Cartridge Choices for F-Class Competition

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 Remington Cartridge Diagram.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. [Editor: The equipment lists at major F-TR matches will confirm Kovan’s conclusion here.]

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

Williamsport World Open 1000-Yard Championship

Williamsport World Open original Pennsylvania 1000 yard benchrest club

Held July 14-15 at the Original Pennsylvania 1000-Yard Benchrest Club, the 2018 Williamsport World Open attracted a large field, with over 130 competitors. During the two-day event, shooters competed in a four-match Aggregate comprised of one Light Gun Match and one Heavy Gun Match on Saturday followed by LG and HG matches on Sunday. The conditions this year were switchy at best, with light rain Sunday morning preceding the start, and typical Williamsport winds. CLICK HERE for complete results.

Check out this superb 100-8X group. Could your rifle do that at 1000 yards?

Kieffer Dominates Match, Winning Both Classes and Overall
David Kieffer dominated the 2018 World Open. This talented shooter earned multiple titles: Two-Gun Grand Champion, Light Gun Grand Champion, and Heavy Gun Grand Champion. David had a steller performance with a 5.433 Two-Gun Group Size Aggregate. Shooting a 6.5×47 Lapua rig smithed by Mark King, Kieffer won the Two-Gun Overall with 10 Rank points (lower is better). Second in Two-Gun was Charlie Lentz with 47 Rank Points. Third was Charles Loebsack with 52 points. There was a turn-out this year of 130 entries in Light Gun Class (17-lb limit, 10 shots per target) class and 130 shooters in Heavy Gun Class (Unlimited weight, 10 shots per target).

Winning Equipment: Dave Kieffer’s winning rifle was a Mark King built 6.5×47 Lapua using H4350 and 140 grain Berger bullets. This featured a BAT action, Krieger barrel, and Nightforce action.

At Willliamsport, the range drops away beyond the firing line, and then rises up again for the target line and pits. There is even a pond down range. This makes for a very scenic view, but also challenging conditions. The Williamsport range is known for tricky winds, with switches and let-ups. There are several flags between the firing line and the 1000-yard targets. It is common to see them pointing in different directions, adding to the challenge.

New Benches at Williamsport 1000-Yard Range
The firing line for the 1000-yard range went through a complete renovation before the 2018 season. Added were 15 new masonry benches with block bases and concrete/plywood tops. The structure over the benches is completely new as is the concrete pad underneath the benches.
