Are you looking to shave POUNDS from your hunting rig or varmint rifle? There are now multiple options for folks looking for a weight-saving, carbon fiber-wrapped barrel. You’ve probably heard about Proof Research. Yes that’s a good company that crafts good products. But now Proof Research has some noteworthy competition — Helix 6 Precision in Washington State.
Helix 6 Precision crafts button-rifled and cut-rifled carbon-wrapped barrels in both conventional and “pre-fit” configurations. Pre-fits are offered for Savage rifles, Ruger Precision Rifle (RPR) series, and SIG Cross rifles. These pre-fit barrels are not cheap. A 6mm Creedmoor RPR pre-fit costs $1099.99, while the Savage pre-fits are also $1099.99 for most chamberings. The conventional (not pre-fit) carbon-wrapped Helix 6 barrel blanks cost $979.99 for most listed chamberings.
While Helix 6 barrels do offer significant weight savings, the founders of Helix 6 say low mass wasn’t the number one design goal: “Accuracy was paramount and weight reduction was secondary. We’ve taken the industry’s most advanced carbon fiber engineering and pushed the technology further with our proprietary … carbon fiber process.”
The founders of Helix 6 Precision say they build some of the best carbon/steel hybrid barrels on the market: “Our unique carbon fiber-layup design dampens barrel harmonics for better accuracy. Each barrel is cut from a 416R stainless steel core, and carbon fiber-wrapped using the Helix 6 Precision’s advanced process. This creates match-grade accuracy barrels with high heat dispersion that are 30% lighter than a steel barrel of the same contour. The bores are … hand-lapped for precision accuracy.” Helix 6 claims its barrels are “lighter, stronger, and faster cooling than anything else available on the market.”
Myth vs. Reality — What Carbon Can and Cannot Do
Carbon fiber is formed using thin strands of carbon bonded together with a plastic polymer resin. The resulting material is very strong and light weight. There’s a reason Formula 1 cars are crafted with carbon-fiber composites. But is a carbon-wrapped barrel the right option for you? Here are some factors to consider:
Weight Savings — There’s no doubt that a carbon-wrapped barrel will weigh less than an unfluted stainless steel barrel with identical length and contour (outside diameters). Helix 6 claims a 30% weight reduction compared to a conventional stainless steel barrel. That’s significant.
Accuracy — Carbon-wrapped barrels are NOT commonly being used for F-Class or Benchrest competition. However, Proof Research carbon-wrapped barrels have performed well in PRS competitions in the hands of top shooters. So, we can conclude that carbon accuracy is good enough for the PRS/NRL tactical game, at least at the local club level.
Heat Dispersion — Carbon-wrapped barrel-makers claim their hybrid design disperses heat better than an all-steel barrel. Some independent testers disagree, saying: “hold on now — the carbon actually acts as an insulator, so more heat is retained in the barrel”. The jury is still out. One thing that is true is that the carbon barrels seem to generate less mirage from barrel heat. Ask yourself, “if less heat is coming OFF the barrel, where is that heat retained?” But the reduced mirage could be a function of the black woven surface which may release heat differently than polished steel.
Pre-Fit, AR, and Custom Barrel Options
Helix 6 precision barrels are available as pre-fits for both Savage and the Ruger Precision Rifle in many popular long-range cartridges. Helix 6 can also thread and chamber a barrel for any precision rifle. And pre-fit AR barrels are available in a wide variety of chamberings and lengths. Helix 6 Precision also supplies carbon-wrapped barrel blanks which can be chambered and fitted by a professional gunsmith. Helix 6 barrel blanks, buttoned-rifled or cut-rifled, are sold in many calibers. Buttoned-rifled barrel calibers are: .224, .243 (6mm), .264 (6.5mm), .284 (7mm), .308 and .338. Cut-rifled barrel calibers are: .224, .243 (6mm), .257, .264 (6.5mm), .284 (7mm), .308, .338, and .375.

The 17 Mach 2 (aka “17 HM2″) is making a come-back. We’re glad. This high-velocity round fits actions and magazines designed for the .22 LR, so it’s an easy barrel-swap upgrade for most rimfire bolt-guns (semi-autos are more complicated). The 17 Mach 2 cartridge doesn’t deliver the velocity of the 17 HMR, but it is still way faster than a .22 LR. Expect 2000-2100 fps with 17 Mach 2 compared to 1250 fps for “High-Velocity” .22 LR ammo. And, importantly, 17 Mach 2 ammo is much less expensive than 17 HMR. If you shop around, you can get 50 rounds of 17 Mach 2 for about $8.60. That’s 43% cheaper than the typical $14.99 price of 17 HMR — a significant savings (17 cents/round vs. 30 cents/round)!
17 Mach 2 Major Selling Points:
1. 60% more velocity than typical “High-Velocity” .22 LR ammo.
2. 40% less cost than average 17 HMR ammo.
3. 17 Mach 2 OAL is compatible with .22 LR receivers and magazines.
17 Mach 2 — Best High Velocity Rimfire Bang for the Buck?
If you are looking for a capable, squirrel-busting round or a fun plinking round, you should definitely consider the 17 Mach 2, especially since CCI has committed to production of the little cartridge. CCI recently rolled out its “Gen 2″ 17 Mach 2 VNT Ammo with polymer tip (see top of article).
Considering that 17 HMR ammo is typically $15 to $17 per box, the 17 Mach 2 is a good value by comparison. It is available from vendors for about $8.60 per 50ct box. That’s $0.17 per round. When you consider overall “bang for the buck”, for many shooters, it makes sense to use the 17 Mach 2 rather than a 17 HMR. You save money, barrel life is a little longer, and the 17 Mach 2 is still a much more potent cartridge than the .22 LR. Check out this comparison, and note how the 17 Mach 2 has a much flatter trajectory than the .22 LR. For varmint shooting, the 17 Mach 2 is clearly the better choice.
Hornady’s 17 Mach 2 has a 2100 FPS muzzle velocity vs. 1255 FPS for “High-Velocity” .22 LR.
17 Mach 2 Rifle Reviews
Gun-makers have taken notice of the availability of 17 Mach 2 ammo, introducing new models chambered for this versatile little rimfire round. For a high-volume, small-species varminting, the 17 Mach 2 is much more effective than the .22 LR, and much less expensive than the larger 17 HMR.
New Savage A17 in 17 Mach 2
There are a number of reviews on new-generation 17 Mach 2 rifles. Recently Varminter.com reviewed the Savage A17 in 17 HM2. Editor Eric Mayer wrote: “This new addition to the A17 line comes at a time when the 17 Mach 2 round is experiencing a resurgence, with ammo now available from CCI and Hornady, including the lead-free NTX round from Hornady. This means … you don’t have to break the bank to buy a current, functioning, semi-auto 17 Mach 2 and you don’t have to … convert your 10/22.”
Eric shot four different types of 17 Mach 2 ammo, putting 1000+ rounds through the Savage. He was impressed: “I am very excited that Savage Arms has chambered their A17 rifle in the 17 Mach 2 / 17 HM2 round. After shooting the prototype, I can confidently say that this new A17 will become my go-to 17 Mach 2 rifle. This new rifle is a great option for varminters everywhere!”
Toggle Bolt Volquartsen Summit in 17 HM2
It’s rare for us to see a new rimfire that we’d really like to own, but the new Summit from Volquartsen fits the bill. This versatile rifle features a cool, straight-pull toggle bolt, similar to those on elite Biathlon rifles. You can see how this gun shoots in this informative 22 Plinkster video:
22 Plinkster Tests Volquartsen Summit Rifle in 17 Mach 2
The 17 Mach 2 (17 HM2) is making a comeback. Now leading manufacturers are offering this efficient little rimfire cartridge in some nice rifles. Both Anschutz and Volquartsen will offer new 17 Mach 2 rifles in 2019. The Volquartsen Summit features a lightweight, carbon fiber-wrapped barrel threaded 1/2-28 for brakes or suppressors. The Summit boasts a nice 1.75-lb trigger pull. The Summit’s CNC-machined receiver features a +20 MOA Rail. NOTE: The video shows a silhouette-style laminated wood stock. However, the Summit comes standard with a composite Magpul stock that actually works better for shooting from a bench.
On Wednesdays, the U.S. Army Marksmanship Unit often publishes a reloading “how-to” article on the USAMU Facebook page. One “Handloading Hump Day” post covered bore-cleaning, specifically the use of pull-through style bore-snakes. Visit the USAMU Facebook page each Wednesday for other helpful tips.
Today, we’ll shift from handloading to rifle bore cleaning and maintenance, with information courtesy of the USAMU’s Custom Firearms Shop. We recently had some inquiries about bore cleaning, and this seems a good opportunity to share. After all, even the best handloads won’t yield their full potential in a poorly-cleaned and maintained rifle.
NOTE: Hoppes claims a trademark on the term “BoreSnake” (one word, no hyphen). For this article, the USAMU has used the term in hyphenated form, two words. We believe the USAMU is referring to a Hoppes Brand Boresnake, not a different bore cleaning rope.
BORE-SNAKES: MIRACLE REPLACEMENT FOR THE CLEANING ROD?
The experiences of both our firearms test specialist and this writer have given no evidence that proper use of a clean bore-snake will damage a match barrel. Of course, one does not pull the bore-snake at an angle to the crown when removing it — pull it straight out, parallel to the bore’s direction, to prevent crown wear over time.
Bore-snakes are very useful for some applications (primarily a hasty, interim wipe-down). In [my] experience they cannot replace a thorough cleaning with a proper rod and brushes. While the experiment cited here involves rimfire, it may help illustrate. Several years ago, the writer used his new, personal Anschutz to investigate the bore-snake issue. It had been fired ~350 rds with match ammo and had had 3 typical rod/brush cleanings.
Next, starting with a clean bore, the writer fired 300 more rounds without cleaning in order to build up a “worst-case” fouling condition. Afterwards, the writer examined the bore with a Hawkeye bore scope. There was a uniform, grey film down the entire barrel, with some small, intermittent lead build-up at and just forward of the throat.
Some bore-cleaning rope products feature separate, detachable bronze brush and bore mop segments. This allows more usage options (e.g. mop only), and makes it easier to clean the brush elements:
A new bore-snake was then wet with solvent and pulled through the bore. The Hawkeye revealed that the grey fouling was gone, and much of the visible fouling at the throat was reduced. However, nine more passes with the bore-snake, checking after each with the Hawkeye, revealed no further improvement in cleaning. The writer then cleaned with two wet patches, observed, then one stroke of a new, wet bronze brush, and one wet patch to clean out residue.
The Hawkeye showed a significant reduction in fouling at the throat; it was virtually gone. A second pass with a wet bronze brush and a wet patch removed the remaining fouling. Scrubbing the bore further, checking to see how much fouling was removed, revealed no significant improvement. The reason for this test was to learn what’s needed to get (and keep) this Anschutz clean with minimal cleaning rod use — and thus, minimal risk of bore damage/wear. Leaving fouling in the bore promotes corrosion over time.
Obviously, this applies to a nice, smooth rimfire match barrel, using good, well lubed ammo. It doesn’t apply directly to the use of copper-jacketed bullets, which leave a stubborn fouling all their own. However, it does suggest that while the bore-snake can be helpful and a useful field-expedient, to truly clean a rifle barrel one will still need a good quality rod, bronze brush and solvents. [Editor: Add a good-fitting cleaning rod bore guide.]
SO, WHAT ABOUT BORE SNAKES FOR BARREL BREAK-IN?
The goal of barrel break-in is to fire each shot through a clean barrel, preventing copper buildup and allowing the bullets their best chance at burnishing sharp edges. Thus, it seems this purpose would be best served by one’s usual rods, brushes and rod guides.
For centerfire rounds, consistent ignition (and low ES/SD) all begins with the primer in the base of the cartridge. When the firing pin strikes the primer, it sets off a small flame/spark which lights the powder in the case. Energy from that burning powder pushes the bullet out of the cartridge, down the barrel, and out to the target. It’s fair to say, then, that accurate shooting all begins with the primer.
When seating primers, consistency counts. You want to make sure the primer is fully seated in the primer pocket in the base of the case. You want to ensure a slight bit of crush (flattening) for proper seating, and it doesn’t hurt to have very consistent primer seating depths. That’s why guys use tools to uniform their primer pockets.
Here’s a tool that lets you measure the consistency of primer seating depths. Forum members have reported it works really well — measurements are quick and repeatable. Will this tool lower your ES/SD or improve accuracy? That’s hard to say. However, it will definitely help you detect when a primer in a loaded round is seated too high or too low — that’s important. In addition, it can give you precise measurements for comparison testing with different types of primers.
Accuracy One Precision Primer Gauge
The Accuracy One Precision Primer Gauge will precisely measure primer pocket depth and the depth of seated primers in relationship to the face of the case head. The Precision Primer Gauge can also be used to measure the thickness of an unseated primer, allowing you to calculate the optimum seating depth for the particular primers and cases you are loading.

Product Tip from EdLongRange. We welcome reader submissions.
On our main Accurateshooter.com website, you’ll find a comprehensive review of the STM system for cleaning cartridge brass with stainless media. To clean brass with stainless media, start with five pounds of small stainless pins sold by StainlessTumblingMedia.com. Place these along with a gallon of water, a little liquid cleaner, and two pounds of cartridge brass in a rotary tumbler, and run the machine for one to four hours.
Forum Member Tests STM System
Our reviewer, Forum member Jason Koplin, purchased the STM media and a new Thumler’s Tumbler. He then tested the STM cleaning procedure on his own brass, including some extremely dirty and tarnished “range pick-up” brass. Jason was thoroughly impressed with how well the STM process worked — as you can see from the “before and after” photos below. Brass which looked like it was ready for the scrap heap was restored to “like-new” appearance. Check it out:
Works Great on Both Rifle Brass and Pistol Brass
The process works equally well on both rifle brass and pistol brass (see below). Jason observed that one surprise benefit of the STM cleaning procedure is a big reduction in noise in his reloading room. Jason said the water-filled rotary tumbler was much quieter than his vibratory tumblers.
You’ll want to read Jason’s full review which shows more before and after images. The full article features a “how-to” video created by Forum member Cory Dickerson, the young man who pioneered the stainless tumbling process and founded STM. The video shows how to load brass, media, and cleaner solutions into the tumbler, and how to separate media from brass once the tumbling is done.
Instead of using the standard .223 Remington or 5.56x45mm NATO round, you have many options for an AR-15. Dozens of cartridge variants have been tried in AR-15s. Some of the most noteworthy and popular alternative chamberings for AR-15s are:
20 Practical — This is simply the .223 Rem necked down to .204 caliber. Requires new barrel. Same bolt, same magazines. Best bang for the buck. .224 Valkyrie — A necked-down version of the 6.8 SPC, the .224 Valkyrie was introduced by Federal a few seasons back. It has better ballistics than the .223 Remington, if used with a suitable barrel. 6mm ARC — Relatively new cartridge that works well for varminting, self-defense, tactical competitions, and deer hunting. Good selection of bullets and factory-loaded ammunition. 6.5 Grendel — Accurate and proven across the course, the 6.5 Grendel requires a new barrel, bolt, and magazines. Most use the 6.5 Grendel for competitive shooting and/or hunting. .300 Blackout — Moderately expensive, the .300 Blackout requires a barrel change. This is used for home defense, and hunting. WARNING — with some bullets this round can be chambered in a .223 Rem barrel, with disastrous consequences. .458 SOCOM — Pretty expensive, requires new barrel and bolt. The .458 SOCOM round is typically used for hunting though it was originally designed for Close Quarters Battle (CQB).
Of these six options, our favorite is the 20 Practical, followed by the 6mm ARC and 6.5 Grendel. The 20 Practical is a great varminting round. Check out our featured 20 Practical AR Rifle Report. This 20 Practical cartridge is highly effective on small varmints, and has shown outstanding accuracy in AR-platform rifles crafted by Robert Whitley.
20 Practical — High-Velocity, Affordable Alternative
The 20 Practical is simply a .223 Remington necked down to .204 caliber. This efficient little cartridge can launch 32-grainers at over 4200 fps, with impressive results on P-Dogs. This makes the 20 Practical a great choice for an AR-based varmint rifle.
20 Practical Ultimate Varminter
A decade ago, as a “proof-of-concept”, AccurateShooter.com created a 20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. That gun was auctioned off, but Robert Whitley continues to produce custom 20 Practical AR15 uppers. (The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard .223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.)
6mm ARC — Popular New SAAMI Cartridge Promoted by Hornady
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 modern 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. All the hardware you need is currently 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.
The 6.5 Grendel — Accurate, Plus Good for Hunters
The 6.5 Grendel round is one of the most accurate cartridges for the AR-15 platform. The 6.5 Grendel round offers a larger-diameter, .264-caliber (6.5mm) bullet running at good velocities. This provides ample energy for smaller game and deer. The 6.5 Grendel is often used for hunting deer up to 300 yards.
History of the 6.5 Grendel Cartridge
The 6.5 Grendel originated as a 6mm PPC necked up to 6.5 mm. After Alexander Arms relinquished the “6.5 Grendel” Trademark, the 6.5 Grendel was standardized as an official SAAMI cartridge. It has become popular with target shooters and hunters alike because it is accurate, efficient, and offers modest recoil. Good for small to medium game, the 6.5 Grendel has been offered in lightweight hunting rifles, such as the Howa 1500 Mini Action.
.224 Valkyrie Cartridge — Impressive with Heavy .22-Cal Bullets
The new .224 Valkyrie was introduced in 2019 as a Hot Rod cartridge that will work in AR15s. Basically a 6.8 SPC necked down to .22 caliber, the Valkyrie has a shorter case than the .223 Remington (and 5.56×45 NATO). This allows you to load the longest, heaviest .224-caliber bullets and still feed reliably from an AR15-type magazine. Designed to rival the .22 Nosler while still running well in ARs, the .224 Valkyrie offers excellent long-range performance when loaded with modern, high-BC bullets. We expect some bolt-action PRS shooters might adopt the .224 Valkyrie. Why? Reduced recoil. With the 90gr SMK, the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil. It can also be a viable alternative to a .22-250 for varminters using an AR platform.
Our friend Gavin Gear of UltimateReloader.com found a superbly accurate load with Berger 80.5gr bullets. Watch this video to learn more:
Sierra Bullets has published extensive load data for the .224 Valkyrie. This covers over a dozen powder types — many more than the Hodgdon database. Sierra’s .224 Valkyrie load data covers projectiles from 50 grain all the way up to 95 grains. With the 90 to 95 grain bullets, the little Valkyrie can give 6mm match cartridges a real run for their money — offering similar ballistics with less recoil. When selecting a barrel for the long .224-cal bullets, specify a fast enough twist rate: “Sierra recommends a 1:6.5″-twist barrel for the #9290 22 cal 90 gr HPBT bullet. However, for cartridges like the Valkyrie, that can push them over 2650 fps muzzle velocity, a 1:7″-twist barrel will stabilize the bullet correctly.”

.224 Valkyrie vs. .22-250 Remington
The Social Regressive explains: “There are two key reasons why the .224 Valkyrie is unique and desirable. First, it is specifically designed to fit the limitations of the AR-15 platform. It does so even when loaded with gigantic bullets, like the 90-grain SMK that Federal announced. The .22-250 Rem is too long and too fat to work in the AR-15 platform; it needs an AR-10 bolt and magazine.”
The .224 Valkyrie has been marketed as a low-recoil round that can stay supersonic to 1300 yards and beyond (with 90gr Sierra MatchKings). Here a Sniper’s Hide duo shots an AR-platform .224 Valkyrie at distances out to 1550+ yards. To be honest, the accuracy wasn’t that impressive. However this test confirms that the .224 Valkyrie does launch the long, heavy projectiles at high enough velocities to prove superior to the standard .223 Rem. Frank Galli (aka “Lowlight”) teams up with Brian Whalen of Colorado Precision Rifle at the Blue Steel Ranch in New Mexico.
The .300 Blackout — Risky Business
The .300 Blackout appeals to folks who want a .30-caliber defense round. This can be loaded at various velocities. Loaded at subsonic speeds and shot with a suppressor, the .300 BLK offers very low sound levels. Unfortunately, that .300 Blackout cartridge can fit in a .223 Rem chamber. Shooting a .308-caliber bullet in .223 bore is a recipe for disaster.
The .300 AAC Blackout aka “300 BLK”, is a compact 30-caliber cartridge designed to work in AR-15 rifles. It has a shorter cartridge case to accommodate the bigger 30-caliber bullet while still fitting in a standard AR-15 magazine. Unfortunately, that’s the danger. A careless shooter can toss a .300 Blackout cartridge in with .223 Rem rounds without noting. And because the case-head size is the same as the .223 Rem (5.56×45) the rifle’s bolt assembly will happily chamber and fire the .300 BLK round. Problem is, that forces a .308 diameter bullet down an undersized .223-caliber bore. Not good!
This images were provided by Tactical Rifle Shooters on Facebook. The message was clear: “Don’t try to run 300 Blackout in your .223/5.56mm. It won’t end well. The problem is identical rifles and identical magazines but different calibers.”
Image from Accurate Shooter Forum. Cutaway shows the jammed .30-Cal bullet:
For those who MUST have a .300 Blackout, here are some things you can do:
1. Use different colored magazines for .300 Blackout vs. .223 Remington.
2. Mark .223 Rem upper handguards with the caliber in bright paint.
2. Fit all your uppers with caliber-labeled ejection port covers.
4. Mark all .300 BLK Rounds with heavy black marker.
Vudoo V22 Ravage with a fluted 18″ Kukri barrel in an Urban Camo Grayboe Ridgeback stock.
Rimfire precision shooting is hot. NRL22 and PRS Rimfire are some of the fastest-growing shooting disciplines in the USA. The NRL now runs 7-8 times as many rimfire matches as centerfire matches these days. The popularity of rimfire precision shooting is easy to understand — .22 LR ammo is a small fraction of the cost of handloaded centerfire ammunition and you can have a fun competition at any local range that goes out to 200 yards or so.
If you’re looking for a top-tier .22 LR precision bolt-action rifle, here is a very impressive option…
Vudoo Gun Works Ravage Precision .22 LR Rifle
Among the most accurate .22 LR precision rifles you can buy is the mag-fed Vudoo Ravage with Ridgeback stock. Popular YouTube gun tester 22Plinkster declared: “It’s a Tack-Driver … this .22 LR Rifle is the most accurate .22 LR bolt-action rimfire rifle I have ever shot in my life.” And he notes that he has shot Anschutz, Lithgow, and other quality rifles.
Firing from a Lead Sled, 22Plinkster starts out at 50 yards, and produced a 0.335″ group at 50 yards using Lapua Midas+ ammunition (4:00 time-mark). Then this session gets really impressive. Continuing with Lapua Midas+ ammo, this Vudoo Ravage produced a sub-half-inch group at 100 yards*. You can watch that Midas+ group form up from 7:20 to 8:25 in the video. Then, with ELEY Tenex ammo, he produced a 0.707″ group (10:30) and an even smaller group (11:55). This complete rifle is available from Vudoo Gun Works for $2905.00 without optics. That a ton of money, but if you compete in the rimfire ELR game, the investment may be worth it, as the exceptional accuracy really makes a difference past 250 yards.
22Plinkster says Vudoo’s Ravage is a top choice for NRL22/PRS rimfire matches and Rimfire ELR competitions: “This is the cream of the crop. [Many] people who are winning PRS rimfire matches are shooting Vudoos. What sets this rifle apart from a lot of the other Match 22 rifles is what it does past 300 yards. A lot of rifles — Anschutz, Lithgow, CZ — shoot really good out to 300 yards. But after 300 yards, their accuracy diminishes big-time.”
If you are interested in getting a Vudoo rimfire rifle, then definitely watch this 20-minute Guns & Tactics video. It provides extensive accuracy testing for multiple ammo types with verified group sizes. Then the reviewer shows the working details of the rifle, including the bolt, trigger system, and magazine. The video also includes field testing from bipod as well as competition-type practical stages out to nearly 400 yards.
This Saturday Movie showcase features four handguns chambered for the modern, high-velocity 5.7x28mm cartridge. In a 5″-6″ barreled pistol, the 5.7x28mm round can achieve very high velocities compared to a 9x19mm (9mm Luger) or .40 SW. The bottle-necked 5.7×28mm cartridge weighs roughly two-thirds as much as a typical 9mm Luger cartridge, allowing more rounds to be carried for the same weight. The cartridge can produce considerable muzzle flash when fired from a pistol, but it has roughly 30% less recoil than the 9mm Luger cartridge, improving controllability. Thanks to its high velocity, the 5.7×28mm has a flatter trajectory than most pistol ammo types.

Ruger-5.7 Pistol Review by Hickok45
In the video above, popular YouTube host Hickok45 reviews the Ruger-5.7, which was introduced in late 2019. This gun has proven reliable and when it hit the market it was much less expensive than its main competitor made by FN. Ruger’s 5.7x28mm pistol is blow-back operated with an internal hammer and ambidextrous thumb safety. The pistol is offered with a 20+1 capacity magazine and an adjustable rear sight paired with a fiber-optic front. Current MSRP is $899.00.

FN Five-SeveN Mk3 MRD Review
In this episode of TFBTV, James Reeves reviews the new FN Five-SeveN Mk3 MRD. At $1,449.00 MSRP, this is the most expensive 5.7x28mm pistol on the market, but might it also be the best? James takes the new Five-seveN Mk3 MRD to the range and to the table to tell you if FN’ lastest, high-tech 5.7x28mm pistol is worth the spend.

Comparison Between 5.7x28mm and 9x19mm
In this video James Reeves compares the performance of the 5.7x28mm round with the 9mm Luger. The 5.7x28mm round certainly offers higher velocity and greater penetration than the legendary 9mm round. Plus common 5.7 magazines hold over 20 rounds. James discusses the advantages of this modern 5.7x28mm cartridge, as well as a few of its shortcomings — such as high cost per round. There is another insightful comparison between the two ammo types on the Ammo-to-Go website. Editor John Lewis notes: “5.7×28 is lighter and faster than 9mm ammo” while the 9mm had a “slight advantage in energy [and was] much better in gel”.
5.7x28mm vs 9mm Penetration Test
In this video the tester shot both 9mm and a 5.7x28mm bullets into horizontal stacks of paper plates. The smaller-diameter 5.7mm bullet penetrated about 40% more paper plates than the 9mm bullet (See video at 3:10-3:35). The 5.7mm bullet basically retained its dimensions in this test, while the hollow-point 9mm spread out slightly. Just mere horizontal penetration can’t tell you the actual effectiveness of the round based in a defensive situation. In a different test using Ballistic Gel, both rounds penetrated adequately but the 9mm created a bigger wound channel. SEE: AmmotoGo.com 5.7x28mm Test.
Short History of 5.7x28mm Guns and Ammo
The FN 5.7×28mm (designated as the 5.7×28 by the C.I.P. and FN 5.7x28mm NATO) is a small-caliber, high-velocity, rebated rim, bottle-necked centerfire cartridge designed for handgun and personal defense weapon uses. It is similar in length to the .22 WMR and somewhat similar to the .22 Hornet or .22 K-Hornet. Unlike many new cartridges, it has no parent case — it was developed from scratch by FN.
The 5.7×28mm was developed in conjunction with the FN P90 PDW and FN Five-Seven pistol in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge (9mm Luger). In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm. The tests compared the relative merits of the 5.7×28mm cartridge and the 4.6×30mm cartridge, which was created by Heckler & Koch.
By 2006, FN’s 5.7×28mm firearms — the P90 PDW and Five-Seven pistol — were in service with military and police forces in over 40 nations worldwide. In the USA, 5.7×28mm firearms are currently used by many law enforcement agencies, including the U.S. Secret Service.
Along with use in military and law enforcement firearms, in recent years the 5.7×28mm cartridge has become popular for handguns in the USA. In December 2019 Ruger unveiled the Ruger-5.7 semi-automatic pistol chambered in this cartridge. In January 2021 Kel-Tec introduced its P50 handgun, which uses horizontal 50-round FN P90 magazines. In January 2021 Palmetto State Armory (PSA) introduced its Rock 5.7 pistol. And this year, Smith & Wesson has released its new M&P 5.7, featured above.
The 5.7×28mm cartridge itself is produced by multiple ammunition makers including Federal, Fiocchi, FN, and Speer. 5.7x28mm ammunition is PRICEY — the cheapest 5.7x28mm ammo we found with a quick search was 40gr Federal American Eagle at $0.77 round. By comparison, you can currently find bulk CCI 9mm Luger ammo for $0.30/round.

GetZone.com has released its annual “What’s Hot at SHOT” video series covering notable new products. There are now nearly 30 new product videos available on YouTube and the GetZone website. You’ll find three of these videos below, featuring the Christensen Arms MHR Rifle, Mossberg Patriot Rifle, and Hornady 7mm PRC cartridge. You’ll find more product videos on GetZone.com and the GetZone YouTube Channel.
Christensen Arms Modern Hunting Rifle
The Christensen Arms Modern Hunting Rifle (MHR) is a versatile, modular design built on an aluminum mini-chassis with V-block bedding. The maker claims that the “MHR provides the accuracy potential of a chassis rifle and the ergonomics of a hunting rifle all while offering exceptional modularity.” The MHR’s stock, forearm, and grips can be swapped out to create a variety of different configurations. You could have one forearm/grip for field carry and another for varmint shooting from a portable bench. This versatility doesn’t come cheap — the MHR starts at a very serious $3499.00 MSRP.
New Mossberg Patriot LR Tactical Rifle
Mossberg showcased a new rifle that should prove popular — the Patriot LR (Long Range) Tactical. This $1085.00 rifle has many excellent features: MDT chassis with V-Block, 20 MOA Picatinny rail, 22″ or 24″ barrel pre-threaded for suppressor, and adjustable cheekpiece and LOP. And like all Patriot rifles, the Patriot LR Tactical has Mossberg’s patented LBA™ (Lightning Bolt Action) user-adjustable trigger with 2 to 7-pound adjustment range. Priced at $1085.00 MSRP, the rifle is currently offered in 6.5mm Creedmoor and .308 Win with 22″ barrel, and 6.5 PRC with 24″ barrel. FULL Specs HERE.
Hornady 7mm PRC Cartridge
The 7mm PRC cartridge is the newest offering in Hornady’s Precision Rifle Cartridge series. The 7mm Precision Rifle Cartridge from Hornady delivers long, heavy caliber bullets in a standard long action. Fitting the niche between the 6.5 PRC and the 300 PRC, the 7mm PRC features temperature-stable, magnum speed propellants for consistent velocity and longer barrel life. Factory rifles are already available or simply swap the barrel on your 7mm Rem Mag or 300 Win Mag and reap the benefits of this long-action, centerfire rifle cartridge.

Bore-snakes are very useful for some applications (primarily a hasty, interim wipe-down). In [my] experience they cannot replace a thorough cleaning with a proper rod and brushes. While the experiment cited here involves rimfire, it may help illustrate. Several years ago, the writer used his new, personal Anschutz to investigate the bore-snake issue. It had been fired ~350 rds with match ammo and had had 3 typical rod/brush cleanings.

The 
This Saturday Movie showcase features four handguns chambered for the modern, high-velocity 5.7x28mm cartridge. In a 5″-6″ barreled pistol, the 5.7x28mm round can achieve very high velocities compared to a 9x19mm (9mm Luger) or .40 SW. The bottle-necked 5.7×28mm cartridge weighs roughly two-thirds as much as a typical 9mm Luger cartridge, allowing more rounds to be carried for the same weight. The cartridge can produce considerable muzzle flash when fired from a pistol, but it has roughly 30% less recoil than the 9mm Luger cartridge, improving controllability. Thanks to its high velocity, the 5.7×28mm has a flatter trajectory than most pistol ammo types.
