ago to help focus on the essential aspects of these rifles.

RULE ONE: Service Rifles Are Not Benchrest Rifles
Gas-guns require a relatively loose fit between ammunition and chamber (vs. bolt actions) for safe, smooth operation. Many techniques, such as neck sizing and keeping cartridge headspace quite tight, are popular in the extreme bolt gun accuracy realm. However, they are of little value with Service Rifles, and some could even be hazardous. Before adopting a specialized technique, seriously consider whether it is appropriate and beneficial in a gas-gun.

RULE TWO: Never Compromise Safety to Obtain Accuracy
Example: If choosing a brand of great, but ultra-sensitive match primers offers possibly better accuracy at the risk of slam-fires in your design of rifle, don’t do it! You are issued exactly two eyes and ten fingers (best-case scenario). Risking them trying to squeeze 0.25 MOA better accuracy out of an M1A, etc. simply isn’t worth it.

Reloading for Service Rifles

RULE THREE: Tailor the Precision to Your Individual Skill and Your Rifle’s Potential
This has been addressed here before, but bears repeating for newcomers. If you are struggling to break out of the Marksman Class, or using a CMP M1 “As-Issued,” then laboriously turning the necks of your 600-yard brass is a waste of time. Your scores will improve much faster by practicing or dry-firing. On the other hand, if the reigning champions anxiously check your scores each time you fire an event, a little neck-turning might not be so far-fetched.

Verifying Load Improvements — Accuracy hand-loading involves a wide variety of techniques, ranging from basic to rather precise. Carefully select those which offer a good return on investment for your time and labor. In doubt? Do a classic pilot study. Prepare ammo for at least three or four ten-shot groups with your new technique, vs. the same with your standard ammo. Then, pick a calm day and test the ammo as carefully as possible at its full distance (e.g. 200, 300, or 600 yards) to verify a significant improvement. A little testing can save much labor!

RULE FOUR: Be Your Own Efficiency Expert
Serious Service Rifle shooters generally think of ammunition in terms of thousands of rounds, not “boxes”, or even “hundreds”. Analyze, and WRITE DOWN each step in your reloading process. Count the number of times each case is handled. Then, see if any operations can be dropped or changed without reducing safety or accuracy. Eliminating just two operations saves 2000 steps per 1000 rounds loaded. Conversely, carefully consider any measurable benefits before adding a step to your routine.

RULE FIVE: In Searching for Greater Accuracy with Efficiency, Look for System Changes
For example, instead of marking your 300-yard rounds individually to differentiate them from your 200-yard ammo, would a simple change in primers work? If accuracy is maintained, using brass-colored primers for 200 and silver for 300 provides an indelible indicator and eliminates a step! Similarly, rather than spending hours selecting GI surplus brass for weight and neck uniformity, consider splurging on some known, high-quality imported match brass for your 600-yard loads. Results should be excellent, time is saved, and given limited shooting at 600 yards, brass life should be long.

RULE SIX: Check All Your Primers Before Packaging Your Loaded Ammo
This seems simple and even intuitive. However, many slam-fires (which were much more common when M1s and M1As were the standard) are due, at least in part, to “high” primers. Primers should be seated below flush with the case head. The USAMU has addressed this at length in a previous column, but each round should be checked for properly-seated primers before they are packaged for use.

LabRadar Owners — You Should Get this $35 Inertial Trigger

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

SUMMARY: This article reviews a device that “triggers” the LabRadar chronograph to register bullet speed. Rather than activate by sound or Doppler reading, this $35 JKL Inertial Trigger works from the rifle’s instantaneous recoil pulse when a shot is fired. After some frustration with his LabRadar when shooting at a range with reflective surfaces, our tester is now reporting that 100% of his actual shots are being captured correctly by his LabRadar chrono equipped with the JKL Inertial Trigger. He won’t use his LabRadar without it now. Other users have become instant fans of this inertial LabRadar trigger as well. It is very affordable and it works great. VIEW LARGE PHOTO.

JKL Inertial Trigger for LabRadar Chronograph

Product Review by F Class John
The LabRadar chronograph has been one of the most revolutionary tools in the shooting world because of how it collects velocity data, how it reports (and stores) that data, and, ultimately, the ease with which it can be positioned and operated. However, it’s not a perfect system. A majority of the complaints come from users whose LabRadar’s sometimes fail to record all the shots fired in a string. For the average plinker, this may not be an issue. But for serious shooters trying to do ladder tests or load development requiring all shots to be reported, it can be frustrating when a shot is missed.

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

Traditionally, LabRadar has recommended trying different settings that compensate for the gap between the unit and muzzle as well as well as having different options for how the unit recognizes a shot fired. While these options work to some degree, they aren’t a guaranteed fix especially when shooting at ranges with concrete baffles or with roofs, walls, and dividers that can alter sound waves. While nobody can precisely explain why shots are lost under certain circumstances, the fact remains it DOES happen. In addition, the default system can sometimes pick up stray shots from nearby rifles.

Not willing to give up on this sophisticated chronograph, many shooters have looked for a foolproof way to prevent such failures from happening. In fact, for this shooter, the frustration was so high that I actually sold my first LabRadar and went back to another chronograph before ultimately buying another LabRadar almost a year later. But I made that repeat purchase only after vowing to finding a way to make the LabRadar work — EVERY time, for EVERY shot.

See How JKL Inertial Trigger Works in this Video

JKL Inertial Trigger — Outstanding Product That Works Great
Enter the JKL Trigger for the LabRadar. This is an easy-to-use, inertial-driven trigger that activates simply from the recoil of your gun. The unit consists of a small rectangular pad attached to a long audio cable. All you do is plug in the audio cable, attach the pad to your gun with the provided hook and loop (Velcro) material. Then (important), you must change the LabRadar trigger settings from “Doppler” to “Trigger”. The unit works great and is easy to set up. In my experience, the unit will activate no matter where you place it on a stock. However the recoil of every gun is slightly different, so you will need to make sure you find a location that doesn’t interfere with your shooting setup.

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

An unexpected benefit of using the JKL trigger is that it gives you a larger area in which to place your Labradar unit, making it more convenient to setup on benches or range stations. I found this a welcome relief since the LabRadar originally seemed somewhat fussy about where I placed it. Now I can place the LabRadar in more convenient locations — as long as it’s still near my gun and pointed at the target correctly, I get consistent bullet speed data.

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

Are There Issues with “False Positives”?
If there is any downside to using the JKL Inertial Trigger, it’s that a very hard bump or aggressive working of the action can trigger a false reading. However these are easy to identify in your data, because the speed value is way lower than true fired shot values. Simply remove that low entry or otherwise ignore it in your calculations. To be fair, this “bump activation” really doesn’t happen very often once you get used to using the inertial trigger.

SUMMARY — Outstanding Accessory for LabRadar Users
Bottom line — if you own a LabRadar, then definitely get a JKL Inertial Trigger. Priced at just $35.00 this device is not expensive, yet it’s one of the most effective accessories you can buy for the LabRadar. I’ve recommended these inertial triggers to dozens of shooters. Every one of those guys who did buy a JKL trigger says they can’t imagine using a LabRadar without one. If you love what the LabRadar can do, but have been frustrated with shots not getting recorded 100% of the time, then definitely get yourself a JKL Inertial Trigger. It turns a good system into an amazing system. JKL Industries states that its inertial trigger “will work on anything from a .22 LR to a suppressed system or with standard rifle and brake.”

.223 Rem Velocity Per Inch Revealed by Barrel Cut-Down Test

.223 Rem Cut-Down Test barrel UMC m855

Most of us own a .223 Rem rifle. Now, thanks to our friends at Rifleshooter.com we can assess exactly how velocity changes with barrel length for this popular cartridge.

Rifleshooter.com performed an interesting test, cutting the barrel of a .223 Rem rifle from 26″ all the way down to 16.5″. The cuts were made in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .223 Rem/5.56 ammo were chron’d at each barrel length. The Rifleshooter.com team that conducts these tests has a full-service gun shop, 782 Custom Gunworks — visit 782guns.com.

READ RifleShooter.com 5.56/.223 Barrel Cut-Down Test Article »

Test Barrel Lost 25.34 FPS Per Inch (.223 Rem Chambering)
How much velocity do you think was lost, on average, for each 1″ reduction in barrel length? The answer may surprise you. The average speed loss of the four types of .223/5.56 ammo, with a 9.5″ shortening of barrel length, was 240.75 fps total (from start to finish). That works out to an average loss of 25.34 fps per inch.

5.56/.223 Barrel Cut-Down Speed Test 26″ to 16.5″ Start FPS at 26″ End FPS at 16.5″ Total Loss Average Loss Per Inch
UMC .223 55gr 3182* 2968 214 22.5 FPS
Federal M193 55gr 3431 3187 244 25.7 FPS
Win m855 62gr 3280 2992 288 30.3 FPS
Blk Hills .223 68gr 2849 2632 217 22.8 FPS

*There may have been an error. The 25″ velocity was higher at 3221 fps.

See inch-by-inch Barrel Cut-Down Velocity Data HERE »

Rifleshooter.com observed: “Cutting the barrel from 26″ to 16.5″ resulted in a velocity reduction of 214 ft/sec with the UMC 223 55-grain cartridge, 244 ft/sec with the Federal M-193 cartridge, 288 ft/sec with the Winchester M855 cartridge and 217 ft/sec with the Back Hills 223 68-grain match cartridge.”

How the Test Was Done
The testers described their procedure as follows: “Ballistic data was gathered using a Magnetospeed barrel-mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 45.7° F.”

See More Barrel Cut-Down Tests on Rifleshooter.com
Rifleshooter.com has performed barrel cut-down tests for many other calibers/chamberings including 6mm Creedmoor, .308 Winchester, and .338 Lapua Magnum. See these test results at Rifleshooter.com.

.308 Win barrel length cut test

Much Different Results with 6mmBR and a Longer Barrel
The results from Rifleshooter.com’s .223/5.56 test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33″ to 28″ we only lost about 8 FPS per inch. Obviously this is a different cartridge type, but also our 6mmBR barrel end length was longer than Rifleshooter.com’s .223 Rem start length. Velocity loss may be more extreme with shorter barrel lengths. And, of course, different cartridge types and powder/bullet combinations will yield different results.

Sunday Gunday: 20 Practical 4200+ FPS Varmint Slayer

.20 20 practical varmint cartridge .204 Tikka lilja Warren

Do you have .20-Cal fever? Do you yearn to see what a 4200+ fps projectile can do to an unsuspecting prairie dog? Well you could go out and purchase a 204 Ruger rifle, fork over the money for a new, complete die set, and hope that the brass is in stock. Warren B (aka “Fireball”) has a more cost-effective solution. If you have .223 Rem dies and brass, all you need to shoot the 20 Practical is a new barrel and a .230″ bushing to neck down your .223 cases. Warren’s wildcat is simple, easy, and economical. And the 20 Practical matches the performance of the highly-publicized 20 Tactical with less money invested and no need to buy forming dies or fire-form cases. Warren’s cartridge was aptly named. Practical it is.

20 Practical Tikka Bolt Action for Varminting

by Warren B (aka “Fireball”) and Kevin Weaver

After building my 20 PPC, I wanted to do another .20 caliber, this time a repeater for predator hunting that could also serve as a gopher/prairie dog rifle. I wanted to use a Tikka M595 stainless sporter I had. This rifle is the ultimate repeater with an extremely smooth-feeding cycle from its single-column magazine. Since the Tikka was a .223 Remington from the factory, I first looked at possible case designs that would fit the magazine. The 204 Ruger was a very new round at the time and brass was scarce. I also didn’t care for the overly long case design or the standard throat dimensions of the cartridge. I then looked at the 20 Tactical. It was a nice cartridge but I didn’t like the fact that (at the time) an ordinary two-die Tac 20 set with just a plain full-length die and standard seater were $150. Not only did the costs bother me, but I was accustomed to using a Redding die set featuring a body die, a Type-S bushing neck die, and a Competition seater. To be honest, I also didn’t care for the 20 Tactical’s name–there is absolutely nothing tactical about the cartridge. I didn’t want to adopt a new cartridge based on what I perceived to be a marketing gimmick (that “tactical” title).


Warren B, aka “Fireball”, with his Tikka 595. With its smooth action and phenolic single-column mag, it cycles perfectly in rapid fire.

.20 20 practical varmint cartridge .204 Tikka lilja WarrenSimply Neck Down .223 Rem to Make a 20-223 Wildcat
I decided the best thing to do for my purposes was to simply neck down the .223 Rem case and make a 20-223. I already had the dies, the brass, and a rifle that would feed it perfectly. I decided to call the cartridge the 20 Practical because as you will see in this article, it truly is a very practical cartridge. In addition to the generous and inexpensive availability of brass and dies, the 20 Practical is an easy case to create, requiring no fire forming as a final step. Simply neck your .223 Rem cases down, load and shoot.

[Editor’s Note: Over the years, other shooters have experimented with .223 Remington cases necked down to .20 caliber, some with longer necks, some with different shoulder angles. Warren doesn’t claim to be the first fellow to fit a .20-caliber bullet in the .223 case. He gives credit to others who did pioneering work years ago. But he has come up with a modern 20-223 wildcat that involves no special case-forming, and minimal investment in dies and tooling. He commissioned the original PTG 20 Practical reamer design, and he and Kevin did the field testing to demonstrate the performance of this particular version.]

I chose Kevin Weaver at Weaver Rifles to fit and chamber the barrel to my rifle. Kevin does excellent work and is great to work with. Kevin liked the idea of the 20 Practical so much he agreed to purchase the project reamer. (BTW Kevin didn’t even need to purchase a Go/No-Go gauge, he just used an existing .223 Rem gauge.)

Before Kevin ordered the reamer, I talked over the reamer specs with him. My priorities were tolerances on the tight end of the .223 Rem SAAMI specification, a semi-fitted neck with no need for neck-turning, and a short throat so that we could have plenty of the 32gr V-Max in the case and still touch the lands. I also wanted this short throat in case [anyone] wanted to chamber an AR-15 for the 20 Practical. A loaded 20 Practical round will easily touch the lands on an AR-15 while fitting into the magazine with no problem. With its standard 23-degree shoulder, the 20 Practical case also feeds flawlessly through an AR-15.

As for the barrel, I only use Liljas on my rifles. I have had great luck with them. They have always shot well and they clean up the easiest of any barrels that I have tried. I had previously sent my Tikka barreled action to Dan Lilja so that he could program a custom contour into his equipment and turn out a barrel that would perfectly fit the factory M595 sporter stock. There isn’t much material on an M595 sporter stock so the contour had to match perfectly and it did. Dan Lilja now has this custom contour available to anyone who would like to rebarrel their M595 sporter with one of his barrels.

There Are Plenty of Good .204-Caliber Varmint Bullet Options
20 Practical .204 Ruger .20 caliber bullets

How to Form 20 Practical Cases — Simple and Easy
Forming 20 Practical cases is very easy. No fire-forming is required. Start with any quality .223 Rem brass. Then simply run the case into your bushing die with the appropriate bushing and call it done.

Project Componentry
My 20 Practical rifle started out as a Tikka Model 595 Stainless Sporter in .223 Remington. Though the M595 is no longer imported, if you shop around you can find M595 Sporters for bargain prices. Mine cost under $500. I think the action alone is worth that! The receiver has a milled dovetail for scope rings plus a side bolt release like expensive BR actions. The bolt cycles very smoothly. Ammo is handled with super-reliable 3- or 5-round detachable single-column magazines (FYI, Tikka’s M595 22-250 mags will feed a 6BR case flawlessly.) We kept the standard Tikka trigger but fitted it with a light-weight spring. Now the trigger pull is a crisp 1.8 pounds–about as good as it gets in a factory rifle. We replaced the factory tube with a custom, 24″, 3-groove Lilja 12-twist barrel. Dan Lilja created a special M595 sporter contour to allow a perfect “drop-in” fit with the factory stock. For optics, I’ve fitted a Leupold 4.5-14x40mm zoom in low Talley light-weight aluminum mounts. All up, including optics and sling, my 20 Practical weighs just under 8.5 pounds.

Test Report–How’s It Shoot?
I sent the barrel and barreled action to Kevin and in a very short time it was returned. Kevin did a perfect job on the rifle. I had asked him to try to match the bead blasted finish of the Tikka when he finished the new barrel. It came out perfect and the only way one can tell it is a custom is the extra two inches of length and the “20 Practical” cartridge designation.

So, no doubt you’re asking “how does she shoot?” Is my “prototype”, first-ever 20 Practical an accurate rig? In a word, yes. Even with the standard factory stock, and light contour barrel, it can shoot 3/8″ groups. Take a look at the typical target from this rifle. This is from an 8.5-pound sporter with a very skinny fore-end and a factory trigger.

Gunsmith’s Report from Kevin Weaver
The 20 Practical: Origins and Development

Editor’s NOTE: We can’t say for sure who first necked down the .223 Rem to .20 caliber and chambered a rifle for that wildcat (as opposed to the .20 Tactical). But here is an account from way back in 2006 when the Warren B first came up with the idea of a .20 Practical cartridge, complete with reamer specs.

A year ago I received a call from Warren with a great idea. Warren asked “Why couldn’t we simply neck down the .223 Remington case to 20 caliber and get basically the same performance as the 20 Tactical? This way you can forgo the expensive forming dies that are needed for the 20 Tactical.” The idea made perfect sense to me, and I saw no major technical issues, so we got started on the project. I ordered a reamer from Dave Kiff at Pacific Tool & Gauge (PTG) with a .233″ neck. The .233″ neck should allow for a simple necking-down of the 223 Remington case to produce the 20 Practical in just one step. No fire-forming necessary! Furthermore, the PTG 20 Practical reamer Dave created should work with any available .223 Rem brass, commercial or military.

The first 20 Practical round was launched down range (through Warren’s Tikka) just a few months later. The brass formed as easily as expected. All one needs is a Redding type “S” bushing die with a .230 bushing and with just one step I had a .20 caliber case ready to shoot. Warren is brilliant. [Editor’s Note: We concur. For more details on Warren’s case-forming methods and his tips for adapting .223 Rem dies, read the technical sections further down the page.]

It would be almost six months later until I got around to building a dedicated test rifle chambered for the 20 Practical. I used a Remington 722 action, Remington synthetic semi-varmint stock, and a 24″ Douglas stainless steel XX 12-twist barrel. I formed and loaded about 30 cases using Remington brass in about 20 minutes. I used a .223 Rem seating die to seat the 20 Practical bullets. The .223 seating stem seated the small 20-Cal bullets just fine. The first loads sent the 40gr Hornady V-Max bullets down range at a modest 3500 FPS. I did not shoot for groups. I just wanted to use this load to sight in the rifle and break in the barrel. Load development was painless–I used reduced .223 Rem loads for 40gr bullets and worked up from there. In the table below are some of my preferred loads as well as Warren’s favorite recipes for his 20 Practical.

Bullet Wt. Powder Charge Wt. Velocity FPS Comments
32GR H4198 24.1 4025 Warren’s lighter gopher load
32GR AA2460 27.8 4154 Warren’s coyote/prairie dog load
32GR N133 26.0 4183 Coyote/PD load, clean burn
33GR H4198 26.0 4322 Hot Load. Use with Caution!
33GR N133 27.0 4255 Kevin: 0.388” 5 shot group
40GR H335 25.0 3583 Kevin’s barrel break-in load
40GR H4198 24.0 3907 Hodgdon “Extreme” Powder
40GR IMR4895 26.0 3883 Kevin: 0.288″ 5-shot group
40GR N133 25.0 3959 Kevin: 0.227″ 5-shot group
Warren’s Load Notes: My pet loads are all with IMI cases, 32gr Hornady V-Maxs, and Fed 205 primers (not match). These are the most accurate loads in my rifle so far. I haven’t even bothered with the 40s as I have the 20 PPC and 20 BR for those heavier bullets. I prefer the lighter bullets in the 20 Practical because I wanted to keep speed up and recoil down in this sporter-weight predator rifle. Also, the 32gr V-Max is exceptionally accurate and explosive. I like N133 the best as it burns so clean. IMI cases are tough and well-made.
Kevin’s Load Notes: I used Remington 223 cases, Hornady V-Max bullets, and Remington 6 1/2 primers to develop the above loads. CAUTION: all loads, both Warren’s and mine, should be reduced 20% when starting load development in your rifle. All load data should be used with caution. Always start with reduced loads first and make sure they are safe in each of your guns before proceeding to the high test loads listed. Since Weaver Rifles has no control over your choice of components, guns, or actual loadings, neither Weaver Rifles nor the various firearms and components manufacturers assume any responsibility for the use of this data.

Comparing the 20 Practical and 20 Tactical
Kevin tells us: “The 20 Practical and the 20 Tactical are almost identical cartridges. There are only slight differences in case Outside Diameter, shoulder angle, and case body length. The neck length on the 20 Tactical is a bit longer, but there is still plenty of neck on the 20 Practical to grip the popular bullets, such as the 32gr V-Max. Here are some specs:

Cartridge Bolt face to shoulder Shoulder O.D. Shoulder Angle Total length
20 Tactical 1.5232″ .360 30° 1.755″
20 Practical 1.5778″ .3553 23° 1.760″

Both the 20 Tactical and the 20 Practical are fine .20 caliber cartridges. At present, the 20 Tactical is the more popular of the two because it has had more publicity. However, my favorite would be the 20 Practical. Warren’s 20 Practical gives the SAME performance as the 20 Tactical without fire-forming, or having to buy expensive forming dies. So with the 20 Practical you do less work, you shell out a lot less money, yet you give up nothing in performance. What’s not to like? To create 20 Practical cases, just buy a .223 Rem Redding Type “S” Bushing Die set with a .230 or .228 bushing and have fun with this great little cartridge.”

How Bullet Bearing Surface Length Can Affect Load Pressure

USAMU Bullet Ogive Comparison Safety Reloading
Three near-equal-weight 7mm bullets with different shapes and bearing surface.

This article, from the USAMU Facebook Page, concerns reloading safety. In the relentless quest for more speed and flatter ballistics, some hand-loaders load way too hot, running charges that exceed safe pressure levels. Hint: If you need a mallet to open your bolt, chances are your load is too hot. Stay within safe margins — your equipment will last longer, and you won’t risk an injury caused by over-pressure. In this article, the USAMU explains that you need to account for bullet shape, diameter, and bearing surface when working up a load. Don’t assume that a load which is safe for one bullet will be safe for another even if both bullets are exactly the same weight.

USAMU Reloading tips Army Marksmanship

Today, we continue our handloading safety theme, focusing on not inadvertently exceeding the boundaries of known, safe data. Bullet manufacturers’ loading manuals often display three, four, or more similar-weight bullets grouped together with one set of load recipes. The manufacturer has tested these bullets and developed safe data for that group. However, seeing data in this format can tempt loaders — especially new ones — to think that ALL bullets of a given weight and caliber can interchangeably use the same load data. Actually, not so much.

USAMU Bullet Ogive Comparison Safety Reloading

The researchers ensure their data is safe with the bullet yielding the highest pressure. Thus, all others in that group should produce equal or less pressure, and they are safe using this data.

However, bullet designs include many variables such as different bearing surface lengths, hardness, and even slight variations in diameter. In fact, diameters can occasionally range up to 0.001″ by design. Thus, choosing untested bullets of the same weight and caliber, and using them with data not developed for them can yield excess pressures.

This is only one of the countless reasons not to begin at or very near the highest pressure loads during load development. Always begin at the starting load and look for pressure signs as one increases powder charges.

Bullet Bearing Surface and Pressure
Bullet bearing surface length (BSL) is often overlooked when considering maximum safe powder charges and pressures. In Photo 1, note the differences in the bullets’ appearance. All three are 7 mm, and their maximum weight difference is just five grains. Yet, the traditional round nose, flat base design on the left appears to have much more BSL than the sleeker match bullets. All things being equal, based on appearance, the RN/FB bullet seems likely to reach maximum pressure with significantly less powder than the other two designs.

TECH TIP: Bullets of the same weight (and caliber) can generate very different pressure levels due to variances in Bearing Surface Length (BSL).

USAMU Bullet Ogive Comparison Safety ReloadingBullet 1 (L-R), the RN/FB, has a very slight taper and only reaches its full diameter (0.284 inch) very near the cannelure. This taper is often seen on similar bullets; it helps reduce pressures with good accuracy. The calculated BSL of Bullet 1 was ~0.324″. The BSL of Bullet 2, in the center, was ~0.430″, and Bullet 3’s was ~ 0.463″. Obviously, bullets can be visually deceiving as to BSL!

Some might be tempted to use a bullet ogive comparator (or two) to measure bullets’ true BSL for comparison’s sake. Unfortunately, comparators don’t typically measure maximum bullet diameter and this approach can be deluding.

Note: Due to time constraints, the writer used an approximate, direct measurement approach to assess the bullets’ different BSLs. While fairly repeatable, the results were far from ballistics engineer-grade. Still, they are adequate for this example.

Photo 2: The Perils of Measuring Bearing Surface Length with Comparators
USAMU Bullet Ogive Comparision Safety Reloading

In Photo 2, two 7mm comparators have been installed on a dial caliper in an attempt to measure BSL. Using this approach, the BSLs differed sharply from the original [measurements]. The comparator-measured Bullet 1 BSL was 0.694” vs. 0.324” (original), Bullet 2 was 0.601” (comparator) vs. 0.430” (original), and Bullet 3 (shown in Photo 2) was 0.602” (comparator) vs. 0.463” (original). [Editor’s comment — Note the very large difference for Bullet 1, masking the fact that the true full diameter on this bullet starts very far back. You can use comparators on calipers, but be aware that this method may give you deceptive reading — we’ve seen variances just by reversing the comparators on the calipers, because the comparators, typically, are not perfectly round, nor are they machined to precision tolerances.]
