AR-15 Cartridge line-up image from 80% Arms, used with permission. This selection omits our favorite alternative — the 20 Practical (.223 Rem necked down to .204 Caliber).
Instead of using the standard .223 Remington or 5.56x45mm NATO round, you have many options for an AR-15, as shown above. This photo is from Complete Guide to Alternative AR-15 Rounds in the 80% Arms Blog. Some of the most notable alternative chamberings for AR-15s are:
20 Practical — Simply the .223 Rem necked down to .204 caliber. Requires new barrel. Same bolt, same magazines. Best Bang for the Buck. 6mm ARC — The 6mm ARC (from Hornady), is a SAAMI cartridge optimized for AR-platform rifles. The 6mm ARC is basically a 6.5 Grendel necked down to 6mm, with the shoulder moved back around .030″. 6.5 Grendel — Moderately expensive, 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. .50 Beowulf — The most expensive alternative AR-15 cartridge, this requires new barrel and bolt. The .50 Beowulf was created for game hunting, but most hunters use something more practical.
Of these five options, our top choice is the 20 Practical, followed by the 6.5 Grendel. 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
Many years back, 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. 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
The 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 magazines designed for 6.5 Grendel.
While 6-6.5 Grendel shooters are known to run stout pressures, the 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 is becoming a popular chambering in lightweight hunting rifles, such as the Howa 1500 Youth Model.
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.

Hunting season is here. Around the country, game hunters are heading out for their fall deer hunts. For hunters making long treks in the back-country, reducing carry weight is a big deal. That’s why we’ve seen a trend among rifle-makers to introduce rifles that weigh significantly less. This is accomplished through use of carbon fiber stocks, carbon-wrapped or fluted barrels, and even titanium actions. Today’s showcased Weatherby rifles feature these lightweight components. As a result, the Weatherby Backcountry 2.0 Ti (Titanium) model comes in at just 4.7 pounds before optics. That’s mighty light for a hunting rifle.
Weatherby Backcountry 2.0 Ti with titanium action, fluted barrel, and carbon-fiber stock, 4.7 pounds.
Light-Weight, Carbon-Stock Backcountry 2.0 from Weatherby
Here is good news for backcountry hunters. Weatherby’s Backcountry 2.0 carbon-stocked hunting rifles weigh well under 6 pounds before optics. There is even one titanium action model series that weighs just 4.7 pounds. The 2.0 series now offers both standard steel receivers or even lighter titanium receivers. And Backcountry 2.0 Carbon models are equipped with a new carbon fiber stock that is the lightest in the industry — weight is a mere 20 ounces for standard actions. For further weight savings, some models feature a tensioned carbon fiber-wrapped barrel. But all that high-tech doesn’t come cheap — MSRP for the Titanium action, carbon-wrapped barrel model is $3849.00!
Ultralight Carbon Stock — Weatherby’s new Blacktooth stock features a Carbon Link™ bedding system which engages the recoil lug and distributes recoil throughout the stock without the weight of a traditional aluminum bedding block. This makes the overall stock lighter and stiffer.
The Backcountry 2.0 Ti Carbon combines a tensioned carbon fiber barrel with the ultra-lightweight Titanium Weatherby Mark V action. This barrel system has shown excellent accuracy, making it a good choice for a long-range hunter. Registering a very low 5.3 lb starting weight, the Backcountry 2.0 Ti Carbon combines a titanium action with the Peak 44 Blacktooth stock — which Weatherby claims is the “lightest production carbon fiber stock on the market.”
Along with the new ultra-light elements, these Weatherbys have premium Mark V features: 54-degree bolt lift for fast cycling, fluted bolts, TriggerTech triggers, and Cerakote finish on metal parts. All the Backcountry 2.0 series rifles have a sub-MOA accuracy guarantee. CLICK HERE for Weatherby Backcountry 2.0 Field Test by Peterson’s Hunting.
Light is Right — Weatherby’s Backcountry 2.0 rifles weigh as little as 4.7 pounds (before optics).
Weights for Backcountry 2.0 Models range with chamberings:
Weight Saving Secrets — How Weatherby Achieved Such Light Weights GunsAmerica Digest reports: “A huge amount of the weight savings comes thanks to the updated carbon fiber Blacktooth stock by Peak 44. This stock uses what they call their Rock Solid Carbon Link bedding system which eliminates the need for a metallic bedding block. The Blacktooth stock weighs less than 20 ounces. The Backcountry 2.0 [series adds] both a carbon fiber stock and either fluted #1 MOD-profile or #2 MOD-profile carbon steel barrels or #4 MOD-profile BSF carbon fiber-tensioned barrel to achieve these light weights.” READ GunsAmerica Review.
To mitigate recoil Weatherby developed its new 3DHEX recoil pad — the gun industry’s first production 3D-printed pad. The 3DHEX’s three-dimensional honeycombed design extends the duration of the recoil pulse — taking away the sharp kick. Weatherby explains: “With the same amount of recoil spread out over a much greater time period, felt recoil is greatly reduced[.]” Backcountry 2.0 rifle recoil is also reduced by factory-fitted Accubrakes, contoured to match barrel profile.
Field Test of Titanium Action Weatherby Backcountry in 6.5-300 Whby Magnum
In this video, Hunter Todd Helms reviews Weatherby’s Backcountry T1 rifle in 6.5-300 Weatherby Magnum. This rifle is meant for fast and light travel in the backcountry. A fluted barrel, titanium action, and carbon fiber stock minimize weight. Todd says the 3DHEX recoil pad really does tame the magnum kick. This model also features a new streamlined muzzle brake.
Preparations Before The Hunt
1. Map Your Hunt and Notify Others — Before your hunt, make a plan and notify friends and family members about WHERE you are going and your intended return date and time. Print out a Google Satellite map and locate landmarks and trailheads. Mark where you plan to park your vehicle and give a copy of this map to friend and/or family members. A hunter may injure himself by falling off a rock, or tumbling in a creek-bed. After that kind of injury the hunter may be confused or unable to walk. If you get stranded in the wilderness, you want trusted persons to know where you are. So, before you leave on a trip, provide a map to a friend or family member. Show them where you will leave your vehicle, and where you expect to be every day of your hunting adventure.
2. Licenses and Permits — Make sure you have a valid hunting licenses and all the necessary tags. Begin this process with ample time before your intended hunt(s). The NSSF adds: “If you are crossing state or national borders, find out about any special considerations you must take care of. Border crossings can mean knowing about firearm transport laws or Chronic Wasting Disease-related regulations.”
3. Work on Your Fitness — On a multi-day hunt you may be trekking many miles. You need to be in good shape. If you are out of shape you may be putting yourself in a precarious situation, particularly if you underestimate the terrain difficulty. As the NSSF says: “Not being able to handle the conditions lessens your chances of success, can turn a great experience into an agonizing one and can endanger your health.”
4. Do Your Homework — Study the area you will be hunting. Talk to other hunters. Look at satellite photos. Get a real sense of the walking and terrain challenges. For a multi-day hunt, MAKE a PLAN. The NSSF states: “Eliminate surprises. Learn as much about where you will be staying, the area you will be hunting, what the weather might be like and what you need to bring[.]”
5. Rifle and Ammo — Make sure your rifle is sighted-in and your ammo is tested. Sight-in your rifle with the ammo you plan to use on your hunt. CLICK HERE for 4-Shot Sight-in Method. After sighting-in from the bench, confirm your zero by shooting from typical hunting positions (kneeling and with forearm supported on a rock or post).
6. Communications and GPS — Bring a GPS if you are in a wilderness area far from civilization. It’s a good idea to bring a cell phone, but you may not have coverage if you’re quite a distance from populated areas. A smart-phone also doubles as a digital camera to record your trophies. For navigation and safety, consider getting Garmin inReach Explorer+. This high-tech handheld unit features interactive SOS, connecting you to the GEOS 24/7 search-and-rescue monitoring center. They also allow you to send and receive text messages, no matter where you are, via advanced inReach satellite technology. Yes you can communicate even if you are miles from the nearest cell tower.
Visit WhereToHunt.org
There’s a great online resource for hunters that will help you find game locations in your state and ensure you have all the proper permits and game tags. WheretoHunt.org features an interactive map of the country. For all 50 states, the NSSF has compiled information about hunting license and permits, where to hunt, hunter education classes, laws and regulations and more. For each state you’ll also find a link for required applications and license forms.

Bix’N Andy Trigger Showcase — Operation, Specs, Testing
Bix’N Andy makes some of the best triggers you can buy, with versions suited for benchrest, F-Class, ELR, PRS/NRL, as well as hunting and varminting. In this October 2024 video, Gavin looks at the features and functionality of a variety of Bix’N Andy triggers. You can purchase these quality triggers from BulletCentral.com at attractive prices starting at $199.00.
New Caldwell VelociRadar Chirp Radar Chronograph (with App)
In this video Gavin Gear tests Caldwell’s new VelociRadar chronograph. This is quite a bit bigger than the Garmin Xero C1 Pro or the new LabRadar LX compact, yet the VelociRadar is still much smaller than the original orange LabRadar. Notably, the VelociRadar uses a different mode of radar (Chirp Radar vs. Doppler) than other chronos. Caldwell states: “The Caldwell VelociRadar Chronograph [has] cutting-edge Chirp radar technology. While most chronographs stop at only providing muzzle velocity the VelociRadar tracks bullets downrange[.] Using these downrange velocity measurements, the VelociRadar calculates true muzzle velocity, the bullet’s ballistic coefficient, and downrange energy.” Here is one viewer’s comment on the Caldwell unit: “Pros: It is smaller than the original LabRadar, but bigger than the new Garmin. Price point is similar. The Caldwell looks more heavy-duty with reinforced corners, and more likely to survive a fall from the bench top. Control buttons are nice and large. Tripod looks better than Garmin. Cons: The display area looks large, but uses a small portion of that area. The data display should be larger.”
If you are considering purchasing a progressive reloading press — you’ve struck gold. Hosted by Gavin Gear of UltimateReloader.com, this remarkable 79-minute video covers a dozen presses from six leading manufacturers: Dillon, Frankford Arsenal, Hornady, Lee, Mark 7 (Lyman), and RCBS. Set aside plenty of time, because there is a wealth of information — the “mother lode” of progressive press coverage. Along with the big comparison video, Gavin has prepared a detailed, 17-page online article which covers all of the presses in the shootout. This Progressive Press comparison has generated 288,000 views on YouTube. Reviewer Gavin Gear demonstrates how each press works and provides data on costs, output rates, capabilities, and accessories so that potential buyers can make informed purchasing decisions.
6mmGT Rifle Complete Rifle Build, Start to Finish
In this video, Gavin builds an impressive 6mmGT (aka 6GT) field rifle start to finish. You can see him chamber the barrel, fit the bottom metal in the stock, and connect the Bix’N Andy trigger to a 416 Stainless Pristine brand Rem 700-footprint action. This is a multi-purpose rifle, build on the light side with a Carbon Six barrel. Gavin notes: “In this video I chamber a Carbon Six barrel and complete the package with a Bix ‘n Andy trigger, Hawkins Rings, and Riton Scope. Will this be the 6GT Lightweight hunting rifle I’ve been asking for?”
We like the 6GT cartridge, both for PRS/NRL competition and varmint work. The 6GT has the low recoil of a 6 Dasher, with good feeding and mag compatibility. With the 6GT, a competitor can push 105gr bullets at 3000+ FPS or run heavier bullets at 2800-2900+ FPS.
“The [6GT] is a more predictable and barrel-friendly cartridge than the 6mm Creedmoor. It can utilize the accurate and forgiving powders of the 6BR, has fantastic accuracy, and due to its shoulder angle and case length, it doesn’t suffer from feeding issues.” — PewPewTactical.com
LongShot Target Camera
Past 400 yards or so, it can be difficult to see bullet holes on paper, even with spotting scopes. That’s why we recommend a high-quality wireless target camera. The best long-range target cameras on the market are produced by Longshot Camera Systems. The Longshot Target Cam provides a live WiFi camera feed. This comes back to your shooting station and you can view the image with a laptop or mobile device. You don’t need internet coverage and no separate tall antennas are required. Simply place the camera unit next to your target and the receiver unit close to your rifle or bench. The Longshot system is completely self-contained. Longshot produces a variety of cameras starting at $199.00 for the LongShot Marksman. We recommend the $899.00 LR-3 unit which works out to two miles! In this video Gavin Gear of UltimateReloader tests the LR-3 at long range. PRODUCT INFO HERE.
Loading 7mm PRC on a Dillon 550C Progressive — F-Class John
This ULtimate Reloader video features F-Class John, a top-tier F-Class competitor who also has a very popular YouTube video channel. In this video John shows how to load the potent 7mm PRC cartridge with a Dillon 550C progressive press. The 7mm PRC is one of the newer short magnum-style cartridges popular with F-Open competitors. With the 7mm PRC you can drive a 180+ gr 7mm bullet at very impressive velocities with a 28″ or longer barrel.
Anschutz 54.18 .22 LR Rifle for Benchrest and Rimfire F-Class
With the high price of centerfire powders, bullets, and brass, everyone should have an accurate .22 LR rimfire rifle for marksmanship training and competition at 25 to 200 yards. In this video, Ultimate Reloader’s Gavin Gear tests the impressive Anschutz 54.18 BR50-U7 match rifle using a quality Sinclair Int’l front rest. Anschutz offers several versions of the 54.18 and BR-50. There are two barreled actions available: 20″ threaded and 25.9″ non-threaded. Gavin tested the 20″ threaded model with the U7 stock. In this video, Gavin tested the trigger with a sophisticated TriggerScan TS-11. The trigger was superbly repeatable at a measured 3.8 ounces. Gavin also did a bore examination, and tested various ammo. In this rifle, Lapua Midas+ ammo produced the smallest groups. FULL STORY HERE.
Most modern match rifle barrels are stainless steel alloy. These are from Benchmark Barrels.
Though some grades of stainless are more corrosion-resistant, ALL varieties of stainless steel can rust if they are not handled and stored properly.
Some folks feel that they don’t have to worry about rust and corrosion on stainless steel barrels, actions, and other components. That’s not really true. “Stainless” is a bit of a misnomer. First, there are different types of stainless steel alloys, with different degrees of rust resistance. 300 series stainless is more corrosion resistant than the 416 stainless commonly used in barrels. The composition (by percentage weight) of 416 stainless is 0.15% carbon, 12-14% chromium and the rest iron. 416 stainless steel lacks the roughly 10% nickel content that makes the 300 series more corrosion resistant in atmospheric conditions. But because 416 handles pressure better and is easier to machine (than 300 series steel), 416 stainless remains the better choice for barrels.
Though some grades of stainless are more corrosion-resistant, ALL varieties of stainless steel can rust if they are not handled and stored properly. Forum reader Kells81 observed: “Wanna see some rusted stainless? Go to the big “C” brand store in Ft. Worth. Every stainless gun they have on the used gun rack is rusted.” Tom Easly of TRE Custom explains: “Sweat is very corrosive. Sweat and blood will rust many stainless steels. I hate to handle my guns or drip on them when I sweat. It really helps to just wipe them good with a wet rag, dry and wipe on a light coating of gun oil. I think most stainless barrels are made from type 416 stainless, and it is generally pretty corrosion resistant, but not when exposed to sweat, blood, or chlorates (corrosive priming), and some other electrolytes.”
Forum member Jacob, who is studying materials science at LSU, provides this technical information: “The basic resistance of stainless steel occurs because of its ability to form a protective coating on the metal surface. This coating is a ‘passive’ film which resists further ‘oxidation’ or rusting. The formation of this film is instantaneous in an oxidizing atmosphere such as air, water, or other fluids that contain oxygen. Once the layer has formed, we say that the metal has become ‘passivated’ and the oxidation or ‘rusting’ rate will slow down to less than 0.002″ per year (0.05 mm per year).
Unlike aluminum or silver, this passive film is invisible in stainless steel. It’s created when oxygen combines with the chrome in the stainless to form chrome oxide which is more commonly called ‘ceramic’. This protective oxide or ceramic coating is common to most corrosion resistant materials.
Halogen salts, especially chlorides, easily penetrate this passive film and will allow corrosive attack to occur. The halogens are easy to recognize because they end in the letters ‘ine’. Listed in order of their activity they are: fluorine, chlorine, bromine, iodine, astatine.
These are the same chemicals that will penetrate Teflon and cause trouble with Teflon coated or encapsulated O-rings and/ or similar coated materials. Chlorides are one of the most common elements in nature and if that isn’t bad enough, they’re also soluble, active ions. These provide the basis for electrolytes. The presence of electrolytic solutions can accelerate corrosion or chemical attack.”
CONCLUSION: Stainless steel barrels and components won’t rust nearly as fast as blued steel, but you still have to take precautions — particularly removing sweat and corrosive salts from the barrel. Also, don’t let moisture build up inside or outside of the barrel. We recommend wiping your barrels and actions with Eezox, or Corrosion-X after each use. These are both extremely effective rust-fighters that go on thin, without leaving a greasy residue. (Eezox leaves a clear finish, while Corrosion-X has a slightly waxy finish.) Also store your guns in Bore-Store bags when the guns go in the safe. Bore-Stores wick away moisture, and the synthetic fleece inner surface is treated with rust-fighting chemicals. Bore-Stores also protect your guns against dings and scratches.
With the Whidden Click-Adjustable Sizer Dies, you can change shoulder bump by .001″ (one-thousandth) with a simple click. Fast. Easy. Precise.
As handloaders have become more aware of shoulder bump and proper adjustment of the sizer die in recent years, there has become a need for an easier way to adjust the sizer die properly. For most folks, with their conventional dies, it takes lengthy trial trial and error to get the shoulder setback correct. Anyone who has done this can attest that it can be a slow and annoying job.
Whidden Gunworks has solved the problem with the innovative Click Adjustable Sizer Die. Patent No: 10,393,488. This die and lock ring work together to give the user a clicking feel to the adjustment just like a high end rifle scope. Each click moves the shoulder bump exactly .001″ so you can easily find the exact shoulder bump that you desire.
The Click Adjustable option is available on Whidden Custom Sizer dies as well (7/8”-14 format dies only)! Included with the Click Adjustable Sizer Die is a Shoulder Bump Gauge. This gauge attaches to standard calipers and allows measurement from the case shoulder to the base. Using the Shoulder Bump Gauge with the Click Adjustable Sizer Die will make the proper sizer die setup easier than ever before.
Click-adjustable die sets are available with both bushing and non-bushing configurations. Along with these complete die sets, Whidden Gunworks offers a separate click-adjustable ring to use with existing dies. Priced at $58.99, the Whidden Click-Adjust Lock Ring represents a modest investment for a major gain in die ease-of-use and precision adjustability.
The Whidden Universal Click Adjustable Lock Ring you can instantly turn your sizer die into a Click Adjustable Die. This ring works with any 7/8 OD sizer of any brand with adjustable shoulder bump. Simple in design, the inner and outer ring can rotate independently of each other. Each click is metered in true 1 thousandths adjustment and has 0.100″ total available travel. These work great with nearly all sizing 7/8 OD sizing dies, and one verified purchaser noted: “Not only are they useful on reloading dies, but it’s the cat’s meow on the Giraud Power Trimmer Case Holders.”
Dillon Users Take Note: The Whidden Click Adjustable Sizing Die will not work with the Dillon 550 or 650 progressive reloading press systems. The Universal Click Adjustable Lock Ring is not compatible with the Dillon floating toolhead.
The late Bill Myers was recognized as one of greatest rimfire smiths 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.
The Challenge of Barrel Indexing With 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.
This stunning Westley Richards & Co. shotgun was made for the 1981 nuptials of Lady Diana Spencer and HRH Prince Charles. It is rare, has a unique history of ownership, and is also elaborately decorated.
Jim Supica, Director of the NRA Firearms Museum, has written a trio of articles about gun collecting. If you are thinking of starting your own collection of firearms, you should read Supica’s informative articles. The first talks about the basics of gun collecting, the second explains the five key factors that govern gun values, and the third article explains where to find rare and valuable arms. Today we want to highlight the five factors that contribute most to a gun’s value, according to Supica:
Make and Model, Condition, Rarity, History, Art — These are the five factors that … appeal to collectors and help determine the value of collectible guns.
Make and model tends to be the starting point for evaluating collectible guns for most collectors and will be a basic threshold requirement for those with specialized collections.
Factors here include the quality of a particular manufacturer’s products, the historical usage of the guns in question, and the brand’s aura of romance. As an example of that last (and most intangible) factor, consider that Colt Single Action Army revolvers were for several decades the most prevalent focus for collectors interested in full-size revolvers from the post-Civil War to turn of the 20th Century-era, and there is no question that Colts were widely used during that time. In recent years, there has been a refreshing trend in gun collecting to look at a broader range of guns than the traditional blue chip Colts, Winchesters, and Lugers.
Colt Single Action Army Revolvers remain among the most prized (and collectible) firearm.
2. Condition (and Originality)
Obviously, condition plays a major role in the value of a collectible firearm. The classic advice to new collectors in this regard has always been to hold out for guns in the best condition and pay the extra premium they demand. This condition-emphasis seems to have developed in the 1970s and 1980s. In the early post-WWII years of gun collecting there was more interest in rare variations and history, and fewer collectors to whom a few percentage point difference in remaining original finish was of much concern.
Although the highest-condition guns continue to bring record prices, it seems that the pendulum is beginning to swing back the other way, a trend met with my hearty approval. The appeal of “mint” guns has been largely lost on me, and seems to be more appropriate to coin or stamp collecting than a field in which the possible historic usage of the artifact holds so much interest and significance. There is a definite segment of the collector market that is not overly concerned with perfect condition, so long as the gun is original and has not been messed with in a more recent (and, in my opinion, usually misguided) attempt to enhance its desirability.
3. Rarity
In terms of rarity, the well-worn saying that “just because a gun is rare doesn’t mean it’s valuable” remains true to a certain extent. There may only be five known examples of a particular gun, but if only three people care about it, the market is saturated. However, there does seem to be more interest in cornering the rare variations within established collecting fields. There is a bit of a resurgence of the collecting philosophy of completing a punchlist of models and variations within a specialization, and this lead to vigorous competition for the rarest examples in these fields. In emerging collecting fields, when new research is published revealing the rarity of certain variations there can develop a brisk interest in those guns.
4. History
Individual guns with a known history of ownership by a specific individual or usage in a specific historical event have always captured the fascination of collectors, as well as historians and the general public. This seems to reflect a basic human interest and shows no sign of abatement. A positive trend here seems to be an increase in general understanding of the type of documentation which must accompany a historically attributed firearm to give it the credibility to justify a premium price, and the importance of creating and preserving such documentation.

5. Art (Decorative Embellishment)
Fine engraved guns are collected more for their artistic value than for their worth as firearms. Here the market for classic works by the great engravers of the 19th and early 20th Centuries remains strong, as well as for factory-engraved pieces from more recent years. Interest in recent non-factory engraving seems to have diminished, as has… the trend of adding modern engraving to older firearms.
Here is a matching set of three three beautifully engraved pistols by the late Indiana engraving wizard Ben Shostle — a Luger, a Mauser, and a Colt. Photo courtesy Amoskeag Auction Company.
Factory-custom engraving should not be confused with mass-produced, factory-made commemorative firearms, which flooded the market in the 1960s and 1970s. A couple of major manufacturers worked this genre to death, and prices on commemoratives have been stagnant for many years now, although the market for these shows some signs of renewal.
CAUTIONARY WORDS about RESTORATION
With prices for high-condition original finish guns running away from the budgets of many collectors, period-of-use refinished guns and older factory-refinished guns are finding more enthusiastic buyers than they did a few years ago.
The availability of excellent-quality restoration services is another factor that I anticipate may impact collector preferences in the future. The top restoration artists are reworking guns to “as new” condition with such skill that it has become increasingly difficult for even knowledgeable collectors to distinguish mint original finish guns from the best restorations.
When such restoration is disclosed to a prospective buyer (as it ethically should be), the prices the gun will bring are significantly below a similar gun with original finish, and may be less than the original cost of the pre-restoration gun plus the cost of the rework. This creates a mighty incentive for deception by a motivated seller, either by active misrepresentation (a.k.a. “fraud”) or passively by simple failure to mention the modification.
Hunting season is underway around the country. If you need a good hunting rifle, consider a Tikka. The Tikka T3 and newer T3x rifles are very popular with hunters around the globe — for good reason. These rifles offer smooth-running actions, easy sub-MOA accuracy with good ammo, crisp triggers, and ultra-reliable detachable box magazines. The Tupperware stocks aren’t super-rigid, but they are comfortable and easy to handle. If you are looking for a hunting rifle, the Tikka T3 and T3X models are smart choices, offering good performance for the price (starting at $749.00 for the T3X Lite version). The T3 series is offered in a wide selection of chamberings, from .204 Ruger up to the large magnums.
Here are three good Tikka T3/T3x video reviews. The first, from the popular Backfire YouTube channel covers the features of the Tikka T3 series. The second video, from an experienced hunter in New Zealand, explains cover the T3’s controls and how to use the rifle most effectively during a hunt. Last but not least is a Hickok45 video examining the T3x’s controls and ergonomics. This video also demonstrates the T3x’s accuracy on steel targets.
VIDEO One — Why the Tikka T3x Is Great for Hunting
With 800,000+ subscribers, the Backfire Channel is one of the most popular gun channels on YouTube. You can trust what the Backfire reviewers say because they pay their own money for the products they review. This video reviews Tikka’s current generation T3s rifle. Backfire had high praise for Tikka T3x rifles: “The Tikka T3x SL is an incredibly lightweight mountain rifle that should be in every hunter’s safe. We like it for its lightweight build, stainless steel barrel, superb trigger, and surprisingly accurate shooting. Overall, this is the hunting rifle we recommend more frequently than any other.”
VIDEO Two — Tikka T3 Controls and Function
In this video, New Zealander Mitch of BushBrothersNZ reviews a T3 with polymer stock and stainless barrel chambered for the .270 Win. Mitch focuses on the T3’s controls and functions, with particular attention to the operation of trigger, safety, and bolt.
VIDEO Three — Hickok45 Tests Tikka T3X in 6.5 Creedmoor
Popular YouTube gun reviewer Hickok45 reviews the Tikka T3x Tactical Compact Rifle in 6.5 Creedmoor. There are good explanations of the operation of the action and magazine. In addition Hickok45 shoots the rifle offhand (05:10 and 13:44 time-marks), evaluating the ergonomics of the stock and the trigger feel. Hickok45 now has 7.38 million subscribers to his YouTube Channel.
We first ran this story a few years back. But it’s still a very interesting subject for benchrest shooters. Shown above, the 30 BR (a 6mmBR necked up to .30 caliber) currently rules the benchrest-for-score game. However, a 30 BR Improved offers some potential advantages, particularly when the winds are strong or tricky. In this article Al Nyhus explains his 30 BRX wildcat. Running Hodgdon H4198, Al says he gets an easy 150 – 200 FPS more than the conventional 30 BR. That can translate to less drift in the wind. It also lets you pursue a higher speed node, which can lead to improved accuracy with some barrels.
Forum member Al Nyhus is a top-level score shooter who has competed successfully with the 30 BR cartridge in VFS (Varmint for Score) matches. Al has been working on an “improved” 30 BR cartridge that delivers extra velocity. Al’s 30 BRX cartridge is inspired by the 6mm BRX cartridge, popular in 600-yard benchrest and across-the-course competition. The 6mm BRX cartridge maintains the same sidewall profile and shoulder angle as the parent 6mmBR case. Likewise, the 30 BRX retains the 30° shoulder used on the popular 30 BR cartridge.
Al reports: “Thought you might like to see what I’ll be working with in my VFS gun this season. It’s a true 30 BRX — a 30 BR with the shoulder moved forward 0.100″ with the standard BR shoulder angle. Stan Ware of SGR Custom Rifles built one last season for Steve Grosvenor and I was really impressed by the performance of Steve’s gun. The 30 BR barrel on my VFS gun needed replacing, so the new 30 BRX got the nod.”
30 BRX Delivers 150-200 FPS More Velocity than 30 BR
Al says his 30 BRX gives a solid 150-200 fps speed gain over the 30 BR at the top, while needing just 2.5-3.0 more grains of Hodgdon H4198 to do so. A 30 BR case holds on average 40.8 grains of water, while the 30 BRX holds 42.3 grains (roughly 4% more). So the 30 BRX delivers a 7% increase in velocity with a mere 4% increase in H20 capacity. That’s pretty good efficiency. [Editor’s Note: Assuming 34 grains of H4198 is a typical 30 BR match load, Al’s increase of 2.5-3.0 grains for the 30 BRX represents roughly a 7.5-8.5% increase in actual powder burned. That explains the higher velocities.]
Why did Nyhus decide to try an “improved” 30 BR?
Al explains: “The 30 BRX was created to operate at a [higher] velocity level than can be achieved with the standard 30 BR case, while at the same time keeping the easy-tuning characteristics of the standard 30 BR case. We also wanted to use the same powders currently used with the 30 BR and maintain similar operating pressures.” Is the 30BRX harder to shoot because of the increased velocity? Al doesn’t think so: “In a 13.5-lb HV gun, the 30 BRX case is a pleasure to shoot with just a flea bite of recoil.”
Will the 30 BRX Become Popular in Score Competition?
The 30 BR is already an exceptionally accurate cartridge that dominates short-range Benchrest for Score competition. Will the 30 BRX make the standard 30 BR obsolete? Nyhus doesn’t think so. However, Al believes the 30 BRX offers a small but important edge in some situations: “On any given day, it’s the shooter that hits the flags best and makes the fewest mistakes that ends up on top. No amount of velocity will save you when you press the trigger at the wrong time. Missing a switch or angle change at 200 yards that results in 3/4″ of bullet displacement on the target can’t be compensated for with another 200 fps. That’s the hard fact of benchrest shooting. But on those days when, as Randy Robinett says, ‘our brains are working’, the BRX may offer enough of an advantage to turn a close-but-no-cigar 10 into an ‘X’ at 200 yards. Or turn a just-over-the-line 9 into a beggar 10.” Given the fierce competition in Score matches, an extra 10 or another X can make the difference between a podium finish and also-ran status.
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. 
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!
In this video, Gavin builds an impressive 6mmGT (aka 6GT) field rifle start to finish. You can see him chamber the barrel, fit the bottom metal in the stock, and connect the Bix’N Andy trigger to a 416 Stainless Pristine brand Rem 700-footprint action. This is a multi-purpose rifle, build on the light side with a Carbon Six barrel. Gavin notes: “In this video I chamber a Carbon Six barrel and complete the package with a Bix ‘n Andy trigger, Hawkins Rings, and Riton Scope. Will this be the 6GT Lightweight hunting rifle I’ve been asking for?”
CONCLUSION: Stainless steel barrels and components won’t rust nearly as fast as blued steel, but you still have to take precautions — particularly removing sweat and corrosive salts from the barrel. Also, don’t let moisture build up inside or outside of the barrel. We recommend wiping your barrels and actions with Eezox, or Corrosion-X after each use. These are both extremely effective rust-fighters that go on thin, without leaving a greasy residue. (Eezox leaves a clear finish, while Corrosion-X has a slightly waxy finish.) Also store your guns in
