One recent trend in F-TR competition is the use of low-profile, benchrest-type stocks shot with a light hand-hold and little or no face contact. For this method of F-TR shooting to work, you need the right equipment, and practice a “minimalist” shooting technique. One of the pioneers in this style of F-TR shooting is action-maker John Pierce of Pierce Engineering. Above you can see John shooting one of his F-TR rifles at the 2015 Canadian F-Class Championships. Note the straight-line stock and see how the adjustable bipod is set quite low to the ground (in fact the bipod’s arms are almost straight out).
Members of the Michigan F-TR Team, including Bryan Litz, have used similar rigs with success. Bryan said it took a while to adapt his shooting technique to this kind of rig, but there is a pay-off. Armed with a Pierce-built F-TR rifle, Bryan won his first-ever F-TR Match. Bryan explains the technique he uses when shooting this kind of rifle:
“Coming over from sling shooting, I knew there would be unique challenges to F-TR which I wanted to learn prior to (not during) a major tournament. I learned a new shooting position which doesn’t involve drawing the right knee up. For F-TR I get more straight behind the gun rather than at an angle. I found that the rifle shoots best with very light cheek, shoulder and grip pressure, approaching free recoil. This is how Eric Stecker shot his similar rifle into second place in the SW Nationals [with high X-Count by a large margin]. I learned the rifle’s sensitivity to different bipod and rear bag supports, and found the best buttplate position to allow the rifle to track and stay on target after recoil. This set-up shot best with a mostly free-recoil approach, that means ‘hovering’ over the comb, rather than resting your head on the stock. This took some ‘getting used to’ in terms of neck and back muscle tone. These are the kind of details I think it’s important to focus on when entering a new discipline.”
Bryan’s Pierce-built F-TR rig is a tack-driver: “I can certainly vouch for this set-up! In [a 2015] mid-range State Championship in Midland, MI, I shot my Pierce rifle into first place with a 598-44X (20 shots at 300, 500 and 600). Once you get used to the positioning and way of shooting these rifles, they just pour shots through the center of the target.”
Pierce F-TR Rifles with Scoville Stocks
Shown below are three complete Pierce F-TR rifles, along with a barreled action for comparison. The carbon-fiber/composite stocks are built by Bob Scoville. These Scoville stocks are very light, yet very strong and very stiff.
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.

About the 6mm GT Cartridge
BRASS — The first thing you’ll find is cartridge brass choices for the 6mmGT 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.

A multi-time F-TR National Champion, James “Jimmy” Crofts is one of America’s top F-Class competitors. And now this F-TR ace has a stunning new rifle in his arsenal. AccurateShooter Forum member CigarCop, head honcho of KW Precision LLC, recently completed a new F-TR rig for Crofts. This handsome, state-of-the-art rifle features top-tier components: Borden action, twin Brux barrels, Cerus RifleWorks F-TR Stock, and Jewell trigger, all resting on a wide-base Phoenix Bipod.

Have a good look at these photos below. Yes, envy is the appropriate reaction. With the smooth operation of the Borden action and the predictable accuracy of Brux barrels, we bet James’s new rig will shoot as good as it looks.
CigarCop actually chambered two barrels for James, with different fluting patterns — conventional linear flutes for one tube, and lines of staggered ovals for the other. Finished length for both barrels is 30″. Yes it looks cool, but the fluting was done mainly to save weight with the 30″-long lengths. CigarCop tells us the complete rifle, without scope and rings, weighs just under 15 pounds. Max allowed weight for an F-TR rifle, with scope, is 18.18 pounds (8.25 kg).
When James Crofts is not shooting his .308 Win F-TR rig,
he often trains with a .22 LR Rimfire rifle. Read on…
Rimfire Training for F-Class Competitors
2014 and 2012 U.S. National F-TR Champion James Crofts is one of America’s top F-Class shooters. A member of 2013 World Championship-winning F-TR Team USA squad, James knows a thing or two about long-range shooting. But you may be surprised to learn how James sharpens his shooting skills at relatively short distances. You see, James often practices with a .22 LR rimfire rifle at distances from 50 to 200 yards. James tells us: “Shooting my F-Class rimfire trainer saves me money and improves my shot process and wind-reading abilities.”

Rimfire Training Teaches Wind-Reading Skillsby James Crofts
Training with the rimfire is extremely useful and can be done from 25 yards out to 200 yards. I am lucky and can shoot 50 yards right off my back deck. That is far enough that any miscue on rifle handling will show up on the target. I use a two dry-fire to one actual shot routine for my practices. This gives me much more positive reinforcement without any negative reinforcement.
Wind reading is extremely important with a .22 LR rifle. I use a set of smallbore flags to aid my wind calls. The smallbore flags are a must and force you to look at the flags and mirage on each and every shot.
This Rimfire rifle features a CMP-sourced Rem 40X barreled action, PR&T Low Boy stock, Jewell trigger, and Phoenix bipod. The gun was built by Ray Bowman of Precision Rifle & Tool. James Crofts told us: “The project turned out awesome — the rifle was a hammer from the beginning even with the stock barrel.”
Rimfire Training Is Cost-Effective
Rimfire ammunition is much less costly than centerfire ammo. Though .22 LR prices have risen, you can still get a 500-round brick of very good .22 LR match ammo for around $75.00. That works out to fifteen cents a round. That’s a fraction of the cost of handloading .308 Win match ammo. The top match-grade, .308-cal centerfire bullets can cost around $60 per hundred. Then you have to figure in brass, primers, and powder. Finally you have to consider your precious centerfire barrel life lost to practice.
The best F-Class and Sling shooters in the nation compete each year at the Berger Southwest Nationals at the Ben Avery range in Arizona. Walk down the firing line and you’ll see the absolute “best of the best” in equipment — from $3500 optics to $2000 stocks and $400 triggers. Berger SWN shooters have some of the best equipment you can buy. In this game, where just 1 or 2 points can separate first from third place (considering X-Count), it’s important to have top-flight equipment. That means a custom action, custom barrel, and high-end stock or chassis system.
Matt Schwartzkopf, a range supervisor at Ben Avery, and member of the USA F-TR Team, has collected comprehensive gear reports from the 2020 Berger SW Nationals. Matt has created charts showing competitors’ choices for Actions, Barrels, Stocks, Riflescopes and Spotting Scopes. In addition, Matt has compiled bullet choice data for all classes and Cartridge rankings for F-Open Division.
There is a discussion of the 2020 SWN Gear Selection in our Shooters’ Forum. CLICK HERE to follow that Forum thread. Many top SWN shooters, including past F-Open National Champion Larry Bartholome, have contributed to this Forum discussion about gear options.

Cartridge Selection in F-Open Division
In addition, Matt produced an interesting listing of cartridge/caliber types for the F-Open division. This is helpful because cartridge choice is unrestricted in the F-Open class. By contrast, the F-TR division is limited to .223 Remington (5.56×45) or .308 Winchester (7.62×51). You can see that the .284 Winchester (and variants) currently dominate F-Open.
A while back, our friend Vince Bottomley in the UK wrote an excellent article for Target Shooter Magazine. Vince offers “solid-gold” advice for new F-TR and F-Open shooters. Vince reviews the cartridge options, and offers suggestions for a shooter’s first (and hopefully affordable) F-Class rifle. Vince also reviews various bipod choices for F-TR and discusses optics options (from $300 to $3000).
Getting Started in F-Class by Vince Bottomley
As membership secretary of a large club, one of the questions I’m frequently asked – “What’s the best way to get started in F-Class?” My club has an F-Class shoot every couple of weeks at ranges from 300 to 1000 yards and, not surprisingly, it’s very popular.
F-TR or Open Class?
From a shaky start way back in 2004, the F-TR Class is now proving as popular as Open Class and, at GBFCA League shoots and club shoots, many shooters choose to start with a 308, shooting off a bi-pod – in other words F-TR. In Open Class, the 7mm WSM soon established itself as the “must have” cartridge – if you wanted to win but, the WSM’s appetite for barrels eventually brought another 7mm cartridge into play – the 284 Winchester. This 50-year-old stalwart was revived a decade or so ago as the 6.5-284 and indeed this cartridge found some favor with F-Class pioneers – before the potency of the WSM was discovered. If you don’t mind shelling out for a couple of barrels per year (barrel life is about 750 rounds with the WSM) go for the 7mm WSM but, if you require a decent round-count, then opt for the .284 Win and learn to read the wind a bit better!
Scopes for F-Class
If you will be shooting 1000 yards then I would recommend at least 32 power and preferably a variable – like the 8-32. The cheapest “usable” scope in this range is the Sightron. It’s a great scope for the money and at under $900 (in the USA) it’s half the price of its nearest competitor. It’s also light – at 1.5 lbs – and there are some great reticles for the F-Class shooter – like the LRMOA.
F-Class shooting (both F-Open and F-TR) is one of the fastest-growing forms of rifle competition. Each season many new shooters hit the line and attendance at the major F-Class matches increases every year. But if you’re new to the game, you may ask “Where can I shoot an F-Class match?”. Well, Forum member Rod V. (aka Nodak7mm) has compiled a useful list of 112 ranges throughout the USA where F-Class matches are held. With venues from Alabama to Wyoming — you should find an F-Class program not too far from home. The list, in Excel spreadsheet format, provides range locations and weblinks (where available). Click the link below to download the F-Class Range List (.xls file):
Note — this list, now in its 20th Revision, is augmented regularly, but info is still being gathered. No claim is made that the list is comprehensive. But it still covers the the lion’s share of the important F-Class venues nationwide. If you know of a range that should be added to the list, please post the location on our F-Class Range List Forum thread. Rod will update the list as new range info is received. Rod writes: “Range information is wanted and welcomed. I would like your help on collecting specific info on Clubs/Ranges where known F-Class matches are held.” Here’s a partial sample from Rod’s list:
The 2020 Berger Southwest Nationals are complete. As expected, it was a hugely successful match that challenged the nation’s top Sling and F-Class shooters. We want to praise all the competitors and congratulate the 2020 SWN Champions in all three classes. The competition was fierce through-out the match. John Whidden won the Sling Division with a 1245-75X score, just one point ahead of runner-up Oliver Milanovic (1244-72X). Bobby Gill was third with 1240-58X.
In the F-TR Division, Peter Johns had a dominant performance with 1242-58X, twelve points ahead of second-place Wade Fillingame (1230-50X) and third-place Ian Klemm (1230-46X). Ian also shot on the winning USA Independence F-TR Team.
Jay Christopherson Wins F-Open
We cheered the F-Open news. AccurateShooter’s own Jay Christopherson, our Systems Administrator, took the 2020 F-Open title with a brilliant 1247-83X score, 11 “Xs” ahead of runner-up Pat Scully (1247-72X). In third place was Tod Hendricks (1245-81X). Jay (photo right) was shooting a Brux-barreled straight .284 Win with Berger 180gr Hybrid bullets. Up front he uses a SEB Mini coaxial tripod rest. Jay also helped carry Team Lapua-Brux-Borden to an F-Open Team victory. Here’s a short video of Jay shooting when he finished second in F-Open division at the SWN a couple seasons back. You can view Jay’s smooth gun-handling and patience waiting for his condition:
Jay Christopherson, AccurateShooter.com’s System Admin, won the F-Open division. Jay’s Brux-barreled .284 Win was superbly accurate all week long. This video was from a past Berger SWN Event.
John Whidden of Whidden Gunworks won Sling division with a 1245-75X score. John really likes this match: “For most of us it’s the first match of the year, a chance to shake off the cobwebs.” John said conditions were “pretty nice on Friday, Saturday and Sunday — most of the changes came slow and conditions were readable from the mirage.” John, a 5-time National Long Range Champion, is always a threat to win at the SWN. John shot a .308 Win in the Palma Class, and then his .243 Win in the Any Rifle division. Both with Berger bullets and Vihtavuori powders. Here’s John at Ben Avery in 2018:
Above is Peter Johns, F-TR Class winner. Peter posted: “I just accomplished one of my goals of winning a national-level F-Class shooting match! I was only able to do with the support of my wife and family. Also I would like to thank Alonzo Custom Rifles for building a great shooting rifle, Kelly McMillan for the best rifle stock for F-TR (Kestros BR) and Vortex for the best riflecope (Golden Eagle) for F-Class.”
Top SWN Team Performances
A new team record was set at Ben Avery this year. In the F-TR Division, Team USA Independence finished with a 2563-113X score. We are told this is the highest-ever F-TR score. Congratulations to Top Scorer Ian Klemm (645-28X) and the other shooters Wade Fillingame, Fritz Braun, and Luke Ramsey. Keith Trap coached and Kent Reeve was Captain.
In F-Open Team Lapua-Brux-Borden continued its dominance, with a fine performance on the final day. The Team finished at 2584-160X, six points ahead of runner-up Team McMillan F-Open (2578-135X).

Emil Praslick III of Capstone Precision Group offered this perspective on the 2020 Berger SW Nationals: “Wrapping up the Southwest Nationals which was amazingly well run by the Desert Sharpshooters. Matthew Schwartzkopf, Michelle Gallagher, Nancy Tompkins, Melesia Cisneros, Scott Fulmer, Mid Tompkins, and everyone else behind the scenes literally work for at least six months to make the event the well-oiled machine that it is.
Moving and managing close to 400 shooters is a Herculean task, and anyone who thinks they can do better should… offer to come down to help out. I shot awful, but it was a pleasure to see the joy of the shooters as they experienced this one-of-a-kind match. Imagine cooking Thanksgiving dinner for 400 relatives with individual dietary needs on a motel hot plate, and you’ll get an idea of the scale involved. Again, thank you Matt and the gang, and we’ll see you next year!”
Emil Kovan is one of the top F-Class shooters in the world. He won the 2014 United States F-Open Championship, and finished second in F-Open Division at the 2016 Canadian National F-Class Championship in Ontario. He is a great shooter and a great gun-builder as well.
“What are the best components for an F-Open class rifle, and why?” That’s a question that I get asked all the time and will try to answer in this article. Two months ago, I was contacted by Duane, a gentleman I met at the 2015 F-Class Nationals. He was interested in building a rifle with the new Master Class Low Profile F-Open Stock, created by Carl Bernosky and Alex Sitman of Master Class Stocks.
I have known Alex Sitman for many years, and use his stocks exclusively, but was not very familiar with his new Low Profile F-Open stock. After a brief conversation with Alex, I placed an order, and had the stock inletted and bedded at my shop in a month. My first impression was “Wow that’s a long stock” — the forearm is significantly longer than on the original Master Class F-Class prone stock. I bolted the barreled action in, and squeezed the end of the forearm and barrel together, the stock flexed a little bit, but not as much as other designs that I have tested. I think that’s due to having “more meat” in the receiver area. The full stock depth continues farther forward that on some other “low profile” designs. That makes the stock stiffer in the vertical plane, reducing the hinging effect forward of the action. The stock was finished in gloss black per the customer’s request. Interestingly, I found that the multiple layers of paint and clearcoat stiffened the stock up quite a bit.

Low Center of Gravity Tames Torque
Compared to the original Master Class F-Open stock, the barrel sits about an inch lower. Lower center of gravity equals less torque, and that is very important when shooting heavy bullets in fast twist barrels. Another significant improvement is that the toe of the stock is flat and parallel to the forearm. I added a 3/4″ track rail in the rear, and milled the underside of the fore-end to create two parallel “rails” in the front to help the stock track better.
One of the biggest reasons why I like Master Class stocks, is the pistol grip. I don’t shoot “free recoil” and a comfortable pistol grip is super important to me when selecting a stock. The new Master Class Low Profile stock shares the same grip as the old model. This allows the stock to accommodate either a “hard hold” style or a more free-recoil style of shooting — whatever the rifle’s owner prefers. This design versatility is one reason I recommend Master Class stocks. Shooters may experiment with either shooting style to find what suits them best.
Cartridge Choice — A 40° .284 Win Improved
Duane decided to have the barrel chambered for my 284 KMR IMP (Improved) wildcat. What is .284 KMR IMP and why choose it over the straight .284 Winchester? Improved by definition means “made better”, I took a great cartridge, and modified it to increase capacity, reduce pressure, and increase brass life.
There are many “improved” variants of the original .284 Winchester: 7mm Walker, .284 Shehane, .284 Ackley and so on. My version, the 284 KMR IMP, shares the .010″ blown-out sidewalls of the .284 Shehane, but I have further increased the case capacity by changing the shoulder angle from 35 to 40 degrees. The 284 KMR IMP allows you to almost match magnum cartridge velocity in a standard-bolt-face action. If you want to run 180gr-class 7mm bullets over 2900 FPS, it is cheaper and more convenient to have a barrel chambered in 284 KMR IMP than to spend $650 for a magnum bolt.
Tuning Loads for the .284 Win Improved Cartridges
The 284 KMR IMP seems to have two nodes, one around 2820 fps and other at 2940 fps. My match load clocks at 2935 fps with single-digit ES. Note –I selected that load based on accuracy, NOT raw speed. A lot of novice (or hard-headed) shooters make the mistake to push their cartridges to the max, and disregard more accurate loads at lower velocity.
The sport of F-Class is rapidly growing, and the equipment used is improving constantly. I remember that only few years ago, an F-Open rifle that could shoot sub-one-inch of vertical at 300 yards was considered competitive. Now, we are pursuing sub-one-inch vertical at 600 yards! It takes a great rifle to approach that goal, but it is also up to the shooter to learn and experiment as much as possible in order to achieve success.
Dies for an Improved .284 Win Cartridge
One of the biggest challenges in campaigning a wildcat cartridge has been obtaining great dies. When searching for custom dies, it almost seems like that the odds are stacked against us. The most common problem is wait-time — custom die orders can take months to be completed. Also, most custom die makers want you to send them two or three cases, each fire-formed three times. I find that funny because if could somehow properly size the cases for three fire-forming cycles, I would not need a sizing die.
Custom-made dies should size the case just right, but sometimes the die’s internal dimensions are slightly off, and this leads to problem number two: dies sizing too much (or even worse) too little. I had a one “custom” die that would not size the bottom of the case enough. This made the extraction of fired cases very difficult. I feel that the best option (if available) for shooters interested in wildcat chambers is to have their gunsmiths make the dies. I offer that die-making service in addition to barrel chambering.
BAT Machine “M” Action
Duane decided to use a BAT M action for this rifle, and I think that he could not have made a better choice. We are blessed with many good match-quality receivers: Barnard, BAT, Borden, Kelbly, Nesika, and Stiller just to mention a few. These are all very well-made and suitable for F-Class. Among BAT Machine Co.actions, I like BAT models M, MB, and 3LL best. I prefer these because because of their size (large bedding footprint) smoothness, timing, options available, and last but not least visual appearance.
Trigger: I recommend and use Jewell triggers. Other good options are: Kelbly, CG Jackson (good 2-Stage) Anschutz (best 2-Stage for Bat and Kelbly actions), Bix’N Andy, and David Tubb.
Barrel: Duane made another good choice here. He decided to go with a Brux 1:8.5″-twist, 4-groove cut-rifled barrel. If you look at the F-Class and Long Range benchrest equipment lists, you will see that cut-rifled barrels are currently dominating. Many records have been shot with both button-rifled, and cut-rifled barrels. I have shot both, and prefer cut-rifled barrels. I am not saying that button-rifled barrels are not capable of shooting as well as cut-rifled barrels, but on average, in my experience, four out of five cut-rifled barrels (from top makers) will shoot well, vs. three out of five buttoned barrels. YMMV, but this is what I’ve observed.
Scope: Duane’s rifle was fitted with a Nightforce 15-55x52mm Competition scope with DDR-2 reticle. This optic is ultra clear, reasonably lightweight (28 oz.), super reliable, and has 1/8 MOA clicks — what you want for long range F-Class competition. In this 15-55X NF model, I like the DDR-2 reticle best, because fine cross hairs (FCH) are hard to see in heavy mirage. The DDR-2 has a heavier horizontal line, with a center dot. March scopes are also very popular and very well-made.

There are hundreds of cartridge types capable of winning in F-Open. For F-TR you can shoot either the .223 Rem or .308 Win, but you have many load options. This article will focus on proven choices, currently used by the top F-Class shooters in the world. Our discussion will analyze cartridge selection based on the four different F-Class sub-disciplines: Open Mid-Range, Open Long-Range, F-TR Mid-Range, and F-TR Long Range.

Mid-Range F-Open Cartridges
For starters, a .300 WSM is certainly capable of winning mid-range matches but it is not ideal. So what is ideal, and why? F-Class Mid-Range matches usually are usually shot at 300, 500, or 600 yards — or all three. At those distances the 6mm and 6.5mm cartridges rule. In moderate conditions, the 6mm Dasher is unbeatable. Its low recoil along with its super grouping ability and good ballistics make it my number one choice for Mid-Range.
Best bullets for the 6mm Dasher are: Vapor Trail 103gr, Berger 105 Hybrid, 108 BT, and 105 VLD (hunting). Best powders are: Varget, H4895, and Reloder 15.
Choices for Mid-Range in Tougher Conditions:
We all know that conditions are not always “moderate” that’s why something a little bit bigger will save you a “Nine” or two. The 6.5X47 Lapua was designed for 300-meter competition, but as soon as it was released, it was adopted by F-Class, benchrest, and tactical shooters. It offers great ballistics with very low recoil and big “accuracy window”. Lapua makes great brass for it (no surprise there) and Berger makes great bullets: 130gr VLD, 140gr VLD, 140gr Hybrids. Best powders in most barrels are Varget and H4350, I don’t use double-based powders such as Reloder 17 and the Vihtavuori N500 series because of their unpredictable performance day to day (greater temp sensitivity).
The 6.5X47 Lapua necked down to 6mm is also a great option for mid range matches. I was able to easily get 3200 fps with 105 hybrids and H4350.
Choice for Long-Range F-Open Competition
In Long-Range F-Open Class (out to 1000 yards), the big, high-BC bullets rule. If I had to pick one cartridge for F-Class (both mid- and long-range) I would pick the .284 Winchester or one of its variants. The .284 Win is currently dominating in F-Open competition. It offers great barrel life, it is super-easy to tune and its recoil is very manageable. The best bullets for it by far (in my opinion), are the Berger 180 Hybrids. But Sierra’s new 183gr MK bullet (with factory-uniformed meplats) seems to perform very well as does the Berger 180 VLD. Best powders for the .284 Win are H4350 and H4831SC.
Long-Range Only F-Open Cartridge
As much as I like the .284 Win, for long-range competitions I like the .300 WSM even more. If you look at a .300 WSM and a 6mm Dasher side by side, they appear almost identical in geometry — the .300 WSM looks like an “super-sized” Dasher. Both cartridges are currently the “darlings” of long-range benchrest due to their extraordinary grouping ability and huge “node’’ windows. Big accuracy windows allow loads to perform well in different conditions and geographical locations. That’s obviously very important if you travel to compete. The .300 WSM loaded with Berger 215gr or 230gr Hybrids is very tough to beat at long range, and it is currently my number one choice.
The 7mm RSAUM is another outstanding long-range round. It resembles a 6BR on steroids and it is almost as easy to tune. Best bullets for it are Berger 180gr Hybrids, 195gr EOLs, and Sierra’s 183gr MatchKing. Best powders for the 7mm RSAUM are: H4350, H4831SC, and VV N160.
Top Caliber/Bullet Combos for F-TR
In F-TR competition, the choice is clear — a .308 Win throated for Berger 185gr BTLRs and 200gr Hybrids will win in mid-range AND long-range comps. Many championships have been won, and many records set with those two bullets in the .308 Win. To quote Danny Biggs (a two times FTR National Champion) “The 185 BTLR is the best bullet for .308 Win ever made”.
The Berger 215gr Hybrids have been used to win many competitions including recently the 2015 F-Class Nationals. Bryan Litz won both the Mid-Range and Long-Range 2015 Championships using 215s. Bryan’s rifle is shown below:
I recommend chambers throated for the 185/200 grain projectiles over the 215/230 grain bullets. The reason is that if you have your barrel throated out for the 215s or the 230s, you could have a “slow” barrel and max out on pressure before the desired velocity is reached. Optimum freebore for the 230s is too long for the 185/200s, so you would be limited to using only 215/230gr bullets in that barrel.Furthermore, the recoil increase with heavier bullets is substantial, causing the rifle to be more difficult to shoot.
.223 Rem — Not A Competitive Option
I would stay away from the .223 Remington. On paper the 90gr VLD will shoot inside most .308 Win loads even at a 1000 yards. But in reality, on average, the .223 Rem, regardless of what powder/bullet combo is used, cannot compete with the .308 Win.

Conclusion (and Other Options)
This article covers only the (currently) most popular cartridge/bullet combos for F-Class (F-Open and F-TR). As I said in the beginning, many cartridge types are capable of winning but are not listed due to their low popularity, case design, or lack of quality components. All of the above information is based on my personal experience and it is meant to help new shooters choose the right cartridges for F-Class matches. Thanks for reading and good luck — Emil Kovan
