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.

Here’s a handy training option for F-Class shooters. Forum member SleepyGator is an F-Class competitor, but there are no long-distance ranges close to his home. Accordingly, he wanted some “reduced-distance” targets he could use at 300 yards for practice. There IS an official reduced-distanced standard for 300-yard F-Class matches. This utilizes the NRA No. MR-63FC – F-Class Target Center which is pasted over the MR-63 target. It provides a 1.42″ X-Ring, 2.85″ 10-Ring, and 5.85″ Nine-Ring. We offer some free targets you can print out for use at 300 yards. The dimensions of F-Class targets are found in the NRA High Power Rules, Sec. 22, part 4, page 70-71 — see sample below.
To duplicate the 300-yard target, SleepyGator made a printable version of the MR-63FC Target Center, along with a pair of training targets with two bulls and five bulls. The two-bull and five-bull targets mirror the scoring rings on the MR-63FC, but they display only the innermost three rings and two rings respectively. All three targets are Adobe PDF files that can be easily printed.
NOTE: You may need to adjust the scale (sizing) on your printer to get the dimensions exactly correct. As noted above, when printed, the 10-Ring on all three targets should measure 2.85″. This should provide some handy practice targets you can use between matches. Thanks to SleepyGator for providing these targets. You can download all three as a .Zip archive. After downloading the .Zip file, just click on the .Zip archive to extract the individual targets.
Note the owner’s name, “S. Limbourne” was engraved on the bolt release (and trigger guard, see below).
Competition rifles don’t need to be beautiful, as long as they shoot. But who doesn’t like a spectacular figured-wood stock, particularly when it is combined with a superb custom action and a tack-driving barrel. This custom .284 Winchester F-Class Open division rig was crafted by gunsmith Thomas “Speedy” Gonzalez for competitive shooter Scott Limbourne. The handsome Bacote wood stock comes from Cerus Rifleworks, while the action is a polished Borden RBRP BRMXD. Two Brux 1:9″-twist barrels were chambered for the project, both finished at 32″. The stock is also fitted with a R.A.D. Recoil System. This rig has top-of-the-line hardware all around.

For today’s Sunday GunDay story we showcase seven interesting metal-chassis rifles. While we love the look and feel of wood and fiberglass, metal does have its advantages. It can be crafted very straight and true, and the designs can achieve a very low center-of-gravity without sacrificing rigidity. In addition, a precisioned machined metal chassis tends to track extremely well.
Massive IBS Heavy Gun Milled from Solid Aluminum Billet
This remarkable 70-lb IBS Heavy Gun, was machined from solid aluminum billet, by Bruce Baer. It rests on a G&G Alvey rest split in the middle to comply with rules. This “heavy metal” CNC-machined wonder is a work of art designed for the 1000-yard game in the Heavy Gun class. Wood stocks, and to a lesser extent fiberglass stocks, are more forgiving, offering greater damping and recoil absorption. However, metal stocks offer superior rigidity, and the CNC machining allows tracking surfaces to be perfectly parallel.
Williamsport limits Heavy Guns to 100 pounds. Under IBS and NBRSA rules weight is unlimited. You will see a few massive 200-lb behemoths at IBS matches, but most competitors find that something in the 60-90 pound range works best. Bruce Baer explains, “You can’t stop a gun from recoiling. If it doesn’t recoil it will jump. If it jumps you might as well go home because you won’t shoot a good group. So it is pointless to try to build a gun so heavy as to eliminate all recoil. The more you restrict the rifle’s recoil the more temperamental that rifle will be. The 200-pounders just don’t out-perform something in the 60- to 80-pound range, and I think the optimal weight is 60-70 pounds.”
Bruce Baer likes the 70-lb overall weight for a heavy gun: “Extreme mass is not necessarily an advantage. Watch a locomotive starting up from zero–it will vibrate from one end to another. If the gun is too heavy I think it will vibrate at the start of recoil and that will kill accuracy. I want the gun to start from recoil with very little effort so it will be smooth from start to stop.”
Water-Cooled World Record-Setting Wondergun
We like “outside of the box” thinking. And in the world of competitive shooting, it can’t get more unconventional than this. But this radical liquid-cooled benchrest rig wasn’t just a crazy experiment — it actually delivered the goods. This IBS Heavy Gun, built by Joel Pendergraft, produced a superb 10-shot, 3.044″ group that stood as an International Benchrest Shooters (IBS) 1000-Yard Heavy Gun record for seven years, not being broken until 2016.
Using this water-cooled wondergun, Joel shot the record-breaking group in April 2009 at Hawks Ridge, NC. This monster features a .30-Caliber 12-twist, 4-groove Krieger barrel inside a water-filled sleeve (like on a liquid-cooled machine gun). Joel shot BIB 187gr flat-based bullets in Norma brass, pushed by a “generous amount” of Alliant Reloder 25 and Federal 210M primers. The cartridge was a big custom wildcat Joel listed as “.300 Ackley Improved”.
Pendergraft’s 3.044″ 10-shot group was a great feat, breaking one of the longest-standing, 1000-yard IBS World Records. And Joel’s 3.044″ record stood for 7 years!
F1 F-Open Chassis from Competition Machine
Along with his famed tube-guns, Gary Eliseo of Competition Machine has designed a modern, low-profile chassis system for F-Open competition. Assembled with Cerakoted aluminum beams, these F1 F-Open chassis systems offer great tracking with an ultra-low center of gravity.
Here is the F1 Chassis with “Marine Corps Red” powder coat finish. Read Full Report.
This F1 aluminum alloy chassis stock features a super-low center of gravity, plus adjustable length of pull, cheek rest, and drop. The stock is available in a wide choice of Cerakote finishes. The current Model F1 chassis features a action block mounting system to fit most actions. There was also an earlier version that had a free-floated action with the barrel in a barrel block, secured with epoxy. Both F1 versions (action block and barrel block) shot great, with excellent performances in competition.

State Championship Win with Home-Built Aluminum Stock
While most of the stocks featured above were crafted by professionals, the properties of aluminum allow it to be used by persons with some basic mechanical skills and metal-working tools. Here’s proof. Back in 2009, Forum Member John Dunbar (aka JD12) crafted his own aluminum F-Open stock. And he used that impressive metal stock to win the Wisconsin State F-Class championship. READ Full Story.
The stock for John’s “home-built” .284 Winchester was mated with a Savage target action. John designed and fabricated the aluminum stock himself. It features a central barrel block clamping a 32″ Brux barrel. Get this — John completed the rifle only 5 days before the match: “I finished machining/assembly on Monday night, did load workup Wednesday and Thursday nights, loaded rounds Friday night, and headed to Lodi at 4:30 on Saturday morning.” John even made his own co-axial front rest (see below)
Richard King’s Radical .223 Rem F-TR Skeleton Rifle
Here’s something exotic from our Gun of the Week archives. We like this rig because it is so radical (we doubt that you have ever seen anything quite like it). Gun-builder Richard King calls this his “Texas-T”, noting that “this is my personal gun, built the way I wanted it. I know it’s radical and some may not care for it. But it works.” The rig was designed to shoot F-TR, but it can also be converted easily to shoot F-Open with a front rest.
Richard reports: “This is pretty much an all-aluminum rifle. The action is a Kelbly F-Class with a Shilen stainless steel competition trigger. The scope is a 1″-tube Leupold 36X with a Tucker Conversion set in Jewell spherical bearing rings. The .223 barrel is 30″ Pac-Nor 3-groove, 1:6.5″-twist mounted in a V-type barrel block. The bipod has vertical adjustment only via a dovetail slide activated by a stick handle. It works like a joy-stick, but for vertical only. I adjust for windage by moving the rear sandbag.”
Richard likes how the barrel block works: “With the barrel block forward, the vibrations should be at a low frequency. Instead of one long rod whipping, I now have two short rods (barrel halves) being dampened. This is my fourth barrel block gun. They work, but so does a good pillar-bedded action. [This rifle] is designed for my style of shooting. It is not meant to be a universal ‘fit all’ for the general public. However, I will say the design is adaptable. I can easily convert the system to run in F-Open Class. I would drop a big-bore barreled action into the V-block, slide on a heavier pre-zeroed scope and rings, add plates on the sides up front to bring the width to 3″, and maybe a recoil pad.”
When Fiberglass Fails, Aluminum Stock Saves the Day
Australian Mark Fairbairn performed a “Quick Fix” during the 2018 Berger SW Nationals. Mark’s F-Open rifle, in a conventional fiberglass stock, was giving him random vertical during one yardage: “I had a bit of a problem with elevation — the stock was hitting somewhere [causing vertical]. I was X-X-X then a shot popped up in the 9 ring with no good reason. So I figured I better put a new stock on it. I got my old aluminium stock I brought from Australia and quickly adjusted it to fit on the Stolle.”
Right on the firing line berm Mark swapped his barreled action into the metal stock of his own design. The clock was ticking… but the story had a happy ending. For the next yardage Mark shot a brilliant 150-7X, not dropping a point. So the “Quick Fix” did the trick. As they say Down Under — “Good on Ya, Mate!”
Home-Built Aluminum Chassis with Innovative A-Arm Bipod
Here is another home-built rig featuring an aluminum chassis mated to a Savage barreled action via a forward-mounted barrel block. This rig was crafted by Forum member Patrick Lundy, who followed the maxim: “If you can’t buy it, then build it.”
Patrick Lundy was so impressed with a fellow shooter’s barrel-block rifle, that he build a similar match gun himself, complete with barrel block and aluminum chassis. Patrick was inspired by a metal stock belonging to Peter Gagne. But he added his own custom touches, including an innovative “A-Arm”-design bipod for shooting in F-TR class. The gun has been very successful in competition. READ FULL Report
Pat told us: “This new stock was a milestone in my shooting career — it was my very first attempt to build a stock. I wasn’t much of a wood worker but I did have a talent for building with metal. The stock was fabricated from 6061 T6 aluminum. With this gun I was able to shoot from a rest or a bipod.”
Pat crafted the bipod from aluminum tubing: “The bipod was a very rigid A-frame design with welded aluminum tubing. I added slippery feet under the pod skis to facilitate smoother recoil. I realized that a wide-stance bipod had to recoil the same on both sides or the group would string horizontally.” Here is the innovative “A-Arm” bipod that Pat Lundy built for his rifle.

Modern 6BRA Bench Rifle
This handsome benchrest rig belongs to Forum member Tillroot1. It boasts a Kelbly Panda action and a Krieger cut-rifled barrel chambered for the excellent 6BRA wildcat cartridge. The 6BRA is an improved version of the 6mmBR which retains the long neck. The 6BRA is easy to fire-form and very accurate, and can achieve the really good 2950 FPS node with 105-108gr bullets. This cool rig features a Jason Avila-made stock (Wheeler F-Open), with finish work by Brett Childress. Barrel was chambered by Dave Witt.
Bill Goad’s 6PPC Hunter “Ranch Rifle”
Forum member Grimstod tells us: “This is the personal rifle of Bill Goad. He has been experimenting with it on several levels. It is shooting great and has several matches on it now. Please enjoy these photos. More can be found on the website www.PremierAccuracy.com. We like the subtle barbed wire effect on the stock.
Twin-Upper AR with Custom Wood Furniture
This very unique AR belongs to Forum member Nuto-BR. He tells us: “Here are the two uppers I built. The top one is am X-caliber in 20 Practical with 24-inch, 1:11″-twist barrel. The bottom one is a WOA in .223 Rem, with 20″, 1-12″ twist barrel. They both shoot 1/2 MOA or better. Both stocks are laminated Maple and Walnut. I reversed the order of the two woods to tell them apart.”
Two Dashers and a Rimfire for Fun
Courtesy Forum member Dan H., here are two red-stocked Dashers plus an Anschutz 54.30 (Benchrest Stock) to make it a trio. Dan says: “The Anschutz provides good practice in trigger-pulling. It’s amazing what you can learn from a rifle that is as sensitive as this one.”
Dream Hunting Rifle with Custom Camo
Here is Forum member TyDaws’s “Dream Hunting Rifle” in 6.5-280 Ackley Improved. We love the custom paint work by by Melodie Yarbrough. Smithed by West Texas Ordnance, this rifle features a Rem 700 action with fluted bolt, PT&G tapered recoil lug, and Timney 510 2-lb trigger. The barrel is a fluted 26″ 1:8″-twist Bartlein 5R #3 contour. On top is a Huskemaw Blue Diamond 4-16x42mm optic in Warne Maxima rings. That’s an Atlas bipod up front.
Three Guns for Mr. Big
Forum Member Mr. Big offered up another trio of rifles — two bench guns and a tactical rig. Mr. Big says: “Here are the rifles I shoot most: Farley 6mm PPC, Stiller .243 Win, and Rem 6.5×47 Lapua. They will do just about anything I ask them to…” Challenge: Can you identify the makers of the three different stocks shown in this picture (and the different materials used in each)?
Classic M1917 Enfield Action in Hand-Carved Maple Stock
This impressive rifle features an “antique” 1917 Enfield action chambered for the .338 Win Magnum cartridge. The lovely Maple stock was hand-carved by Forum member Spitfire_ER. He tells us: “I found this piece of wood as a return at a lumber yard about [many] years ago. I asked the guy in the yard about it and he said it had been returned because it had too much figure for the job the customer was working on. First thing I thought was, ‘That would make a nice stock’.”
6mm Dasher in Robertson Spider Web Stock
Here is Forum member Vahena’s 6mm Dasher. It has a no-turn-neck chamber in a 28″, 1:8″-twist barrel with 1.25″ straight contour. This has an original Robertson fiberglass stock with spider web graphics. This rifle was originally built as a 6.5×284 with a fluted barrel. Now it sports a bigger barrel for a smaller cartridge. The front rest is a SEB Neo with counterweight up front.
The 2025 European F-Class Championships took place September 1-8, 2025 at the famed NRA Bisley Shooting Centre in the United Kingdom. Hundreds of talented competitors attended the match, with shooters from the USA finishing at the top in both F-Open and F-TR class.
Here’s a report from the NRA UK Facebook Page: “That’s a wrap on the F-Class European Championship. As the biggest F-Class event in the world, it brought together the finest shooters to test their skills at our very own National Shooting Centre, Bisley. It was a true testament to the skill and dedication of every competitor, with Bisley’s Stickledown Range living up to its reputation as a challenging and dynamic range. The wind and conditions were relentless, but so were the competitors.
A huge well done to all the competitors who travelled from across the world to participate. And thank you to the incredible NRA staff and volunteers who made the event possible. We are so proud to have hosted this prestigious event at the National Shooting Centre and we are already looking forward to hosting the World Championships in 2026.”

Heavy Rain and High Winds at Stickledown — Challenging Conditions
There were significant rainstorms during the 2025 F-Class Championship. Competitors needed tough wet-weather gear, and rainguards over their ammo and scoresheets. It was also wise to protect your scopes from moisture so that raindrops did not obscure the lens views.
The 2025 Great Britain F-Class Association (GBFCA) European F-Class Championships take place in the United Kingdom this week from September 2-7, 2025. This match will feature hundreds of F-Open and F-TR competitors. The 2025 “Euros” will be the largest F-Class event ever to be held at the world-famous Stickledown range at the Bisley Camp in the UK, the home of the UK National Rifle Association since 1890. Vihtavuori, Lapua and Berger, known for their world-class reloading powders, brass, ammunition and bullets will be platinum sponsors for the 2025 GBFCA European F-Class Championships.
The Championships are expected to bring more than 400 top shooters (from over 20 countries) to compete in F-TR and F-Open classes. The event consists of both individual and team matches at 800, 900 and 1,000 yard daily aggregates, and Grand Aggregates on Friday and Saturday.
With the ‘Euros’ taking place less than 12 months before the 2026 F-Class World Championships, also at Bisley, the organizers are expecting a very high level of competition. The world’s top shooters are taking this timely opportunity to experience the famous Stickledown range as part of their preparations for 2026.
Conditions were challenging earlier in the week — with heavy rains during the competition. But then the skies cleared, revealing a double rainbow. Photos courtesy March Scopes UK.
The European F-Class Championship event is run by the GB F-Class Association. “We’re really thrilled to extend our partnership with these top brands as main sponsors. Working together to create this successful event strengthens the shooting community and offers great development opportunities for our sport”, said Richard Jones, GBFCA committee Chairman.
“The GBFCA European F-Class Championships is one of the world’s long-range shooting highlights. We’re excited and proud to support this event that brings together the world’s top F-class shooters”, states Vihtavuori, Lapua, and Berger Sales & Marketing Manager Olof Borgstrom.

The 2025 F-Class Nationals took place recently at the Winnequah Range in Wisconsin. The match was run superbly with an excellent target system. Competitor John Masek, who finish 10th in F-Open, noted: “Congrats to all the winners in both Mid and Long Range — there were no ‘gimme’ matches the whole week. It was an awesome match and the folks at Winnequah put on a hell of a match. We had hundreds of devices on the Shotmarker system at one time and I don’t remember it ever going down because of it. Great weather and a tricky tricky range led to all kinds of shake-ups each day especially as long range went on.” The winds did become challenging on the final day said Winnequah staffer Kevin Liebetrau.
The Winnequah Gun Club in Lodi, Wisconsin, hosted the NRA F-Class National Championships from August 2nd to 9th, attracting top-tier competitors. This premier event has two main categories: F-Open and F-TR, each with specific equipment and caliber rules. The championship employed ShotMarker Electronic Target Systems for real-time scoring at both Mid-Range (600 yards) and Long-Range (1000 yards).

Team Lapua’s Keith Trapp won the F-TR division of the USA F-Class Long Range National Championship, with an impressive 1558-58X Aggregate score. This marks Trapp’s second F-Class National Championship win. Trapp won his first F-Class Long Range title in 2022, and his first Mid-Range title in 2023.
“I’m incredibly proud of this win,” said Trapp. “The competition was fierce, but my equipment, particularly the Berger bullets, Vihtavuori powder, and Lapua cases, performed flawlessly, giving me the confidence I needed to perform at my best. It’s truly an honor to win this title for a second time.”
Keith Trapp’s confidence was significantly aided by his choice of ammunition. He relied on Berger 200.20X bullets, propelled by Vihtavuori N150 powder, loaded into Lapua .308 Win Palma cases. Trapp is set to compete this September on the international stage at the upcoming European F-Class Nationals.

Competitor Mike Cateena noted that there was “challenging weather this week for the 2025 US F-Class National Championship and amazingly the rain held off until the finish of the last day.” Mike added: “And congratulations to all the winners and a huge congratulations to the USA F-TR Rifle team — you guys absolutely crushed it at Nationals this year! And thank you Winnequah Gun Club for doing an amazing job at hosting this year’s F-Class Nationals and thank you Criterion Barrels, Inc., Krieger Barrels and Brux Barrels, LLC for supporting the match.”
Competitor F-Class John, who finished 10th in the Long Range event, said the match was run really well and the support services provided to competitors were excellent.
2025 Mid-Range F-Class Nationals Results
The 2025 F-Class Mid-Range Nationals were held August 2-5 at the Winnequah Range. Remarkably, the top five F-Open shooters all finished with 1796 points, dropping only 4 points in nine stages, earning 1796 out of 1800 possible points. Randy Snook won the F-Open Class shooting a 6BRA with a 1796-127X score, winning the title on X-count. Here are the scores for the top five Mid-Range F-0pen shooters: Randy Snook 1796-127X; Brad Johnson 1796-118X; Johnny Ingram 1796-117X; Andy Amber 1796-116X; Dave Lyons 1796-106X.
The top five Mid-Range competitors all finished with 1796 points, dropping just 4 points on 180 targets!
In the F-TR Division (limited to .223 Rem and .308 Win), Gabriel Gavrock secured the 2025 Mid-Range Title with a 1785-100X Score. In second was Lusty Leo Cebula with a 1782-94X score. Finishing third was David Schmidt with 1781-97X. It’s notable that Gabe Gavrock (below left in photo) is just 19 years old — so this is a great start to his marksmanship career. Gabe is a member of the Under-25 United States Rifle Team. He is the only junior to ever win a USA F-Class Nationals event.
Today’s Sunday GunDay article features modern magnum cartridge types favored by F-Open competitors. These cartridges will soon be in the hands of top F-Open shooters.

NRA F-CLASS MID-RANGE NATIONAL CHAMPIONSHIP AUGUST 2-5, 2025
NRA F-CLASS LONG RANGE NATIONAL CHAMPIONSHIP AUGUST 6-9, 2025
Event hosted by Winnequah Gun Club and sponsored by Brux Barrels, Criterion Barrels, Krieger Barrels, and Silver Mountain Target.
There will be two divisions at The F-Class National Championships: F-Open and F-TR. In F-Open the rifles can shoot any cartridge type (up to .35 caliber) and have a 22-lb (10kg) weight limit. A front rest is allowed, and most shooters favor a rest with a joystick control.
In F-TR, two cartridge types are allowed: .223 Remington (5.56×45) or .308 Winchester (7.62×51 NATO), with no restrictions on bullet weight. F-TR rifles are fired off a bipod attached to the rifle’s fore-end. The F-TR weight limit is 8.25 kilograms, or about 18 pounds. This includes the weight of the rifle, scope, and bipod. A sandbag can be used under the rear of the stock. Because of the lower weight limit, which includes the bipod, F-TR stocks tend to be much slimmer and lighter than F-Open stocks which have wide fore-arms to work with the front rests.
F-Open Cartridge Options — Modern Magnum Options
For Today’s Sunday Gunday Story we feature an article about F-Open chamberings by respected rifle builder and past F-Open National Champion Emil Kovan. In this article, Emil reviews some of the new magnum cartridge options that are being employed by F-Open competitors. Many shooters are still using the .284 Winchester (or variants), but an increasing number are shooting 7mm and .30-caliber cartridges based on magnum cartridge types. The 7mm is probably still the favored caliber for F-Open because 7mm bullets offer great ballistics with less recoil than heavier .30-caliber projectiles.
Cartridges for F-Class Part II — Rise of the Magnums
A few seasons back, I wrote an article on cartridge choices for F-Class shooters. CLICK HERE to READ ARTICLE. Since the first article I wrote, F-Class has continued to grow, and push the limits of precision and accuracy. While the .284 Win and its variants are still the most common F-Open cartridges, more and more top F-Open shooters are using magnum cartridge types to win competitions and set new records. In this article, I will list some of the advantages and disadvantages of the most commonly used magnums, and will cover the strengths and weaknesses of each one of them.
Performance factors we will consider for magnum F-Open cartridges include:
1. Equal or better accuracy than standard chambers
2. Better ballistic performance
3. Enhanced case life
4. Barrel life
Accuracy Potential of Magnum Cartridges for F-0pen Competition
John Meyrs has won four National Mid-Range Championships using the .300 WSM. Tim Vought used the same cartridge to win two Mid-Range Nationals and used a 7-6.5 PRC to win the long range Nationals. Standard .437″ case head (.308 Win head size) cartridges still have more Nationals wins overall, but the magnums are quickly catching up, and my prediction is that magnums will dominate soon.
The accuracy and precision potential of magnums used in F-Class (.300 WSM, 7-270 WSM, 7mm RSAUM or “7 SAUM”, 7-6.5 PRC) is better than non-magnum cartridges because their shapes are closer to the ideal “fat/short” body associated with wider nodes and extreme precision. For example a .300 WSM is proportionally much closer to the 6 PPC, 6 Dasher, and 6 BRA than is the .284 Winchester.

The first thing that comes to mind when magnums are discussed is power and speed. In my humble opinion most shooters are missing out on accuracy because they push their magnums right past the most stable and accurate nodes. Recently I met my good friend from the Army Marksmanship Unit, SFC Brandon Green, at a shooting competition. We discussed the latest and greatest in long-range shooting. I knew that the USAMU had switched from 6.5-284 Norma to 7mm RSAUM several years back, but didn’t know what load they are currently using. Brandon told me that the load featured Berger 180gr hybrids in Nosler cases at 2820 fps. We all know that the 7 SAUM is capable of much higher speeds, “but at around 2820 fps the load/rifle combo will hammer the X-Ring anywhere under any conditions” SFC Green said.
F-Open rifles on the firing line at the Ben Avery Shooting Facility in Phoenix, Arizona.
Most shooters jump right into magnum territory velocities when testing, missing out on better precision at standard chamber speeds. For example, my 30 KMR can easily reach 2880 fps with 230gr Hybrids, and it actually shoots pretty good. But the same rifle at around 2770 fps will absolutely hammer the X-Ring in any condition anywhere. When it’s all said and done, F-Class is a long-range shooting competition at a known distance which requires extreme precision and accuracy. It is not a speed race.
IMPORTANT — Case-Head Dimensions Do Make a Difference
Magnums, when shot within reasonable velocities, on average will give better case life due to the bigger case + lower pressure and “more meat” in the case-head area. For example a 7 SAUM case will outlast a .284 Win case when both are loaded to around 2900 fps.
Disadvantages of Magnum F-Open Cartridges
Perhaps the biggest disadvantage linked to magnums is recoil. Some people complain about developing the “gun shy” syndrome after shooting a magnum for a while. Muzzle blast and recoil are significantly more pronounced in magnums, but that can be easily managed with a properly-built rifle equipped with appropriate recoil mitigation hardware such as RAD and the various butt plates.

Barrel Life — “Barrels are Expendable Components”
It is true that certain magnums can torch a barrel in just a few hundred rounds. But the same is true when improving a 6BR to 6 Dasher for example — barrel life might be reduced significantly. More powder = more heat = diminished accuracy after a certain round count. In my experience, a F-Open magnum’s barrel life is very close to high-performance standard cartridges such as the .284 Shehane or .284 KMR. I “retire” my barrels around 1200 rounds regardless of the cartridge being a magnum or not. After that many rounds most barrels will still shoot OK but will copper up, and you will start seeing those unexplained vertical 9s. The bottom line is this, barrels are expendable components very much like brass. You can’t get the performance of .300 WSM and the barrel life of the .308 Win at the same time. If you want to race in NASCAR, fuel mileage should not be the top priority!
Top Magnum Cartridge Types Used in F-Class Open Division
.300 Winchester Short Magnum
The .300 WSM (Winchester Short Magnum) tops the popularity chart in F-Class Open division. It has been used to win numerous National championships and has set many National records. The .300 WSM’s short/fat case shape, with minimal body taper and 35-degree shoulder, contribute greatly to its outstanding performance at long range. Components are readily available as well. Best brass remains to be Norma, although ADG is just as good and some would even say better, but it is more expensive and harder to get at this time.
The .300 WSM has been described as a “super-sized Dasher”.
For the .30-cal magnums, in my opinion, the best bullets by far are made by Berger. If your rifle does not shoot 215gr, 230gr hybrids, or 210gr VLDs well, you likely have a rifle problem, NOT a bullet issue. My “go to” bullet is the Berger 230gr Hybrid. The 215-grainer is a close second, followed by Berger’s accurate but ballistically inferior 210gr VLD, which I use in calm and steady conditions.
Top powders for the .300 WSM are Hodgdon H4831SC and H4350. I know there are many more powders suitable for the .300 WSM cartridge, but none I have used can match Hodgdon’s consistency when shot in different geographical locations and weather conditions.
7mm Remington Short Action Ultra Magnum
The 7mm RSAUM (aka 7 SAUM) used to be the darling of F-Open. Its case capacity and shape are about perfect for launching 180gr pills with great ballistics and precision. Its popularity faded a little, due to the lack of good brass, and the rise of the improved versions of the .284 Win which can almost match the RSAUM performance. Norma still makes 7 RSAUM brass which is pretty good but little on the soft side and hard to find. ADG is arguably producing the best RSAUM brass right now. It is very uniform, reasonably priced, and seems to hold up very well even when pushed hard. The best bullets are again made by Berger, and those are the 180gr hybrid, 184gr hybrid, and 180gr VLD. Best powders are H4831sc, H4350, and Alliant Reloder 16 and Reloder 23.
7-270 WSM, 7-300 WSM, and 7 WSM
The first two are pretty much identical, the only difference being that the 7-270 WSM is necked up .270 WSM while the 7-300 WSM is a .300 WSM necked down to 7mm. I personally prefer the first one since necking-up is easier than necking-down (with fewer doughnut issues).
The WSM case-based 7mms will give you great velocity flexibility as well as superb precision when tuned well. In the 2013 world championship in Raton NM, I was scoring for a gentleman from Canada who was shooting 7-270 WSM. The wind was blowing pretty hard that day. On one of his shots, just before he pulled the trigger the wind gusted. I remember thinking that’s going to be an 8 for sure. The target came up a line 10! I asked him after the match what he was shooting, and he replied 180s at 3100fps. Although capable of such speeds, I think that potentially better and more consistent accuracy can be achieved at much slower speeds. The best powders and bullets are again Hodgdon and Berger respectively. Best cases are made by Norma and ADG, with Winchester being a third option.
7-6.5 PRC — Popular Wildcat
Last but not least on our chart is the 7-6.5 PRC. This particular cartridge is actually a wildcat. It is a 6.5 PRC necked up to 7mm. It is pretty much identical to the 7 RSAUM with the only differences being a shorter neck and .01″-narrower body. Currently the 7-6.5 PRC is the most requested cartridge that I offer when building new rifles. It seems to fill the gap between the .284 Win and the larger magnums very nicely. It is capable of reaching 3000fps but most shooters are getting their best results around 2920-2950 fps. The biggest advantage of this wildcat is brass. Lapua makes super high-quality, readily-available 6.5 PRC brass. Best powders are H4831sc, H4350, Reloder 16, and Vihtavuori VV 555. The best bullet in my opinion is the 180gr Berger. I am yet to hear about a better-performing bullet in this chamber.
Conclusion In conclusion, magnums are not perfect but their performance advantages should be very seriously considered when building a rifle for long-range F-Class. In part three, I will list the most common wildcat magnums, and present the KMR magnums which will make you (if you haven’t already) buy a magnum action and get a magnum build for sure!

Do you have a gun you’d like to see featured there? Register for the Forum and you can add your favorite gun to the list. The photo above shows multiple wood-stocked Palma rifles belonging to Forum member SParker.
We hope these “pride and joy” rifles may provide inspiration for our readers, whetting their appetite for their next competition, varminting, or hunting rifle project.
Team Vihtavuori F-Open Rifle
Here is a state-of-the-art F-Open competition rifle belonging to Team Vihtavuori member Tim Vaught. This features a BAT M action, Alex Wheeler-Avila WFO stock, Bartlein barrels, Bix’N Andy trigger, and March Majesta scope. This ultra-accurate rifle also has a barrel tuner and an adjustable R.A.D. 2A recoil-reducing system. This tames recoil and allows the buttpad to adjust horizontally (fore/aft), adjust vertically, and rotate. Tim lists three chamberings for his F-Open blue beast: 7-6.5 PRC; 7-300 WSM; and 300 WSM.
22 BR Savage Varminter — Accuracy on a Budget
This 22 BR Savage, with upgrades from Sharpshooter Supply, is the “pride and joy” of Forum member Maynard. Note the heavy-contour custom barrel with brake. That 22 BR cartridge is a very effective choice for varmint work, as the ground hog in the photo proves. The 22 BR and 22 Dasher are capable of outstanding accuracy with a large variety of bullets and powders. A 22 Dasher can rival the ballistics of a 6mmBR out to 500+ yards, but with reduced recoil.
Stockmaker’s New 30BR Pride and Joy
This handsome 30BR competition rifle was crafted by its owner, Forum member WillyTP who runs Todd Payseur Stocks in South Carolina. He posted: “Finally found the time to make myself a new stock and get it finished this time. All work from the rooter to the tooter by yours truly.” This score benchrest rifle features top-end components: BAT SV action, BRUX Barrel, Bix’N Andy trigger, and Nightforce 42x44mm scope.
Daughter’s First Rifle — Built by Dad
Above is a nice field rifle built up by a father for his daughter. Forum member FrankZ explains: “This is my favorite rifle and it will become my daughter’s first centerfire. The action is from the first rifle I purchased with my own money 21 years ago (700VSS).” The rifle now sports a 24″ Brux barrel chambered in 6mm Creedmoor, with aftermarket PT&G Bolt and DBM metal.
6BR Ackley Improved from Alex Wheeler
Here is a 6BR Ackley Improved (6BRA) built by Alex Wheeler. This blue marble-painted beauty features a BAT “B” action timed by Alex, fitted with Jewell trigger, and Borden trigger guard. The barrel is a Hawk Hill HV contour finished at 28 inches. The stock is a Deep Creek Tracker with 4″ forearm and rudder system (the toe of the stock adjusts for angle, allowing better tracking). This scope is a Vortex 15-60x52mm Golden Eagle riding in Burris Signature Zee rings.
F-Open Rifle with Borden Action + McMillan Kestros ZR Stock
This state-of-the-art .284 Shehane F-Open rifle belongs to Forum member Willow. This has a McMillan Kestros ZR stock fitted with a RAD (spring-loaded buttpad) system with custom spring. Other components are: Borden BRMXD LBRP DLC-coated action, Bartlein 32″, 4 groove, 1:8.5″-twist 400MOD steel barrel, and TriggerTech Diamond trigger. On top is a March HM 10-60x56mm scope in March Gen 3 rings. Below is a video by Editor F-Class John, showing the features of the Kestros ZR stock.
6BRX in the Country
Forum member Grimstod posted this nice 6BRX in a scenic setting: “Bill Goad at Premier Accuracy crated this fantastic 6BRX. It shoots better then I do.” The rifle features a single-feed Alpin action, with Hart 26″ 1:8″-twist barrel, chambered for the 6BRX (6mmBR wildcat) with .269 neck. Grimstod currently runs 95gr Berger VLDs in Lapua brass. On top is a Leupold 40x45mm scope on a Picatinny rail that Grimstod machined himself. The stock is an HS Precision painted by Premier Accuracy.
6mm Dasher for Benchrest Silhouette Matches
Here’s a gorgeous green 6mm Dasher. Forum Member Gunnermhr states: “This is my new 12-lb Dasher for the 1000 Yard Benchrest silhouette matches. My good friend at CRS Custom Rifle Stocks in Aaronsburg, PA made and painted the stock. It’s similar to a Tooley MBR with a few modifications. It still supported on a 3″ forearm and is full length. Hard to imagine it still makes weight with a wood stock and a 36 power Leopold. Crossed the scale at 11.7lbs. The rifle features a BAT “B” Action. The paint is Candy Apple Green, the forearm has a white base-coat, center section is gray base coat and the buttstock is black base coat, all covered with five coats of clear. It’s the new pride of the fleet as it shoots as good as it looks. This gun hammers with 105gr Berger Hybrids.”
Two Dashers and a Rimfire for Fun
Courtesy Forum member Dan H., here are two red-stocked Dashers plus an Anschutz 54.30 (Benchrest Stock) to make it a trio. Dan says: “The Anschutz provides good practice in trigger-pulling. It’s amazing what you can learn from a rifle that is as sensitive as this one.”
1917 Enfield Upgraded with Hand-Carved Figured Maple Stock
This impressive rifle features an “antique” 1917 Enfield action chambered for the .338 Win Magnum cartridge. The lovely Maple stock was hand-carved by Forum member Spitfire_ER. He tells us: “I found this piece of wood as a return at a lumber yard about 7-8 years ago. I asked the guy in the yard about it and he said it had been returned because it had too much figure for the job the customer was working on. First thing I thought was, ‘That would make a nice stock’.”
