Today is Christmas, and there is plenty of snow on the ground in many parts of the country. 2023 has brought some unusually cold weather to many regions, and we can expect a pretty cold January and February in the higher elevations.
If you plan to go shooting or hunting in the weeks ahead, while the weather is below freezing and snow is on the ground, you need to be prepared. You should always have the right equipment and make sure that you can contact help if something goes wrong (such as not being able to start your vehicle).
The folks at the Precision Rifle Network have created a good video on winter shooting and hunting. Host Marcus Hom provides his TOP 10 TIPS for wintertime shooting/hunting adventures. We recommend that any 4-season shooter watch this video.
TOP 10 TIPS for Winter Shooting and Hunting:
1. Wear Good Sunglasses — With snow on the ground, wearing sunglasses is a must because of the extra reflected light. You can get good sunglasses that also have ANSI Z87.1-approved impact protection.
2. Wear Protective, Moisture-Proof Clothing — Wear a set of Bibs and a long jacket. This will prevent you from getting snow inside your clothing when shooting prone.
3. Take Care of Your Hands — Bring good winter gloves, preferably with a waterproof outer layer. Make sure the inner gloves can work with your trigger/trigger guard.
4. Bring a Good Tripod — A tripod keeps you elevated so you can avoid laying down in snow or slush. That, in turn, avoids body heat loss. “Keeping out of the snow and shooting from an elevated position is pretty important in the wintertime.”
5. Protect Optics and Action — Keep your scope lenses and action clear of moisture, snow, and fog. You will want to have good caps on both lenses. Make sure the action remains closed, and consider some kind of wrap over the action until you’re ready to load and shoot.
6. Ranging Challenges — Laser range-finders don’t perform optimally with intense, bright, ambient light. Also, if it’s showing you may get false readings from snow particles. So take multiple readings to ensure you have the right distance. Also, if you have a reticle with MOA or MIL marks, and you know the size of your target, then you can range the target with the scope.
7. Drop and Windage Info (DOPE) Chart — Bring a waterproof, hard copy dope chart. Out in the field on cold days, a phone battery dies fast, and you’ll want to preserve that battery for emergency phone use if needed. So, you should keep a good old-fashioned drop chart in a waterproof laminate.
8. Muzzle Velocity Issues — Cold temperatures can lower muzzle velocity. Before you go, get an idea of how your velocity will change with low temperatures. Some powders are more sensitive to temperature than others, causing a noticeable reduction in muzzle velocity. A load you’ve worked out in summer may shoot LOW in winter because the actual velocity is low. Even with a “temperature stable” powder you may see a 10 fps slow-down. Do some winter velocity testing if you can before you go.
9. Keep Your Ammo Warm — A simple way to avoid muzzle velocity changes with low ambient temperatures is to keep you ammunition ON YOUR BODY. Have a pouch under your layered clothing where the ammo can be kept relatively warm. See video: 07:50
10. Safeguard Keys and Valuables — Keep keys and valuables in a secure, zippered pocket. “There is nothing worse than losing something… keys, phone, wallet. It’s really hard to find something when its buried under [many] inches of snow”. We also recommend keeping a spare vehicle key hidden on your car/truck. There are magnetic holders that can keep that spare key secure but safely hidden from view.
We think everyone should have a Garand in their gun collection…
Tomorrow is Christmas. In our AccurateShooter Forum, you’ll find a popular thread: “Anybody Get Gun Stuff for Christmas?”. One notable post featured a very special Christmas-week arrival — an M1 Garand barreled action. A Forum member received this CMP-sourced barreled action from a friend and then transformed it with a stunning wood stock and other components. We’d say this is a very successful and handsome holiday project. And get this — the skilled owner, who works as a volunteer armorer, assembled his new M1 Garand in record time: “Well, it took three weeks in-transit for my [Christmas] gift to myself to arrive, but I picked her up at 1400 hours yesterday. Had her built into a complete rifle by 1530….”
If you would like to put together a handsome M1 Garand like the Christmas rifle shown above, you’ll need to start with a barreled action. You can order these, as well as complete M1 Garand rifles, from the Civilian Marksmanship Program (CMP). Below we explain how to order an M1 Garand from the CMP, and how to select the right grade for your needs and budget.
If you have questions about assembling a Garand, contact us and we will put you in touch with the builder of the Christmas M1 Garand rifle. He is a CMP-trained armorer who works to maintain ceremonial rifles for VFW, American Legion, and Disabled Veterans Posts throughout Kentucky.
Ordering an M1 Garand from the CMP — Qualifications
How to Order an M1 Garand from the CMP
To purchase an M1 Garand through the CMP, you must be an adult U.S. Citizen, and a member of an affiliated organization who has participated in a “Marksmanship Activity”. This basically means you need to join a gun club and participate in a clinic or match. Proof of club membership and citizenship is mandatory for all ages. However, the marksmanship requirement is waived for those over 60 years of age. M1 Garands must be ordered by mail or through official CMP Auctions.
It’s not that difficult to order an M1 Garand from the CMP. Along with mail-order sales, the CMP has two stores where M1 Garands can be ordered over the counter and then transferred via your FFL (in compliance with state law). The three CMP stores are located in Anniston, Alabama, Talladega, Alabama, and Port Clinton (Camp Perry), Ohio.
Ordering a Barrel — If you already have an M1 Garand, but the barrel has seen better days, you can order a pre-chambered Criterion barrel in .30-06 Springfield. Criterion tell us: “This is a direct replacement barrel for the M1 Garand rifle, manufactured to mil-spec print #6535448. It has the original G.I. contour and Parkerized finish. Receiver threads are timed, all milling cuts are made, and all M1 Garand barrels are hand-lapped.” NOTE: Each barrel is .010 short-chambered and should be properly headspaced by a qualified gunsmith. These Criterion .30-06 Springfield replacement barrels, priced at $295.00, are legal for use in Service Rifle and John C. Garand matches.
How to Maintain the M1 Garand
Once you have an M1 Garand in your collection, you’ll want to keep it in tip-top condition so it works flawlessly for vintage military matches and fun shooting. Below we’ve linked two good SSUSA articles on M1 Garand maintenance. Following that you’ll find two excellent videos covering M1 Garand Disassembly, Cleaning, and Lubrication. Finally there are links to recommended print manuals for the M1 Garand. If you need spare parts for your M1 Garand, we recommend visiting Garand Gear which carries many key items.
M1 Garand Service and Maintenance
Shooting Sports USA (SSUSA) published an excellent article on Service and Maintenance of M1 Garand Rifles. This offers some smart tricks, such as using smoke from burning masking tape to darken the front sight post.

Recommended M1 Garand Service Manuals
Among the many M1 Garand manuals available, we recommend the CMP’s U.S. Rifle, Caliber .30, M1: ‘Read This First’ Manual. This booklet covers take-down, reassembly, cleaning, lubrication, and operation. The manual comes with CMP rifles or can be purchased for $3.25 from the CMP eStore. The author of Garand Tips & Tricks says: “It’s one of the best firearms manuals I’ve seen and I highly recommend it.” The CMP also offers many other M1 Garand print resources including:
Do you own an M1 Garand, or have you always wanted to acquire one of these legendary semi-auto battle rifles? Well then here is a valuable new resource: The Essential M1 Garand: A Practical and Historical Guide for Shooters and Collectors. This new book by Jim Thompson covers the history of the M1 Garand, and offers practical advice for Garand owners, along with complete parts lists. The book includes annotated military and National Match manuals, a troubleshooting chart, and a section on hand-loading for the Garand. The final Section addresses common questions about the rifle and offers detailed instructions for maintaining this wartime classic. First published in February, 2020, The Essential M1 Garand is available in Print Paperback and Kindle eBook versions. View Table of Contents.
Rimfire .22 LR pistols are great training guns for both novice and seasoned shooters. The minimal recoil and reduced muzzle rise of .22 LR pistols makes them easy to handle, and fast to get back on target. This allows novices to build their basic pistol skills, and helps seasoned competitors upgrade their performance. Even experienced centerfire handgun shooters can improve their skills by cross-training with .22 LR pistols.
Today’s Saturday Showcase features 7 videos covering a large selection of rimfire pistols. Along with these video reviews, serious shoppers should read some articles on the web. Pew Pew Tactical has a good online article that’s definitely worth reading: 9 Best .22 LR Handguns. As the author notes: “Every gun owner should own at least one .22 LR firearm. The ammo is ubiquitous, and affordable at around 5 cents a round.” And BackFire TV has published another good article covering eight popular .22 LR handguns.
Taurus TX 22 Competition — Optics-Ready
The TaurusTX™ 22 Competition model is built on the same full-size polymer receiver as the Taurus TX 22 but has a newly engineered slide and barrel assembly designed to work with red dot optics. The Taurus TX 22 Competition features a “skeletonized” slide with a cutout between the ejection port to just behind the front sight. The mounting system allows the use of the following (but not limited to) sight models: Trijicon RMR, C-More STS 2, Vortex Venom, Doctor Noblex, Burris Fast Fire, Sightmark Mini, Holosun HS507C, Leupold Delta Point Pro.
Eight Popular .22 LR Pistols Reviewed
When initially shopping for a pistol, it’s wise to try a variety of guns from multiple manufacturers. You’ll want to try polymer vs. metal frame, iron sights vs. optics. And try to test-fire the pistols on the type of targets you’ll be using for competition and/or fun shooting. This helpful review video features eight (8) popular .22 LR pistols. In order of appearance these eight rimfire handguns are:
1. Browning Buck Mark Hunter (0:28)
2. Ruger SR22 (1:30)
3. Sig P322 (2:21)
4. Walther WMP (3:30)
5. Taurus TX22 Compact (4:36)
6. Smith & Wesson SW-22 Victory (5:48)
7. KelTec CP33 (6:56)
8. Ruger Mark IV (7:54)
Smith & Wesson Model 41 .22 LR Pistol Review
The S&W Model 41 is a classic American rimfire target pistol. Beautifully crafted, the Model 41 boasts a superb trigger, comfortable grip, and excellent accuracy. New or used, a Model 41 would be a fine addition to any firearms collection.
Browning Buck Mark Pistol Review
Among the most popular .22 LR pistols are the Browning Buck Mark series. Buck Marks are very accurate and very reliable. This rimfire pistol is available in a variety of models starting at under $350.00. Reliable, accurate, and well-crafted, a good Buck Mark will serve you for a lifetime. The tester for the Sootch00 Channel says the “Browning Buck Mark UDX 22 [is] one of the highest quality production .22 LR pistols on the market.” This in-depth, 19-minute Sootch00 Channel review has been viewed over 560,000 times.
SIG P322 Comp Review by 22Plinkster
If you are looking for a well-crafted, .22 LR pistol for action pistol competitions, the SIG Sauer P322 Comp is an option you should definitely consider. The new .22 LR rimfire P322 Comp offers excellent ergonomics and 20+1 capacity, making it good for cross-training and fun rimfire shooting. Note how fast 22Plinkster can hit multiple targets with this new brake-equipped pistol. He observed: “The trigger is really nice and you just want to run it fast”. No question this rimfire pistol would be fun to shoot on steel targets.
Though it may look like a striker-fired pistol, the SIG P322 is a hammer-fired, single-action-only design (the hammer is enclosed by the rear of the slide). The P322 is blow-back operated with a fixed (non-tilting) 4″ barrel. This helps contribute to excellent accuracy and reliability.
S&W Victory Vs. Ruger Mark IV Pistol Shoot-Off
In this video, popular YouTube host 22Plinkster tests two rimfire pistols — the Smith & Wesson Victory and Ruger Mark IV. He favored the grips on the Ruger while preferring the S&W’s trigger. He felt the Ruger’s iron sights were best for precision work, but he noted that the green dot fiber optic sights on the S&W Victory worked better for speed work.
FN 502 .22 LR Tactical Pistol Review
The FN 502 is a modern, hammer-fired design with an optics-ready slide. The barrel is threaded for a suppressor. In this video, popular YouTube gun reviewer Colion Noir tests a FN 502 with suppressor. He was impressed, stating: “This is the best tactical .22 LR handgun I’ve ever shot.”
This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame. For best viewing, you may want to change your video settings to 720p or 1080p High Definition and view full-screen (using the video controls).
The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.
What anti-corrosion products really fight rust effectively? You’ll hear many opinions, but what do actual field tests reveal? One rifle shooter, who posts on YouTube as BlueonGoldZ, wanted to separate myth (and marketing claims) from reality, so he completed his own long-term rust test using metal samples. First he used ordinary tap water spray, and then he did a second, longer-duration test with a salt-spray solution. Nine different products were tested: Break Free CLP, Corrosion-X, Frog Lube, M-Pro 7, Outers, Pro-Shot Zero Friction, Rem Oil, Slip 2000, and Tetra Gun Triple Action CLP.
BlueonGoldZ initially examined each product for its “beading” properties with a normal tap water spray. But the main test involved many multiple weeks of exposure after a “dense” salt-water spray. (No rust formed after two weeks tap water exposure, so the test was accelerated with salt-water exposure).
The clear winners in the test, as shown by the screen shot above, were Corrosion-X (Best), and Frog-Lube (Second Best). The photo shows the test samples two weeks after being sprayed with salt water. The results are pretty dramatic — you can see with your own eyes what happened. We think this is a very useful bit of real-world research.
Results from Similar Long-Term Salt Exposure Test
Unfortunately, BlueonGoldZ’s test did NOT include Eezox, which we have found to be extremely effective (on a par with Corrosion-X). In another long-term test of corrosion preventatives, the two best rust fighters were Eezox and Corrosion-X in that order. Since that test was completed, Corrosion-X, already an excellent product, has been enhanced. CLICK HERE for Long-Term Salt Exposure Test Report.
Forum member Erik Cortina has produced a series of YouTube videos about reloading hardware and precision hand-loading. Here we feature Erik’s video review of the Forster Co-Ax® reloading press. The red-framed Co-Ax is unique in both design and operation. It boasts dual guide rods and a central handle. You don’t screw in dies — you slide the die lock ring into a slot. This allows dies to float during operation.
Erik does a good job of demonstrating the Co-Ax’s unique features. At 1:00 he shows how to slide the dies into the press. It’s slick and easy. At the two-minute mark, Erik shows how sliding jaws clasp the case rim (rather than a conventional shell-holder). The jaws close as the ram is raised, then open as it is lowered. This makes it easy to place and remove your cases.
At the 5:20 mark, Erik shows how spent primers run straight down into a capture cup. This smart system helps keep your press and bench area clean of primer debris and residues.
While many Co-Ax users prime their cases by hand, the Co-Ax can prime cases very reliably. The priming station is on top of the press. Erik demonstrates the priming operation starting at 4:20.
Smart Accessories for the Co-Ax from Inline Fabrications
Forum member Kevin Thomas also owns a Co-Ax press, which he has hot-rodded with accessories from Inline Fabrication. Kevin tells us: “Check out the add-ons available from Inline Fabrication for the Co-Ax. I recently picked up a riser mount and a set of linkages for mine and love the results. The linkages are curved. When you replace the original straight links with these, the work area opens up substantially and the the press becomes much easier to feed.” CLICK HERE for Co-Ax Accessories.

In June 2020, Hornady introduced the 6mm ARC, a new SAAMI cartridge optimized for AR-platform rifles*. The new 6mm ARC is basically a 6.5 Grendel necked down to 6mm, with the shoulder moved back around .030″. That pushed-back shoulder does reduce case capacity (and velocity), but we assume Hornady did that to create a shorter, proprietary chamber so people could not simply neck-down Lapua 6.5 Grendel brass, as has been done for years with Robert Whitley’s outstanding 6mm AR wildcat.
What Is the 6mm ARC Cartridge? The 6mm ARC cartridge is a new SAAMI-spec cartridge based on the 6.5 Grendel case necked down for 6mm bullets, with the shoulder moved back 0.030. Yes it is designed to run in AR15-platform rifles. You’ll need a new barrel, bolt, and mags. If you already have an AR chambered in 6.5 Grendel, the ONLY thing you need to change is the barrel. Everything else — bolt, magazines, gas system – is compatible with 6mm ARC.
▶ Official SAAMI Cartridge (not wildcat)
▶ Fits standard AR15-platform rifles
▶ Fits Short/Mini action bolt rifles
▶ Efficient short, fat case design
▶ 30-degree case shoulder
What Do I Need To Shoot the 6mm ARC?
Faxon and Ballistic Advantage are already producing barrels, with more manufacturers sure to follow. All the other required components are already on the market for 6.5 Grendel rifles. Aero Precision already offers complete 6mm ARC uppers.
If you’re converting a standard 5.56×45 mm (.223 Rem) AR15 upper to shoot 6mm ARC, you’ll need a 6mm barrel, a Type II 6.5 Grendel bolt carrier group, and new magazines. Some folks have suggested standard AR mags will work, but trust us, you want the magazines that have been designed for 6.5 Grendel. Most of the hardware you need is available at Brownells.
* While 6-6.5 Grendel shooters are known to run stout pressures, the new 6mm ARC cartridge has a relatively moderate Maximum Average Pressure (MAP) rating of 52,000 psi according to the official SAAMI specifications. For a variety of reasons, is wise to keep pressures in a semi-auto rifle moderate. Don’t chase the velocities you might get in a bolt-action gun.
Kestrel wind and weather meters are often regarded as the best on the market — for good reason. Here are a series of three videos by F-Class John that show how the Kestrel 5700 with Elite Ballistics works. This article reviews the advanced Kestrel 5700 Elite Wind Meter with sophisticated ballistics capabilities. Our review features three videos by F-Class John that show how the Kestrel 5700 Elite functions with Applied Ballistics APP software and LiNK connection.
This Part I Video starts with a basic Kestrel Anemometer (blue case, 00:00-00:40) wind meter. Then reviewer F-Class John looks at the “smart” Kestrel 5700 with Elite Ballistics. John explains the many features of the Kestrel 5700 and how it holds a powerful ballistics calculator in the convenient, easy-to-tote Kestrel package. With Elite Ballistics, once you enter data about your bullets, velocity, zero, and rifle, the Kestrel can calculate come-ups and wind corrections. If you don’t yet own a Kestrel, we highly recommend you watch this series of videos that explains advanced Kestrel features in detail.
This Part II Video shows the key features of the advanced software APP used by the Kestrel 5700 unit with Elite Ballistics. The Kestrel 5700 can “talk” to a mobile device that runs the Applied Ballistics software APP that contains bullet databases and allows you to enter key information such as muzzle velocity, bullet BC, zero distance, velocity, wind, and environmental factors (altitude, temperature etc.). There are also gun-specific factors such as scope height over bore and barrel twist rate. The video also explains how “range cards” are created and how to view them with your Elite Ballistics-enabled Kestrel. John notes: “The APP is great because you don’t have to fiddle with the Kestrel’s buttons. It’s much easier to enter data and change settings with the APP.”
This Part III video shows how to determine true wind direction by aligning the SIDE of the unit into the wind. You essentially want to set the unit 90 degrees to the wind direction so the impeller runs as slowly as possible. Then, after you set your target distance (See 3:03), the unit can give you precise come-ups for your intended target (10.28 MOA for 559 yards here). The Kestrel then calculates the cross-wind correction as well (See 3:12).

For most larger centerfire cartridges, increased barrel length augments muzzle velocity. That’s why you see F-Open rifles with 30″ and even 32″ barrels. But there is a limit — at some point, increased barrel length may not yield any additional velocity. And in the case of rimfire, too much barrel length can reduce MV. Today’s showcase explores how barrel length affects muzzle velocity, both in centerfire and rimfire rifles.
In the photo above you can see a test rifle fitted with what may currently be the longest barrel fitted to a conventional rifle. This was created by the team at MDT (Modular Driven Technologies) to test how velocity varies with barrel length.
You can see the results of testing with this one-of-a-kind rifle in the MDT video below, the first in our Saturday video showcase. This is followed with an MDT rimfire barrel length/velocity test, and additional tests for the .308 Winchester, 6.5 Creedmoor, and .223 Rem cartridge types.
World’s Longest Rifle Barrel Cut to Determine Velocity Change
This may be the most interesting velocity by barrel length test ever put on video. The MDT (Modular Driven Technologies) team started with a 69″-long barrel, chambered for .308 Winchester. The ammo was Federal Gold Medal match with 175gr Sierra HPBT Bullets (Video 3:30). This barrel had actually been fabricated from multiple sections, a challenge in itself.
Velocity was measured in one-inch increments starting at 69″ and going down to 19″. The speed at 69″ was 2778 FPS while the final speed, at 19″ barrel length, was 2567 FPS. “That is a difference of 211 FPS from the longest point to the shortest point”, observed MDT’s tester. Note that, the velocity did show fairly constant change per inch from 19″ to 45″. So going beyond 36″ inches can actually increase velocity. However, from 45″ to 61″ inches the velocity actually declined a bit. SEE VIDEO at 6:55 time-mark, and check out the chart below.
Ultra-Long .22 LR Rimfire Barrel Cut-Down Velocity Test
This video features Part 2 of MDT’s “Cutting the World’s Longest Rifle” test. This time the team shoots the diminutive .22 LR cartridge from an ultra-long barrel. The results may surprise you: “Get ready to have your assumptions shattered as the MDT team chopped a .22 LR rimfire barrel away inch by inch, recording velocities at each barrel length. In this test, the MDT team looked to determine the optimal length for a .22 LR barrel, from the standpoint of velocity. How long is too long? How short is too short? Does shorter always mean faster? Does longer always mean slower?”
In fact, MDT’s testers determined that, with standard rimfire ammunition, the velocity started to decline after 16″ length. That surprised some of the testers. So with the small .22 LR cartridge, more barrel length can actually reduce muzzle velocity from increased in-barrel friction.
6.5 Creedmoor Barrel Length Test (24″ to 16″)
For this video, testers for Western Powders took a standard test barrel chambered for 6.5 Creedmoor and cut it down one inch at a time. The velocity for five rounds at each length was then measured with a chronograph to determine velocity loss per inch of barrel reduction. Overall the recorded velocity loss from 24″ to 16″ was 197 FPS, almost exactly 25 FPS per inch of length. The velocity loss rate was fairly constant inch by inch, as you can see from the graph displayed at the 4:00-minute mark in the video.
.223 Rem (5.56×45) Velocity Tests (9 Guns, 7.5″ to 20″ Barrels)
In this video, the team from Classic Firearms tests a variety of firearms chambered for .223 Rem (5.56×45). This starts with an Springfield Saint Victor AR-type pistol with a very short 7.5″ barrel. This yielded a 2183 FPS average. Then the team tested eight more guns with increasingly long barrel lengths, adding barrel length with each gun in sequence. The test concluded with a Colt XM16E1 rig with 20″ barrel. That Colt AR averaged 3052 FPS. The guns used (and barrel lengths) are listed below.
The overall results are discussed at the 13:45 Time-Mark.
Test Lengths at Video Time — 7.5″ to 20″
2:11 — 7.5″ Springfield St.V. AR Pistol, 2183 FPS
3:23 — 10.3″ DD MK18 SBR, 2513 FPS
4:34 — 11.8″ PWS MK111 AR Pistol, 2644 FPS
5:35 — 12.5″ IWI Zion AR Pistol, 2789 FPS
.308 Winchester — 16″ Barrel vs. 24″ Barrel Velocity
With the .308 Win cartridge, many hunters prefer a shorter barrel for lighter carry weight. In this video, Gavin Gear of UltimateReloader.com compares .308 Win velocities with a 16″ barrel and a 24″ barrel, shooting the same ammo. Gavin notes: “We asked for input on our .308 build. Overwhelmingly, you all wanted a 16″ barrel, so ‘Shorty’ was born! Looking to compare velocities, I brought out my match .308 Win with a 24″ barrel to compare the results with some Hodgdon data.” CLICK HERE to read full report on UltimateReloader.com.
RifleShooter.com Barrel Cut-Down Testing
Along with these videos, our friends at RifleShooter.com have conducted a number of barrel cut-down tests, starting with fairly long barrels. Velocities were measured with each inch reduction
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.
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.

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.”

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.
YouTube gun video producer 22plinkster has unbridled curiosity when it comes to .22 LR performance. A while back he wanted to see how many Christmas ornaments could be penetrated by one .22 LR round. To answer that burning question, Mr. Plinkster lined up 40 plastic Xmas bulbs in a row and then fired a single round of CCI .22 LR Velocitor ammo through the bunch, using his Henry Golden Boy lever action rifle. Did the bullet penetrate a dozen ornaments? Two dozen? What do you think? Watch the video to find out the surprising answer. The CCI Velocitor ammo is rated at 1435 fps.
