For today’s Sunday GunDay story, we feature highlights from two in-depth reports on rifles built around the relatively new 6GT cartridge (also known as the “6mm GT”). Developed by George Gardner (G.A. Precision) and Tom Jacobs (Vapor Trail), the 6GT was designed to feed well from magazines, be more efficient than the 6mm Creedmoor, and offer outstanding accuracy. It is just enough bigger than the 6mmBR or 6 Dasher so it feeds better. But it retains many of the qualities of the 6mmBR (high efficiency and outstanding accuracy). Burning significantly less powder than the 6mm Creedmoor, the 6GT is a bit less expensive to shoot, and should, theoretically at least, deliver better barrel life.
“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
We should say that the 6 Dasher has been used very successfully in PRS/NRL competition, with some aftermarket magazine accessories. For this reason, if you already shoot a 6 Dasher, moving to a 6GT may not be worth the cost of new dies and new brass. A.J. Deysel, writing for LoadDevelopment.com, writes:
“The longer case of the 6mm GT means it feeds as reliably from a magazine as a 6mm Creedmoor, and offers slightly higher powder capacity and in turn velocities than the 6mmBR variants, whilst still being able to use the same accurate and forgiving propellants.
You will also find many competitive and average Joes shooting 6mmBR and 6mm Dashers with a Primal Rights or some other mag conversion kit, having very few if any mag-feed issues at all, so that pretty much also nullifies the need to move away from those [chamberings] if you already own one of those or the reloading equipment for it.” — LoadDevelopment.com
Part I: The 6GT Cartridge for Precision Rifle Competition
Report by Vu Pham
I was ready to build a 6 Dasher when I saw a lot of buzz… about a new caliber George Gardner (Owner of G.A. Precision) and Tom Jacobs (Owner of Vapor Trail Bullets) designed, the 6GT. After some research and talking to George, I ditched the 6mm Dasher build and had GA Precision build me a 6GT on a GAP Templar action I already had in the safe. The reasons to try the 6GT in a new PRS-style rig were as follows:
1. Push a 110-115 grain class bullet at 2880-2930 FPS safely in the Sacramento heat.
2. Achieve a load that is reliable and predictable. The caliber must be easy-to-tune and predictable from barrel to barrel. I don’t want to spend weeks developing a new load each time I spin on a fresh barrel.
3. Be able to run the same mag in all my guns without having to tweak or use mag kits. The round must feed from AICS and AW magazines without major tweaking or hiccups.
4. Get good barrel life. The barrel needs to go 2200-2500 rounds with match-grade reliability and accuracy.
5. Have a competitive cartridge with the least possible recoil without sacrificing too much performance down range, compared to bigger options like the 6mm Creedmoor.
6GT feeding from un-modified magazines has been flawless in all the rifles we tested. The 6GT feeds so well, I sometimes have to do a press check to ensure there is a round in the chamber.
On paper the 6GT seemed like the perfect cartridge for PRS- and NRL-style competition. It 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.
Knowing that I would initially have to make my own 6GT brass and do quite a bit of load development, I enlisted the help of Dan Bertocchini with CS Tactical. Dan has a lot more experience with wildcats and is the man when it comes to this type of data gathering. He has been running a 6 Dasher for a few years so I was curious how he would compare the 6GT to his 6 Dasher.
Quick Summary: “I am really digging the 6GT and the capabilities it offers. It can launch 103gr Vapor Trails at 3000+ FPS or lob heavy 115gr DTACs in the low-to-mid 2900s comfortably. I think we will see this cartridge go mainstream in PRS/NRL-style competition in 2020.” — Vu Pham

Alpha Munitions Pre-Production 6GT Brass George Gardner was kind enough to send us 50 pieces of Pre-Production Alpha 6GT brass for preliminary testing. Like the cases I formed from 6.5×47 Lapua brass, the Alpha 6GT brass will use a small rifle primer. Purchased direct from Alpha Munitions, 6GT brass is now $1.30 per case, which is comparable with Lapua 6mm Creedmoor brass, currently $120.99/100 at Grafs.com.
The major difference between 6.5×47 Lapua-formed brass and Alpha 6GT brass is the case capacity. Alpha 6GT brass has 1.5 to 1.7 grains more case capacity. When a piece of 6.5×47 Lapua brass is formed into a 6GT, the walls of the case now become the shoulder and part of the neck. In a normal piece of brass, the shoulder and neck are typically thinner because of the thickness of the brass tapering from the body to neck.
While the cartridge design was optimized for Hodgdon Varget, the extra case capacity of the Alpha 6GT brass opens the door to Hodgdon H4350 (my favorite powder) and Alliant Reloder 16.
Test Results with Alpha Munitions 6GT Brass
Initial test results were as expected from a premium brass-maker. Dan and I both got excellent Standard Deviations and Extreme Spreads over my MagnetoSpeed V3 and his LabRadar. This string below was with 112gr Barnes Match Burners and 33.8 grains of Varget. Can’t complain about a 3 FPS Extreme Spread!
Yes, H4350 Works with the Alpha Munitions Brass
Personally, I prefer running Alpha 6GT brass with H4350 rather than Varget pushing a heavier bullet. H4350 burns slower and cleaner which should equate to better barrel life. The Lapua-formed 6GT cases just do not have the capacity to reach the cartridge’s full capability with the slower burning powders.
Is the 6GT cartridge accurate? Definitely. Here is a 5-shot group at 600 yards shot by Dan. This was Alpha 6GT brass, with Hodgdon H4350 pushing Barnes 112gr Match Burner bullets.
PART II — 6GT Load Development with Multiple Powders
This text is taken from a full report by Mike McCasland on his 6GT (aka “6mm GT”) bolt action rifle. This rig was designed for general use, not just for PRS/NRL matches. In his 6GT rifle, Mike tested multiple powders including Varget, H4350, Reloder 16, Reloder 15, Shooters World Precision, and Vihtavuori N140. For more details, CLICK HERE for full report.
About the 6mm GT Cartridge
BRASS — The first thing you’ll find is cartridge brass choices for the 6 GT are rather limited currently. At present, the only commercial options are Hornady and Alpha Munitions. For the die-hard Lapua fans, you can technically make 6mm GT brass from 6.5×47 Lapua, however that process is very labor-intensive.
I have used both Hornady and Alpha brass in this rifle and haven’t noticed much difference between the two. I will say that my batch of Alpha brass was slightly softer than Alpha brass I’ve used in other calibers; you could feel a difference when neck turning cases. I’m unsure if that’s a batch issue, or something specific to their 6mm GT brass as a whole. As far as performance, there was little discernable difference. Oddly enough, the Hornady brass seemed to have slightly less case capacity than the Alpha; with most other cartridges it’s the other way around.
POWDERS — The 6mm GT was designed with Hodgdon Varget in mind, and that popular powder works exceedingly well in this platform. That said, the 6mm GT can work with a wide variety of powders, some yielding better performance than Varget.
I’ve tried a multitude of powders during my initial 6mm GT load development: Varget, Shooters World Precision, RL16, VV N140, H4350, and RL-15 to name a few. In my barrel, Hodgdon H4350 seems to deliver the best velocity/accuracy combination. SD and ES also seemed to be the lowest with H4350.
Load Development for the 6mm GT — Many Powders Tested
BULLETS — The most common 0.120″ freebore chamber allows for the majority of high-BC 6mm projectiles found in both F-Class and PRS. I had good luck with the pointed 107gr Sierra Match Kings (SMK), as well as the 110gr Hornady A-Tips in my rifle. For those looking to run the heavier 112-115 grain 6mm offerings, I believe GAP designed a 0.160″ freebore reamer that gets those bullets out of the neck/shoulder junction. Shown below is the 0.120″ freebore JGS reamer print:
SUMMARY — Good Cartridge with Much Potential
Generally speaking, I think the 6mm GT is a good little round. Some may not subscribe to this theory, but I believe some cartridges are inherently easier to tune than others. I’m not sure the 6mm GT is as easy-to-tune as a 6mmBR, 6 Dasher, or 6 BRA, but I don’t think it lags that far behind.
With relatively little trouble, I was able to find loads with both Varget and H4350 that would consistently shoot very well — 0.2 to 0.3 MOA. Moreover, I found the 6GT cartridge lives up to the velocity claims made by G.A. Precision. I was easily able to push the 110gr A-Tips to 2950 FPS, and the 107gr SMKs to low 3000 FPS range without any pressure signs, or unnecessary wear and tear on the brass.
As a fun test, I ran my 6mm GT rifle in a local 1000-yard F-Class match with the 110gr A-Tips, just to see just how well they would perform. Although wind conditions of the day and some E-Target issues prevented my 6mm GT rig from getting the better of the larger 7mm and .30-Cal rifles, the 6mm GT proved itself an accurate little round at distance. Here is a 1000-yard ShotMarker target:
After putting several hundred rounds through my 6mm GT rifle, I anticipate building another 6GT on a repeater action to give PRS a try. I think if you are looking for a dual-purpose rifle that can run tactical matches (with 100% feeding reliability), and can also be used for mid-range, F-Open Class competition, the 6mm GT would be a very good option.

Bushnell Match Pro ED 15×56 Binocular with MRAD Reticle
Bushnell is now shipping its new Match Pro ED 15×56 binoculars, designed for precision and competition rifle shooters. These 15-power, high-magnification binoculars offer ED Prime glass and a proprietary, rotating Shot-Call MRAD reticle. This reticle allows fast shot calls and corrections — something important for PRS/NRL competition. Bushnell says these new 15×56 binoculars, when mounted securely, have “enough power to effectively replace your spotting scope with a wide field-of-view that puts less stress on your eyes and allows you to more easily observe projectile flight.”
Early prototype versions of the Match Pro ED 15×56 binocular have already proved their worth in PRS/NRL competition. Bushnell pro shooter Robert Brantley has used the Match Pro ED binocular in recent PRS matches where he’s won four consecutive Tactical Division titles. In this video, Brantley explains the key features of Bushnell’s 15X, reticle-equipped Match Pro ED binoculars:
“The new Match Pro binos offer the perfect setup for spotting and calling shots on the range,” said Brantley. “They offer … the ability to fine tune corrections with the Shot-Call reticle. It truly does offer the best of everything and I’m not ever going back to shooting without them.”
Two important features of the Match Pro ED binoculars are the Shot-Call reticle and BridgeSet Stabilizer. The offset MRAD reticle is designed for target sizing, ranging and follow-up shot correction. The reticle has a dedicated focus adjustment and can be rotated for leveling after IPD (interpupillary distance) adjustment. Users can lock in their preferred IPD with the integrated bridge-lock, which ensures the binoculars are set for quick use.
This unit has some cool features. The BridgeSet IPD stabilizer provides a barrel angle stop that keeps your inter-pupillary distance constant in the field. A first of its kind, the BridgeSet is like a zero stop for your binoculars. These binoculars also have dual adjustable diopters to keep both barrels perfectly focused. This is important because many folks have slightly different vision in their left vs. their right eyes.
Bushnell’s 15-power Match Pro ED binoculars boast fully multi-coated ED (Extra-Low Dispersion) Prime objective lenses and BaK4 Abbe-Koenig roof prisms with PC3 dielectric phase coatings to ensure 92% light transmission. These Match Pro ED binoculars also feature Bushnell’s EXO-Barrier for high resolution regardless of weather conditions. A rugged magnesium housing protects the internal mechanisms while IPX5 waterproof sealing shields the optics from moisture. Another very good feature is that you can mount a tripod adapter to either the front or rear bridges based on your preference. That’s handy. These binoculars weigh a hefty 56 ounces (3.5 pounds), so you’ll definitely want to mount them on a tripod.
Now in stock, Match Pro ED 15×56 binoculars are currently available for $699.99 at EuroOptic.com and other leading vendors. The Match Pro ED 15×56 binocular is backed by Bushnell’s 20-year Lifetime Ironclad Warranty. CLICK HERE to see full product profile on Bushnell.com.

Are you looking to get started in tactical/practical competitions? Or perhaps you already have have some PRS/NRL experience but want to upgrade your equipment and enhance your match results. Here are eight videos that can help you improve your game. These videos feature top tactical PRS/NRL competitors and George Gardner of G.A. Precision, considered one of the founding fathers of the PRS game. You’ll find other related videos on the Long Range Precision Shooters YouTube channel.
How Accurate Are The World’s Top PRS Shooters?
In this video, MDT put three top centerfire PRS shooters to the test, running them through some of the most difficult stages. The goal? To showcase the level of accuracy and precision these top shooters can achieve. From shooting off barricades to hitting targets from rooftops and rocks, these shooters demonstrate why they are considered among the best in the world.
Cartridge Choice for PRS and Tactical Competition
This video reviews many of the different cartridge options popular for PRS-style competition. The video examines pros and cons of various cartridge choices, focusing on accuracy, recoil, mag-feeding, and value for money. This segment features G.A. Precision owner/founder George Gardner.
Most top PRS shooters are using 6mm cartridges these days. These deliver excellent accuracy with lower recoil and cheaper bullet cost. Popular choices include 6 Dasher, 6 BRA, 6mm Creedmoor, 6XC, and the new 6GT cartridge, which is sort of a stretched version of a 6mmBR. It has a bit more case length for better feeding, and greater case capacity than a 6BR so you can shoot 105-108 grain bullets at 2950 fps with ease. That’s a popular Dasher accuracy node that the 6GT can achieve at somewhat lower pressures.
CLICK HERE for a full write-up on a 6GT rifle build by Mike McCasland (Texas Precision). This includes load development suggestions and a 6GT reamer print. The popular 0.120″ freebore chamber allows for the majority of high-BC 6mm projectiles. Mike had good luck with the pointed 107gr Sierra Match Kings (SMK), as well as the 110gr Hornady A-Tips in his rifle.
PRS Tactical Division — Rifle, Ammo, Optics, and Set-Up
In this video MDT Shooter Matt Stiner explains the basics of competition in the PRS Tactical division. The video covers rifle, cartridge choice, optics, and key accessories. He also explains how to set up your PRS Tactical rig for best results. In addition Matt talks about bullet and brass options.
PRS Ace Shows Skills Barricade Technique — with POV Video
This video features 2015 PRS Champion David Preston shooting the PRS Skills barricade. Dave Preston has been among the best in the nation running this PRS stage. Dave nearly always shoots 100% with the fastest recorded time. In this video you’ll see him successfully nail all eight shots in under 43 seconds. This includes a POV sequence (4:35 time-mark) showing the actual view through Dave’s scope.
The PRS Skills Barricade is an 8-round, 4-position stage featured at most PRS matches. It’s called a “Skills Stage” as it is run the same way at every national match and gives shooters the ability to compare skill levels based on hit percentage and speed. The target is a 10″ plate at 400 yards. There are four different positions, with two shots each. Most people run this stage in about 70 seconds, while Dave does it in the low 40s!
Know Your Limits PRS Stages — Pro Tips
This video showcases how 2018 Oklahoma PPS Champion Clay Blackketter approaches Know Your Limit Stages. With these particular type of stages you have to make judgment calls about your rifle’s accuracy and your ability to hold on target. You can boost your score by shooting the smallest target(s), but you risk losing points if you miss. Clay explains how best to manage a Know Your Limits stage.
PRS on a Budget — Converting a Basic Rifle for PRS Use
Top of the line rifles for competition are exceedingly expensive, but there is another option if you have a rifle in the safe that doesn’t get much use. Top F-Class shooter and wind coach Keith Glasscock notes: “I converted my .223 Remington varmint rifle into a Tactical class/PRS training rifle to save costs on ammunition and barrels so I can get better, faster.” Keith shows a very logical way to get started in the PRS/NRL game.
Bare Minimum: What You Need To PRS/NRL Competition
Like most shooting sports, PRS/NRL precision rifle competition can seem daunting once you start adding up the costs for the rifle, the optic, and all the important gear. We note the maximum price limit for “factory class” has risen steadily over the years, reaching $3000 currently. So even in the least expensive division, you can expect to put out a serious chunk of cash. This month, Dustin Sanchez talks with Brian Whalen about the minimum gear you need to start shooting long range and still be competitive.

Report by Craig Arnzen, Area 419
As the PRS and other tactical/practical competitions continue to grow, a guy tends to wonder, just how good are the top competitors? And what are they actually doing (and viewing) as they complete a stage? Well, a great video from the Long Range Precision Shooters YouTube Channel let us see what the best in the sport see through their scopes when they shoot.
This video features Dave Preston, 2015 National Champion and consistent top performer, shooting the PRS Skills barricade. Dave Preston has been considered among the very best in the nation running this PRS stage. Dave nearly always shoots 100% with the fastest recorded time. In this video you’ll see him successfully engage all eight shots in under 43 seconds — that’s crazy fast. This includes a POV sequence (4:35 time-mark) showing the actual view through Dave’s scope as he completes the stage.
Watch this video! Dave offers excellent advice on gun-handling and body positioning for barricades. Listen to what he says and you WILL shoot better.
This video features the PRS Skills Barricade, an 8-round, 4-position stage featured at the majority of PRS matches throughout country. It’s called a “Skills Stage” as it is run the same way at every national match and gives shooters the ability to compare skill levels based on hit percentage and speed.
The target is a 10″ plate at 400 yards. There are four different positions, with two shots each. Most people run this stage in about 70 seconds, some in the mid-60s, the greats in the high 50s, and Dave does it in the low 40s… mighty impressive!
The Right Gear Aids Stability and Lets You Shoot Faster
Let’s also take a look at two pieces of gear that really helped Dave Preston get stable and shoot fast.
1. BARRICADE BAG — To Get Stable, Really Stable
In the video Dave is using a Solo Sac from Short Action Precision This bag was designed by USMC Solomon Mansalala. It’s a very soft/dense bag and is popular at matches.
The other bag that sees a LOT of use, and is far and away the most used, is the patented Gamechanger Bag from Reasor Precision Solutions and Armageddon Gear.
2. MUZZLE BRAKE — To Make Your Follow-Up Faster
You’ll notice that in the video the rifle is very steady through firing, even though he is not applying a lot of pressure to the rifle. Dave is using a Hellfire Muzzle Brake from Area 419. Combined with the soft-recoiling 6mmBR cartridge he is able to spot his impacts and make adjustments, and can also make very fast follow-up shots as his rifle hasn’t bounced way off target.

PRS Finale Hardware
You’ll find the latest and greatest PRS hardware at the PRS Finale. Notable in recent seasons was the fact that many top competitors moved down from the 6.5/6mm Creedmoor to the smaller, more efficient 6mm Dasher, 6BRA, 6GT and other 6mm cartridges. The 6mm Dasher offers excellent accuracy with less recoil than the 6.5 Creedmoor. New magazine designs allow very reliable feeding with the shorter cartridges.
Allison Zane Takes Top Honors among Lady PRS Competitors

Many hunters and precision rifle competitors use muzzle brakes because these ported devices reduce felt recoil significantly. That make s real difference getting back on target for quick follow-up shots. While many rifle owners appreciate the benefits of muzzle brakes, they may also neglect their brakes, allowing hard carbon and powder residue to build up. Not good. You should regularly clean your muzzle brake to remove fouling and carbon build-up.
As Mark Edgreen posted: “Carbon build up on the crown and in the brake is a recipe for poor accuracy.” And another gunsmith reported that customers complained about guns that “shot out way too early” but they only needed to have the brakes cleaned.
Gunsmith and PRS/NRL competitor Jim See recently reminded his Facebook Fans about the importance of cleaning muzzle brakes: “How many times do I have to say it? You need to maintain your rifles. Clean your muzzle brakes people!”. Jim, who runs Elite Accuracy LLC, notes that hard carbon build-up in brakes can definitely harm accuracy. Look at this example:
Muzzle Brake Cleaning Methods
There are various methods for cleaning a brake, we list a variety of techniques, but we would start with NON-corrosive ultrasound. You’ll want to remove the muzzle device before doing these tasks.
1. Use Ultrasonic Cleaning Machine with cleaning solution. This may be the most efficient method: “I place my brake in the ultrasonic cleaner. Shiney as new.” (Jim Moseley).
2. Spray with commercial Carb Cleaner and brush. Then apply anti-corrosion coating.
3. Soak in half hydrogen peroxide and half vinegar. Suggestion: “Let sit over night and carbon melts off. Brush remaining carbon off, rinse and put the brake back on.” Apply anti-corrosive before mounting.
4. Soak in 50/50 solution of water and white vinegar and brush. (Be sure to apply anti-corrosion coating, such as Eezox, after soaking).
5. Tumble in liquid solution with stainless pins. Comment: “Comes out slightly faded, but perfectly clean on stainless, non-painted brakes though.” Warning — do NOT do this with threaded brakes — tumbling could affect threads of screw-on brakes. Also, tumbling can harm painted or Cerakote finishes.
Gunsmithing Tip: By fitting the muzzle brake so that the barrel crown is slightly forward, it is easier to wipe carbon fouling off the end of the barrel. See photo:

Thinking of getting started in the Practical/Tactical shooting game? Looking for ways to be more stable when shooting from unconventional positions? Then you may want to read Marcus Blanchard’s Practical Shooter’s Guide (A How-To Approach for Unconventional Firing Positions and Training). Unlike almost every “how to shoot” book on the market, Blanchard’s work focuses on the shooting skills and positions you need to succeed in PRS matches and similar tactical competitions.
Blanchard provides clear advice on shooting from barricades, from roof-tops, from steep angles. Blanchard says you need to train for these types of challenges: “I believe the largest factor in the improvement of the average shooter isn’t necessarily the gear; it’s the way the shooter approaches obstacles and how they properly train for them.”
Blanchard also offers good tips on shooting fundamentals. Here’s an example:
Blanchard on Trigger Control
“There will always be some amount of wobble when shooting in positions other than prone, and timing the shot to go off when the reticle is within the target is difficult to accomplish when poor trigger techniques are employed. The most common [mistake] I have seen is ‘slapping’ the trigger. The finger is usually hovering off the trigger, and when the shooter determines that NOW is the time to fire, they quickly pull their finger to the rear and ‘slap’ the trigger. The finger never pulls the trigger in the same place and often provokes a sympathetic contraction of the rest of the muscles in the hand, which results in unwanted movement before the bullet exits the muzzle.”
Author Marcus Blanchard has the credentials. A Marine Corps veteran, Blanchard is a regular Top 10 finisher in Precision Rifle Series events. In 2015 Blanchard was ranked 8th overall (nationwide) in the PRS series at year’s end. In 2016 Blanchard won the New Mexico Precision Rifleman’s Championship.

6.5 Guys Recommend Practical Shooter’s Guide
The 6.5 Guys have reviewed Blanchard’s book and they recommend it highly: “What’s a good book for the beginning shooter who wants to get into long range precision rifle or the intermediate shooter who wants to improve his scores? [The Practical Shooter’s Guide] is particularly useful because it explores firing from various positions and props that are encountered in long range precision rifle [events]. This knowledge is completely missing from more traditional books where the shooter is usually slung up and shooting at a paper target. Marcus… goes into considerable detail about shooting from rooftops, reverse rooftops, side slopes, tank traps, barricades etc. This is the type of information that is very difficult to find. We consider ourselves reasonably knowledgeable shooters and this book provided us with new and useful information.” CLICK HERE for 6.5 Guys REVIEW.
6.5 Guys Review Marcus Blanchard’s Practical Shooter’s Guide
Former USMC scout-sniper Frank Galli explains that there is no voodoo when it comes to precision rifle marksmanship, but there ARE techniques that, when practiced, make the difference between good marksmanship and great marksmanship. Understanding the reasons that a bullet hits or doesn’t hit its intended target at ultra-long distances is a crucial element to learning.
Galli’s explanations of how to understand and compensate for wind speed and direction are excellent. In this book, Galli offers great wind-reading advice.
Published in 2020, Galli’s treatise is four years newer than Blanchard’s book, so it includes more of the latest gear and equipment. Galli’s book covers the fundamentals of precision marksmanship with easy-to-understand methodology. The book follows the same instruction process Galli uses in his live marksmanship classes (CLASS REPORT HERE).
Published in 2020, this well-illustrated, 272-page book covers the latest equipment (scopes, LRFs, chassis systems, magazines, bags, bipods, tripods) favored by tactical competitors in PRS/NRL type matches.

With over 240 shooting-related videos, the Alabama Arsenal YouTube Channel is a remarkable resource. This video channel provides detailed field tests of tactical-type rifles, ARs, and pistols. The testers have access to some very impressive ranges, and many of the tests are far more thorough than you’ll typically find with most gun magazines and gun-centric YouTube channels. For example, Alabama Arsenal (AA) has a series of 1000+ round pistol test videos. These are well worth watching if you are considering purchase of a defensive handgun.
Today we showcase multiple rifle videos covering two centerfire rifles, and three precision rimfire rigs. After these field test videos, you’ll find an interesting technical video which investigates how suppressors can affect muzzle velocity.
Barrett MRAD .300 PRC at 2200 Yards — Extreme Long Range
Here’s a rugged tactical rifle put to the test at Extreme Long Range. This video, featuring a Barrett MRAD chambered for the .300 PRC cartridges, features accuracy testing out to 2200 yards (1.25 miles). There is some good drone footage covering the long path to the target. The shooter noted that the bullets fired from his .300 PRC “go sub-sonic somewhere between 1800 and 1900 yards”, creating additional ballistics challenges at this yardage.
Savage 110 Elite Precision for PRS Production Class
In this video AA’s team reviews the Savage Elite Precision Rifle with MDT ACC Chassis. Retailing for about $1810.00 in 6mm Creedmoor, this is one of the better production class options for PRS and NRL competition. Starting at the 3:10 time-mark, the video shows how all the adjustments function on the MDC ACC Chassis. Guns America Digest did a full review of this rifle, and was quite impressed.
Rimfire .22 LR Bergara B-14R in WOOX Furiosa Hybrid Chassis
Alabama Arsenal recently tested a .22 LR Bergara B-14R rimfire rifle fitted with the WOOX Furiosa hybrid chassis system, an Italian-made product featuring wood sections over a strong aluminum core chassis. The bolt operation and ergonomics of the B-14R simulate a Remington 700 very closely, making this rifle good for rimfire cross-training. The B14-R model tested was the version with carbon-wrapped barrel.
The WOOX Furiosa is an innovative, unique aftermarket replacement chassis. This high-tech hybrid stock/chassis combines wood sections over a full-length, aerospace-grade aluminum skeleton chassis, giving it the “feel” of a wood stock with the strength and stability of a metal stock. We like the way the stock feels on the trigger hand in particular and the smooth wood cheekpiece is also very nice. Made in Italy, the Furiosa is offered in three versions all with wood sections on the forearm, grip area, and cheekpiece. Choose natural Walnut Brown, Micarta Black, or Midnight Grey. Alabama Arsenal tested a B14-R fitted with the Micarta Black version. Below are photos of a centerfire rifle in a WOOX Furiosa hybrid chassis, with the Brown Walnut elements.
CZ 457 Varmint Precision Trainer and Chassis
In this video, Alabama Arsenal compares two higher-end versions of the popular CZ 457 rimfire rifle, a great choice for the NRL22 and PRS 22 disciplines. The test compares the CZ 457 in a Manners composite stock with a CZ 457 version in a Varmint Precision aluminum chassis. Right now basic CZ 457 rifles start at about $540.00, with the Varmint Precision models running $930 for the metal chassis version and $1130 for the Manners carbon-fiber composite stock model.
Informational Video about Rifle and Pistol Suppressors
Alabama Arsenal regularly tests its firearms with suppressors. Over time, the testing team has leaned much about modern sound moderators, comparing features and learning how to install and maintain quality suppressors. Here is an interesting video that shows how suppressors affect shot velocities.

Rifle accuracy is pointless unless you can see your target and aim precisely. That’s why good optics are so important for precision shooting — from 50 yards out to a mile and beyond. Top quality scopes can be very expensive — you’ll see optics costing $3000 or more on many competition F-Class and PRS rifles. Today’s video showcase covers important “Riflescope Knowledge”, including how to adjust for parallax, and how to properly sight-in your scoped rifle. In addition there’s a helpful video defining Minute of Angle (MOA) plus videos showing how to mount optics correctly (and avoid common scope-mounting mistakes).
Rifle Sight-In Process — Start to Finish
Here Ryan Cleckner shares his process for sighting in a scoped rifle. This helpful video covers the full process: bore-sighting, 25-yard shot confirmation, shooting groups, making adjustments at 100 yards, and finding mechanical zero. Looking for more valuable rifle instruction? Then check out Ryan Cleckner’s book, Long Range Shooting Handbook.
How to Adjust for Parallax
Most precision rifle scopes have parallax adjustment, but what is it and why do you need to adjust it? In this Shooting USA video, John Paul of JP Rifles defines parallax and explains why you need to set parallax correctly for the distance to your target. The video then show how to adjust parallax correctly, a process which should start with the scope’s ocular focus.
Understanding Minute of Angle (MOA)
In this video, Ryan Cleckner explains the measurement term “minute of angle” (MOA) and how to use MOA adjustments on your scope to compensate for bullet drop at varying distances. MOA is an angular measurement, used often in long range shooting, that is 1/60th of one degree of a circle. One MOA represents 1.047″ at 100 yards and 10.47″ at 1000 yards. Want to learn more? Read Ryan Cleckner’s article Understand and Using Minute of Angle.
Scope Mounting: Common Scope-Mounting Mistakes To Avoid
Mounting a scope isn’t a super-complex or highly technical job, but there are ways you can mess it up. This Brownells video explains common pitfalls to avoid when you’re mounting a rifle scope.
1. Make sure the rings don’t touch any part of the turret housing, objective bell, or eyepiece. Any one or combination of those will throw off your shot groups big time. Make sure those rings are clamping ONLY the scope’s main tube.
2. Ensure that the scope rings are properly clamped to the scope base. If you can grasp the scope with one hand and the rifle with the other and there’s play between them, your groups are going to be all over the place! Scope rings come with torque specs for a reason.
3. Make sure there’s clearance between the objective bell and the rifle. No part of the scope should touch the rifle itself. The only nexus between the scope and the rifle should be the scope rings — and they’re not actually part of the rifle. This also applies to a removable lens cover. When it’s on the scope, it should not touch any part of the gun.
4. Don’t mount the scope too low on an AR-15. On most rifles, you do want the centerline of the optic as close to the bore as you can get it. But the AR-15’s stock is on almost the same plane as the top of the receiver, so you need some height on the scope. Otherwise, it’ll be too low for you to look through it.
5. Overtightening the scope rings is VERY BAD. You can actually crush the scope tube and damage the optic beyond repair. Stick to those torque specs! If the rings come with a little wrench, that wrench is all you need to tighten them.
How to Sight In a Riflescope — Vortex Tech Talk
This popular video from Vortex Optics explains how to sight-in a rifle so that the reticle is aligned correctly and the scope is zeroed properly for your intended application/discipline. People need to remember that the sight height established by the rings will affect their zero, as the centerline of the scope is above the centerline of the barrel.
Scope Mounting — Proper Alignment and Torque Values
An improperly installed scope can cost you points at a match. In this video, MDT Pro Shooter Keith Baker explains the simple steps required to ensure your scope is secured properly with the reticle aligned correctly. The video centers on a typical Precision Rifle optics installation, but the techniques will also work for hunting, varmint, and benchrest rifles.

This Gun Digest book has become a “go-to” resource for NRL22 and PRS Rimfire shooters. Key topics included in this 2021 Edition full-color Gun Digest book include: rimfire semi-autos and how they work; bolt-action accuracy; match shooting skills; DIY precision gunsmithing; hunting with rimfires; and the future of the rimfire market.
With the growth of rimfire tactical competition, the .22-Caliber rimfire rifle is more popular than ever. Every major gun manufacturer has brought at least one new .22 LR rimfire rifle to the market in the last two years. Gun Digest’s Rimfire Revolution has extensive coverage of new models from major manufacturers.
The .22 Long Rifle (.22 LR) is the planet’s most popular ammunition type and firearm chambering. The .22 LR is used in the Olympics by 3P marksmen, but it also serves benchrest competitors, NRL22 shooters, backyard plinkers, small-game hunters, and tactical trainers. With the expansion of NRL22 matches (and the PRS equivalent), the humble .22 LR is undergoing a major resurgence in the USA. And with centerfire reloading components being so costly and difficult to find, many folks are shooting less centerfire, but way more rimfire.
This 272-page book also covers .17-caliber rimfire cartridges: 17 HM2 (Mach 2), 17 HMR, and 17 WSM. These are all excellent varmint rounds, with the 17 WSM effective out to 250 yards. The 17 HM2 will run in a normal .22 LR action and feed from standard .22 LR magazines. So, for most rifles, all you need to do a .22 LR to 17 HM2 conversion is a barrel switch. That gives your rimfire rig twice the versatility. Shoot .22s and .17s with the same gun.
NRL22 — Challenging Practical Competition with .22 LR Rifles
The USA has seen a big growth in rimfire tactical matches over the last five years. Right now there are probably ten times as many rimfire tactical matches as sanctioned PRS and NRL centerfire matches. The reason is simple — rimfire ammo is much less costly, and clubs can run challenging rimfire tactical matches at nearly any outdoor gun range that allows shooting out to 200+ yards.
NRL22 Competition — Tactical Rimfire Matches
The NRL22 match format is a great shooting discipline. NRL22 offers a high fun factor at relatively low cost. You don’t have to reload match ammo. A couple of 50-round boxes of .22 LR ammo will get you through the match. While some people bring lots of gear to matches, that’s by choice and not by necessity. You can keep it simple and still be competitive (and win).
Tips for NRL22 Competitors by Jonathan Ocab
I am a match director at my gun club and run our local NRL22 matches. People often ask me for tips for competing in NRL22. First, I recommend getting the course of fire for the month in advance and practicing those stages at the range. Here are other specific tips that should help NRL22 competitors improve their gun-handling and match results.
1. Dry Fire Practice — If you are not able to do live fire practice at the range, I encourage shooters to practice their shooting positions at home via dry fire. Setup props or barricades with pasters or other faux targets on a wall in the garage or inside the house and run through each stage.
2. Scope Magnification Level — The most common issue I see with newer shooters in NRL22 is the tendency to maximize their scope magnification. The timer will start, and the shooter gets into position on a target, but the scope is set to 15x or higher and the shooter can’t find the target. The shooter lowers the magnification, locates the target, and then increases the magnification again, takes the shot, transitions to another target, and repeats the process of decreasing magnification, locating target, etc. Novice NRL22 shooters should try using the mid-range magnification. Try shooting 7x-12x and learn to balance field of view and target image.

Rifleshooter.com does some great original research — providing “hard data” you can’t find anywhere else. Here are the eye-opening results of Rifleshooter.com’s 6.5 Creedmoor barrel cut-down test. You may be surprised at the results. Read on…
What do you get when you cut a 6.5 Creedmoor-chambered barrel down to just over 16 inches? A lot more velocity than you might think. Our friends at Rifleshooter.com conducted a remarkable barrel cut-down test with 6.5 Creedmoor test rifle, shortening the barrel from 27 to 16.1 inches in one-inch increments. Surprisingly, with a 142gr Sierra MK, the total velocity loss (as measured with a Magnetospeed) was just 158 FPS, an average of 14.4 FPS per inch of barrel length. With the lighter 120gr A-Max bullet, the total velocity loss was 233 FPS, or 21.8 FPS average loss per inch of barrel.
Test Procedure
Five (5) rounds of each type of cartridge were fired at each barrel length and the velocity data was recorded with a MagnetoSpeed V3 barrel-mounted chronograph. The rifle was then cleared and the barrel was cut back one inch at a time from 27″ to just over 16″. NOTE: During this winter test, the air temperature was a very chilly 23° F. One would expect higher velocities across the board had the outside temperature been higher.
The photo below shows how the barrel was cut down, inch-by-inch, using a rotary saw. The barrel was pre-scored at inch intervals. As the main purpose of the test was to measure velocity (not accuracy) the testers did not attempt to create perfect crowns.
6.5 Creedmoor vs. Other Mid-Sized 6.5mm Cartridges
The 6.5 Creedmoor is a very popular cartridge with the tactical and PRS crowd. This mid-size cartridge offers good ballistics, with less recoil than a .308 Winchester. There’s an excellent selection of 6.5mm bullets, and many good powder choices for this cartridge. When compared to the very accurate 6.5×47 Lapua cartridge, the 6.5 Creedmoor offers similar performance with less expensive brass. For a tactical shooter who must sometimes leave brass on the ground, brass cost is a factor to consider. Here’s a selection of various 6.5mm mid-sized cartridges. Left to right are: 6.5 Grendel, 6.5×47 Lapua, 6.5 Creedmoor with 120gr A-Max, 6.5 Creedmoor with 142gr Sierra MK, and .260 Remington.
When asked to compare the 6.5 Creedmoor to the 6.5×47 Lapua, Rifleshooter.com’s editor stated: “If you don’t hand load, or are new to precision rifle shooting, get a 6.5 Creedmoor. If you shoot a lot, reload, have more disposable income, and like more esoteric cartridges, get a 6.5×47 Lapua. I am a big fan of the 6.5×47 Lapua. In my personal experience, the 6.5×47 Lapua seems to be slightly more accurate than the 6.5 Creedmoor. I attribute this to the quality of Lapua brass.” Now that Lapua offers 6.5 Creedmoor brass with small primer pockets, the 6.5 Creedmoor is even more attractive.
The creator of Rifleshooter.com also operates a Custom Rifle Building enterprise and gun shop in Long Island, New York: 782 Custom Guns Ltd.. He tells us: “We offer an unparalleled level of gunsmith machine shop services in the Long Island region. From precision rifles (USMC M40A3/A5/A6 XM3 clones) to customized Remington 870 and Mossberg 590 shotguns, and customized 1911s, chances are if you can dream it, we can build it!”

For years we have touted the advantages of Burris Signature rings, with polymer Pos-Align Inserts. PRS/NRL shooters take note — this technology is available in a beefier, heavy-duty ring system for tactical rifles. The impressive Burris XTR Signature Rings offer six (6) clamping bolts per ring plus strong, dual steel base-clamps that self-center on Weaver or Picatinny rails. These aluminum XTR Signature Rings provide strength and holding power, plus the key benefits of Pos-Align inserts. As impressive as XTR rings are — they aren’t that expensive, with 1″-diameter XTRs starting at about $90.00 per pair (30mm and 34mm XTRs cost a bit more).
The polymer inserts in Signature rings perform three key functions. First, the inserts provide full, uniform scope-to-ring contact, with no need for lapping. You get a very secure “grip” on your scope without ring marks. Second, the Pos-Align inserts can provide elevation “pre-load”. With eccentric (offset) inserts, you can raise the back of the scope relative to the front, gaining up to 54 MOA of built-in elevation, without the need for expensive tapered bases. Third, the offset inserts can be rotated clockwise or counter-clockwise to shift point of impact. This lets you zero your rifle easily while keeping the turrets in the center of their travel.
Burris XTR Signature Rings are offered in 1″, 30mm, and 34mm diameters, and three (3) different heights: 1″, 1.25″, and 1.5″. Each ring set includes two sets of concentric inserts and one set each of the following offset inserts: +/-5 MOA, +/-10 MOA, +/-20 MOA. These allow you to “pre-load” elevation and/or center up your cross-hairs.
– Pre-load Elevation. No need for expensive tapered bases for long-range shooting.
– Correct misalignment caused by off-center receiver holes.
– Correct for bases or rings being slightly off-center.
How to Pre-load Elevation
To add elevation, set the Pos-Align Offset Inserts to raise the rear of the scope and lower the front. As long as there remains sufficient clearance between the front objective bell and the barrel, Burris recommends lowering the front of the scope the most and raising the rear of the scope the least. The amount of actual elevation “pre-load” will depend on the ring spacing (see chart). In the illustration, with 4.75 inches between ring centers, a +/- 20 MOA pair in the front combined with a -/+ 5 MOA pair in the rear will yield +25 MOA of total elevation. (If the rings are positioned further apart, you’ll get less elevation pre-load.)
Using Inserts to Adjust Point of Impact in Any Direction
Although it is convenient and most understandable to refer to the ring inserts as a “bottom” or “top” insert, the inserts may be rotated to any angle within the scope rings. This allows the shooter to correct the point-of-impact in any direction. The drawings below show how the inserts can be rotated to induce both elevation and windage changes at the same time.

George Gardner was kind enough to send us 50 pieces of Pre-Production Alpha 6GT brass for preliminary testing. Like the cases I formed from 6.5×47 Lapua brass, the Alpha 6GT brass will use a small rifle primer. Purchased direct from Alpha Munitions, 6GT brass is now $1.30 per case, which is comparable with Lapua 6mm Creedmoor brass, currently $120.99/100 at Grafs.com.
BRASS — The first thing you’ll find is cartridge brass choices for the 6 GT are rather limited currently. At present, the only commercial options are Hornady and Alpha Munitions. For the die-hard Lapua fans, you can technically make 6mm GT brass from 6.5×47 Lapua, however that process is very labor-intensive.
