For the very first day of 2026 we present a precision rifle built with a modern 6mm cartridge — the 6GT. Developed by George Gardner of G.A. Precision and Tom Jacobs of Vapor Trail Bullets, the 6GT was designed to have the efficiency of a 6mm Dasher without the need for case forming. It was also designed with a longer case body so it feeds better from magazines. Even with the added capacity, the 6GT is still very efficient, and can achieve good velocities with less powder than a 6mm Creedmoor.
Today’s feature rifle was smithed and tested by Gavin Gear of UltimateReloader.com. Gavin did all the gunsmithing — chambering the barrel, fitting the muzzle brake, and even laser engraving the barrel. In building this 6GT rifle, Gavin used top-tier components: BAT TR action, Krieger 28″ 1:7.5″-twist 4-groove 6mm barrel, TriggerTech Diamond Rem 700-compatible trigger, and Area 419 Hellfire Muzzle Brake. The barreled action was then fitted in a handsome and rugged MDT ACC Chassis. On top is a Zero Tech 4.5-27×50mm FFP Trace Advanced scope in 30mm Hawkins Precision high rings.
We recommend you watch the video above — it covers the rifle build, load development, and then features some remarkable shooting sequences across snowy hills in the Pacific Northwest. Gavin’s team actually used a drone to capture overhead footage of the location.
After developing a promising load with Berger 109gr LRHT bullets, Varget powder, and Alpha brass, Gavin literally headed for the hills to test his new rifle at longer ranges, shooting from bipod. His load had shot well under half-MOA at 100 yards in testing so he was hoping he could hit multiple steel targets positioned at 340 yards, 760 yards, and 1000 yards. Indeed he did, proving the rifle’s great accuracy and Gavin’s fine trigger-pulling skills. You can see the hits at these time points in the above video:
340 Yards — 18:15 time | 760 Yards — 19:00 time | 1000 Yards — 19:54 Time

Building Gavin’s 6GT Precision Rifle
Gavin Gear did all the gunsmithing on this project, using his own Precision Matthews TL-1660 lathe for the chambering with an Alpha carbide 6GT reamer. The barrel work took about four hours total. Shown below is the reamer cutting the chamber, which was finished with a 0.170″ freebore and 0.270″ neck diameter. For other brands of brass you might want the chamber to have a larger 0.272″ neck diameter.

This project when smoothly, with Gavin able to install the barreled action in the MDT Chassis and fit the buttstock in an hour or so. So total build time was about five hours. One nice “finishing touch” on the project was laser engraving the 28″ Krieger barrel — a process you can see in the video below.

About the 6GT — Sort of a 6 Dasher on Steroids
6GT Cartridge Design Features
The 6GT was designed to have an optimal length and capacity for mag-fed PRS/NRL tactical rifles. The 6GT is longer than a 6mmBR and 6 Dasher, but shorter than a 6mm Creedmoor and 6.5×47 Lapua. That gives the 6GT ample case body length to feed reliably from a magazine, while the case capacity is sufficient to run popular powders at reasonable pressures. It has a 35-degree shoulder angle.
On paper the 6GT seemed like the perfect cartridge for PRS- and NRL-style centerfire competition. It has the low recoil of a 6 Dasher, with good feeding and mag compatibility. With the 6GT, a competitor can push 6mm 105gr bullets at 3000+ FPS or run heavier bullets at ~2950 FPS. With this 28″ Krieger barrel, Gavin actually achieved 3004 FPS running 109gr Bergers.
Gavin started with quality Alpha Munitions brass. The cases were then annealed with an AMP Annealer and trimmed to length with a Henderson powered trimmer (see video below). After sizing with a Forster Co-Ax press, Federal SR Primers were seated using a Primal Rights competition seater. Next the powder was measured with an A&D FX120i force restoration scale. Finally, the Berger 109gr LR Hybrid Target bullets were seated with a Forster Micrometer die, again using the smooth Forster Co-Ax press.
Initial Load Testing with Berger and Hornady Projectiles
Before it got cold and snowy, Gavin did load development, shooting from a bench with a Sinclair front rest. The Krieger cut-rifled barrel was accurate right from the start and Hodgdon Varget powder proved to be a very good choice for the 6GT.
Gavin’s 6GT boasts a MDT ACC short action chassis with SRS-X Elite buttstock, vertical grip, and MDT CKYE-POD Bipod.
Gavin did initial load testing with both Hornady 110gr A-Tip Match and Berger 109gr Long Range Hybrid Target bullets. The Berger 109gr LRHT bullets were the most promising. A variety of charge weights were tested, with Gavin settling on 34.6 grains of Varget. This delivered fine accuracy with a 3004 FPS muzzle velocity. Group size measurements with this load are shown in the chart. At 100 yards, four three-shot groups averaged 0.361 MOA, and the rifle produced a nice 0.387 MOA (0.405″) five-shot group.
———————————————— Winter Wonderland for Shooters ———————————————–
We celebrate a New Year when the clock strikes midnight tonight. As 2025 draws to a close, we all hope 2026 will bring happiness and fulfilment. With that spirit, here are six “fun and games” targets. While each requires good conventional marksmanship skills — hitting a small aiming point — there are other strategies involved, such as playing darts or “making change” by hitting the right combination of coins. Most of us started shooting as kids, just plinking for fun. Here’s an opportunity to be like a kid again — to spend a day at the range just having fun with friends and family members.
Dartboard Target with Colored Rings
This printable Dartboard Shooting Target has the numbers inside the outer dartboard ring to allow a larger target. With this target you can shoot for the center bull, or actually play pub-style dart games, aiming for numbers and particular rings. If you don’t know how to play traditional dart games, visit NiceDarts.com for complete darts rules. One popular game is “Around The World”. The object is to hit the numbered zones, starting with number 1. Then you try for 2, 3, and so on. After hitting all the numbers 1 through 20, then hit the bullseye to win. CLICK HERE for Other Dart Board Color combinations.
Slot Machine Jackpot Target
Enjoy a little Las Vegas-style fun on your next trip to the range. This cool Slot Machine Target has four sets of slot machine patterns each with three rows of three symbols. Connect three in a row to win — and hit the Jackpot! This is one of many colorful, free targets available from Targetz.com.
American Coins Target — Make Change
This unique American Coin Target features actual-sized Eisenhower Dollars, Susan B. Anthony Dollars, and Kennedy Half Dollars in the top row. Below are rows of Quarters, Dimes, Nickels, and Pennies in descending order. NOTE: A U.S. Quarter has a diameter of approximately 1 inch, so it’s One MOA at 100 Yards. NOTE: When printing, select “100%” value and landscape mode — NOT “fit to page”! That will keep the dimensions of the coins accurate. Combining math with marksmanship, this target lets kids practice their math skills while having fun. Choose a money amount (such as $2.57 or $3.73), and “make change” by shooting a combination of coins.
NSSF Billiards Table Target
This Billiards Table Target offers 15 brightly-colored numbered balls with the cue ball at the bottom. Aim for the numbers, shooting 1-15 in sequence, or alternate between stripes and solids. You can also draw an “X” on the white cue ball (or attach a paster), and use that to set your zero. This target is fun for shooting outdoors with rifles at 50 or 100 yards or indoors with pistols.
This billiards target is part of a set of 12 Fun Targets from the NSSF. These were issued a couple seasons back for National Shooting Sports Month, held in August of each year. The other free targets include Golf Links, Bowling Pins, Fireworks, Baseball Diamond, Dutch Windmill, Water Balloons, Light Bulbs, Dartboard, and three Bullseye targets.
Flies in Circles Target
Now you can boast to your buddies that you hit a fly on your target — 16 times. On this target, 16 flies with bright red eyes are arranged in a inside circles, 16 to a page. There are various ways to use the fly targets. Some shoot to hit the head only — so aim for those red eyes. There are 11 other variations of this Fly Target available on the Targets.WS website.
Tic-Tac-Toe Fun Game Target
This Tic-Tac-Toe Shooting Game Target lets you challenge your shooting buddies at the range. One player can shoot the red triangles, while the other shoots the white zones, taking turns. You proceed just like a regular Tic-Tac-Toe game, alternating shots, with the goal of getting three of the same color in a row. This is a fun game for a parent and a young family member. You’ll find other fun targets on Targets4free.com.
Special BONUS — AccurateShooter.com Load Development Target
Our Load Development Target has been used by tens of thousands of shooters. It has proven very popular, since all your load data fits neatly in the boxes under each target. In fact this target is being employed by both rifle-makers (Bergara) and barrel-makers (including Criterion) to test their products. The target was designed for aiming efficiency. The red diamonds have 1/2″ sides and you can align your cross-hairs on the horizontal and vertical lines. It is a clean design that is easy to see even at 200 yards with a 20X scope. NOTE: When we test, we usually crank in a little elevation, setting the point-of-impact higher, so our shots fall in the gray circles. That way you leave the red diamonds intact for precise aiming.
The Tikka T3x Ace Target was named the 2026 American Rifleman Golden Bullseye “Rifle of the Year”.
The Tikka T3x ACE Target rifle has been named the 2026 American Rifleman Golden Bullseye Rifle of the Year, a highly coveted award presented annually by NRA Media. This impressive factory rifle is a great choice for PRS/NRL competition. It boast a good chassis with full-length ARCA rail, modular magwell, and adjustable cheekpiece. The action is smooth with a nice fluted bolt and big bolt handle knob. On top of the action is a +20 MOA Picatinny rail which helps with long-range shooting. This rifle has shown very good accuracy with factory ammo, aided by an excellent 2-stage trigger that adjusts from 2 to 4 pounds.
Available chamberings are .223 Rem, 6.5 Creedmoor, and .308 Win with prices starting at $1799.00 at EuroOptic.com. The 6.5 Creedmoor with 26″ barrel would be our choice for PRS/NRL competition.
SPECIAL REPORT: NEW Tikka T3x Ace Target Rifle for PRS/NRL
Tikka is best known for its rugged and accurate hunting rifles. But recently Tikka has introduced an impressive new line of T3x Ace Target chassis rifles. These 10.6-lb rigs have impressive alloy chassis stocks, with modular M-LOK and Arca-Swiss compatible fore-ends, and interchangeable magwells. Optimized for PRS/NRL competition, the Tikka T3x Ace Target has a fine 2-stage adjustable trigger, plus a rear stock section with adjustable cheek-piece and nicely-designed attached lower bag rider. NOTE: Tikka also offers the rimfire .22 LR Tikka T1x Ace Target rifle for practice and competition. This is cool because NRL-22 Matches are now very popular.
Accuracy Testing Results Rifle Shooter, a leading UK gun publication, did extensive accuracy testing of the Tikka T3X Ace Target. This testing is featured in the above video. Shooting from a bench with rear bag and front tripod, the test rifle delivered MOA (or better) accuracy with five out of six types of factory ammo. The best group, 0.68″ for 5 shots, was shot with Lapua ammunition with 167gr Scenar bullets. Here are the test results:
In another test of a Tikka T3X Ace Target, top F-Class shooter Erik Cortina achieved half-MOA or better groups with SAKO 6.5 Creedmoor ammo. Watch Erik shoot the Tikka T3x Ace Target in the video below, starting at 8:22 time-mark.

According to Rifle Ready: “The new Tikka T3X Ace lineup exploded out of SHOT Show 2025 and instantly became one of the most talked-about precision rifles of the year — and for good reason. With multiple testers recording sub-half MOA groups and even extended 15-shot strings under 1 MOA, the Ace is delivering near-custom accuracy right out of the box. Built on the legendary T3C action and paired with a full competition-ready chassis, the Ace Target and Ace Game rifles blend Finnish craftsmanship with modern modularity in a way Tikka fans have waited years for.”
Want to learn more? A Rifle Ready video released this month showcases Tikka T3X features. It covers real-world accuracy tests, reviewer impressions, and the differences between the Target and Game variants. This video does help explain why some shooters say the Ace “beats rifles triple its price”.
In promoting its rifle, Tikka posted: “The T3x Ace Target, crafted with Tikka’s legendary attention to detail, was developed for precision shooters seeking an out-of-the-box competition-ready platform. With its optimized barrel profile, enhanced ergonomics, and refined trigger system, the Ace Target embodies the advanced engineering and shooter-focused design Tikka is known for.” The video below features a test of the .223 Rem variant.
This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame. For best viewing, you may want to change your video settings to 720p or 1080p High Definition and view full-screen (using the video controls).
The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.
In this video, former Army Ranger sniper team leader Ryan Cleckner explains how proper head and scope position is a critical component to accurate shooting. Ryan finds that some shooters place the scope too far forward or too far rearward. If the scope is too far back you may have issues with eye relief and stock reach to shoulder. If it is too far forward, you may have cheek-weld problems or get neck strain. Cleckner cautions: “When you are in a good prone position, you don’t want any strain in your neck muscles or back.”
In the video, Cleckner offers a simple method to check your scope position:
“To see if your scope is set up properly … close your eyes, lay your head on your gun, get completely comfortable, and only when you are set-up, then open your eyes. If you can’t see clearly through your scope, CHANGE something [such as comb height or scope position]”.
“When you open your eyes, if you see some scope shadow [i.e. the black ring around the edge of the scope picture], figure out which way you need to move your head to get rid of that shadow, and then make adjustments to either your position, the rifle, or the scope.”
“Very often you’ll open your eyes and realize you need to move further back or further forward. Instead of moving your position [or head], move the scope and get it set up properly.”
Tip on Viewing Your Reticle:
Cleckner: “Sometimes it can be difficult to focus between the target and the reticle, even with the parallax adjusted properly. I recommend you focus only on the reticle. Just like the front sight on a rifle or a handgun, that reticle is what you can control, and it’s what matters. Focus on a crisp, clear reticle, in a stable platform, and all that’s left is trigger control.”
Long Range Shooting Handbook — A Good Resource Cleckner’s Long Range Shooting Handbook covers a wide range of topics important for precision marksmanship — both shooting skills and technical matters. You can view Sample Chapters from Ryan’s Book on Amazon.com. Cleckner’s book is designed as an intro to key concepts such as MOA vs. Mils, External Ballistics, and Environmental Effects. Included are personal tips and advice based on Cleckner’s years of experience as a sniper instructor and special operations sniper.
The Long Range Shooting Handbook is divided into three main categories: What It Is/How It Works, Fundamentals, and How to Use It. “What It Is/How It Works” covers equipment, terminology, and basic principles. “Fundamentals” covers the theory of long range shooting. “How to Use It” gives practical advice on implementing what you’ve learned, so you can progress as a skilled, long range shooter.
Ryan Cleckner was a special operations sniper (1/75 RGR) and he served as a U.S. Army sniper instructor. Currently he works as a firearms industry executive and practicing firearms attorney.
Yep, it’s wintertime — Christmas is just two weeks away. There is plenty of snow on the ground in many parts of the country. 2025 has brought unusually cold weather to many regions with more snow on its way this weekend. In the Northeastern region, snow storms (with very low temps) are predicted for December 12-15, 2025.
If you plan to go shooting or hunting in the weeks ahead, while the weather is below freezing and snow is on the ground, you need to be prepared. You should always have the right equipment and make sure that you can contact help if something goes wrong (such as not being able to start your vehicle).
The folks at the Precision Rifle Network have created a good video on winter shooting and hunting. Host Marcus Hom provides his TOP 10 TIPS for wintertime shooting/hunting adventures. We recommend that any 4-season shooter watch this video.
TOP 10 TIPS for Winter Shooting and Hunting:
1. Wear Good Sunglasses — With snow on the ground, wearing sunglasses is a must because of the extra reflected light. You can get good sunglasses that also have ANSI Z87.1-approved impact protection.
2. Wear Protective, Moisture-Proof Clothing — Wear a set of Bibs and a long jacket. This will prevent you from getting snow inside your clothing when shooting prone.
3. Take Care of Your Hands — Bring good winter gloves, preferably with a waterproof outer layer. Make sure the inner gloves can work with your trigger/trigger guard.
4. Bring a Good Tripod — A tripod keeps you elevated so you can avoid laying down in snow or slush. That, in turn, avoids body heat loss. “Keeping out of the snow and shooting from an elevated position is pretty important in the wintertime.”
5. Protect Optics and Action — Keep your scope lenses and action clear of moisture, snow, and fog. You will want to have good caps on both lenses. Make sure the action remains closed, and consider some kind of wrap over the action until you’re ready to load and shoot.
6. Ranging Challenges — Laser range-finders don’t perform optimally with intense, bright, ambient light. Also, if it’s showing you may get false readings from snow particles. So take multiple readings to ensure you have the right distance. Also, if you have a reticle with MOA or MIL marks, and you know the size of your target, then you can range the target with the scope.
7. Drop and Windage Info (DOPE) Chart — Bring a waterproof, hard copy dope chart. Out in the field on cold days, a phone battery dies fast, and you’ll want to preserve that battery for emergency phone use if needed. So, you should keep a good old-fashioned drop chart in a waterproof laminate.
8. Muzzle Velocity Issues — Cold temperatures can lower muzzle velocity. Before you go, get an idea of how your velocity will change with low temperatures. Some powders are more sensitive to temperature than others, causing a noticeable reduction in muzzle velocity. A load you’ve worked out in summer may shoot LOW in winter because the actual velocity is low. Even with a “temperature stable” powder you may see a 10 fps slow-down. Do some winter velocity testing if you can before you go.
9. Keep Your Ammo Warm — A simple way to avoid muzzle velocity changes with low ambient temperatures is to keep you ammunition ON YOUR BODY. Have a pouch under your layered clothing where the ammo can be kept relatively warm. See video: 07:50
10. Safeguard Keys and Valuables — Keep keys and valuables in a secure, zippered pocket. “There is nothing worse than losing something… keys, phone, wallet. It’s really hard to find something when its buried under [many] inches of snow”. We also recommend keeping a spare vehicle key hidden on your car/truck. There are magnetic holders that can keep that spare key secure but safely hidden from view.
The National Rifle League (NRL) started off sponsoring major centerfire tactical matches, similar to PRS competitions. That proved successful so the NRL added a .22 LR Rimfire series, called NRL22. The NRL22 rimfire discipline has been a major success, as rimfire guns are fun to shoot and ammo is very affordable. The most popular NRL22 matches have drawn up to 200 rimfire competitors. And now there is a companion rimfire long-range series, NRL22X. Learn more about NRL22 and NRL22X at NRL22.com.
NRL22 offers competition shooting at relatively low expense. There are six (6) classes: Open, Base, Ladies, Young Guns (8-16), Old Guns (OG 60+), and Air Rifle. Base Class is for the budget-minded shooter — the combined MSRP of Rifle and Optic in 2026 may not exceed $1650.00 (so you could spend $950 on a rifle and $700 on a scope for example). That keeps the sport affordable.
Open, Youth, OG, and Ladies Classes have no price limits on rifle and optic. Visit NRL22.com to find an NRL22 match near you. CLICK HERE for the latest set of NRL22 rules (PDF). The NRL also sponsors NRL22X matches. These involve significantly longer distances for greater challenge. Currently, an NRL22 membership costs $60/year for adult classes or $25/year for Young Guns Class.
March 2023 NRL22 Course of Fire
For actual NRL22 competitors, this is a very useful video. It shows how shooting from a variety of positions, and it includes very cool through-the-lens views. This covers the NRL22 March 2023 course of fire.
NRL22 Competition with Base Class ($1200 Max) Rifle
One good thing about NRL22 competition is you don’t need to spend a fortune to compete. Base class is limited to $1200.00 for rifle and optic. You can do very well even at this budget level. This video, complete with through-the-lens imagery, shows an NRL22 match shot with a Base Class Ruger Precision Rimfire rifle.
NRL22 and NRL22X are not just for guys. The ladies enjoy the competition too and do very well. There is a separate Ladies class, but women can also compete in other classes. Photo by Jonathan Ocab.
Interview with NRL22 Founder Travis Ishida
This Vortex Nation video features an 80-minute interview with Travis Ishida, one of the original founders of the NRL22 and NRL22X disciplines. Travis told us that the NRL now runs 7-8 times as many rimfire matches as centerfire matches.
NRL22 Competition Guide — Match Procedures and Equipment
If you want a basic overview about NRL 22 Competition, there is a good NRL22 Competition Guide on the Widener’s website. This covers the classes, the rules, target dimensions, the types of supports used, and match strategies. Here are some samples:
Any rifle system that comes in under a combined MSRP of $1200 shall be eligible to compete in the Base class. This combined MSRP price is for the rifle and scope only. It excludes scope rings and bases, bipods, suppressors, data cardholders, magazines, spare magazine holders, auto bolt releases, aftermarket triggers, and extended magazine releases. Adjustments are also allowed in this division as well as adding rails of any type. If any shooter goes over the MSRP amount of $1200, they get bumped into Open class.
One of the most obvious rules is that all rifles must be chambered in .22 Long Rifle. Magnum and like rimfire cartridges are not allowed. It is recommended that whatever rifle you choose has a removable magazine rather than a fixed, tubular magazine since it’s harder to make safe, but they are allowed.
You can use any equipment in NRL22 unless a specific course of fire rules out using an item specifically. The only exception is tripods are never allowed. The sharing of equipment is allowed as well as slings to assist in unsupported positional shooting.
The steel target dimensions range from .25 inches wide to 6 inches wide. Some stages will require 10 rounds to be shot, while others may have you shoot 12 rounds. Most often, you’ll have 120 seconds to shoot a course of fire.
Ammunition Selection for NRL22 and NRL22X
Our friend F-Class John, a top F-Open competitor, has recently started tactical rimfire matches. He enjoys the challenge. And he admits a big part of the appeal is the MUCH cheaper ammunition. He has seen good results with relatively inexpensive Norma Tac-22 ammo, but he now favors SK ammo which he says offers great performance for the price. In this video, F-Class John tests SK Rifle Match Ammo vs. the premium Lapua Center-X ammo. He tested using a benchrest set-up with his MPA chassis rimfire rifle.

You have probably watched one of the excellent shooting sports videos Ryan Cleckner has done for the NSSF. Ryan’s Understanding Minute of Angle (MOA) video (see below) has been viewed over 3.8 million times! Ryan, a former sniper instructor Ryan who is now an attorney, is noted for his ability to explain complex topics in an easy-to-comprehend manner.
Cleckner has also authored a great book, the Long Range Shooting Handbook, which expands on the topics covered in his popular video series. This book is the #1 Best Seller on Amazon in its category. You can view Sample Chapters from Ryan’s book — just click “Read Sample” on the Amazon product page.
As a long-range shooting expert, Ryan Cleckner has impressive credentials. Cleckner was a special operations sniper (1/75 Rgr) with multiple combat deployments, and he has served a U.S. Army sniper instructor. Currently he works as a firearms industry executive and attorney.
The Long Range Shooting Handbook is divided into three main categories: What It Is/How It Works, Fundamentals, and How to Use It. “What It Is/How It Works” covers equipment, terminology, and basic principles. “Fundamentals” covers the theory of long range shooting. “How to Use It” gives practical advice on implementing what you’ve learned, so you can progress as a skilled, long range shooter.

Iain Harrison, editor of Recoil Magazine, said: “Whether you’re looking to dip a toe into the complex world of long range shooting, or you’re a seasoned shooter with years of trigger time, Ryan Cleckner’s book will prove to be excellent reference material. Well written and easy to understand, it covers all the essential topics that a well-rounded shooter needs to master.”
In this video, Ryan Cleckner reviews proper technique for rifle shooters. A stable platform, sight alignment, sight picture, and trigger control are key fundamentals to shooting properly.
The 6mm GT (aka 6GT) cartridge was conceived as a “bigger Dasher” for PRS and NRL competition. The 6mm GT’s creators wanted 6mm Dasher accuracy and moderate recoil delivered via a cartridge with a slightly longer case body for better mag-feeding, longer neck for seating flexibility, and more moderate pressures. So far the 6GT has performed very well in PRS competition. Today’s story is a bit different — this is about an experiment — running a 6mm GT in an F-TR type rifle. Understand that, under current NRA rules, you may only shoot .223 Rem (5.56×45) or .308 Win (7.62×51), in official, sanctioned F-TR competition, but the 6GT is fine for F-Open. Mike McCasland wanted to see the potential of the cartridge for long-range target shooting, so he put a 6mm GT-chambered Bartlein barrel on a nice custom rifle with McMillan XIT stock and Kelbly F-Class Panda action. The results were impressive.
6mm GT — New Cartridge with Multi-Discipline Potential
Story by Mike McCasland, Texas Precision
The 6mm GT began garnering attention within PRS circles in early 2019. It promised to shoot 105-110gr 6mm bullets at 2950-3000 FPS, yet not suffer from mag-feed issues sometimes found with 6mmBR variants such as the 6 Dasher, 6BRX, and 6BRA. Moreover, since it burned less powder, the 6mm GT promised increased barrel life compared to the 6mm Creedmoor or 6XC. The 6mm GT case size should still work with the accurate powders in the Varget burn-range. I found the 6GT also worked great with H4350.
As someone who aspired to building a repeater and jumping into the PRS game, and had a spare F-TR rifle sitting around, I thought it would be fun to build up a 6mm GT to see if there was any merit to the hype. My smith, Wes Ripley of RIP Precision in Texas, builds a lot of PRS rigs, and already had the reamer on hand (a 0.120″ freebore variant).
Whidden Gunworks had some 6mm GT FL bushing die kits in stock, so I figured why not see what all the fuss was about? At the very least I could play around with the 6mm GT in F-Open Class at local club matches to see how it compared to the 6BRA, 6 Dasher, and other popular 6mm cartridges.

How the Project Got Started with Backup F-TR Rig
My 6mm GT build really started as a project spawned purely from COVID-19 Isolation boredom. This rifle primarily serves as a backup F-TR gun, and it had been relegated to performing some load development on .308 barrels, so I could spin new ones on my main match rifle. The only problem was, I had run out of .308 barrels that needed load development. So, I basically had an ideal test platform just collecting dust in the safe. All I needed was a 6mm GT-chambered barrel, since (like the 6mmBR) the 6mm GT works in a short action with a .308 Win-sized bolt-face.
6mm GT Rifle Specifications:
Action: Kelbly Panda F-Class SA RB/RP
Stock: McMillan XIT with RAD 2A
Barrel: 30″ 5R Bartlein 1:7.5″-Twist, HV Contour
Scope: Vortex Golden Eagle 15-60x52mm
Trigger: Jewell Benchrest, about 2 ounces
Bipod: Phoenix Precision
Mike McCasland reports: “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.”
In this video, George Gardner of GA Precision talks about the 6mm GT cartridge which he helped develop.
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.

On this load development target, all your load data fits neatly in the boxes under each target. The diamonds have 1/2″ sides and you can align your cross-hairs on the horizontal and vertical lines. When we test, we crank in a little elevation, setting the point-of-impact higher. That way our shots fall in the gray circles, leaving the red diamonds intact for precise aiming.

As someone who aspired to building a repeater and jumping into the PRS game, and had a spare F-TR rifle sitting around, I thought it would be fun to build up a 6mm GT to see if there was any merit to the hype. My smith, Wes Ripley of
