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 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

Hulle maak net n grappie oor die 215gr Hybrid, moenie hulle koop nie skiet eder die 200 of 230gr hybrid. Laat weet my maar net as julle die 215s erens sien

Praat maar as hulle jou pla, ek help graag

Capt.

Ek het n 284 Shehane maar as ek alles met hom moet skiet gaan my loop nie hou nie. Ek wil nog een bou om af te wissel mee.

Op langerafstande kook die 300 maar ek wil nie soveel kalibers mee skiet nie. Sukkel genoeg met een.

Ek het n 6.5x47 onlangs gekry. Fireform nog doppe. Met die 123 gr Noslers skiet hy op 500 m n waterlyn soos min. Het n paar pakke Norma Golden Targets. Ek dink hy gaan kook op korter afstande.

[Capt. Yoda]

Frikkie eks self nou so half tussen kalibers/planne, ek was van plan om n 260 te koop en dalk te laat AI maar nou het ek weer n plan om my 300wm n 7mm loop op te sit 7saum of so) en dan n 300wm met n bq langer loop te koop vir 230gr Hybrids maar dan wil ek nog altyd n WSM gehad het maar dan gaan ek weer die 230s lekker vinnig genoek kan skiet?? Te veel planne!

[Frikkie Coetzee]

Te veel kalibers werk nie. Te veel windskuif om te leer.

Maar ek wil n 6xc ook he.......

[Supacow]

hoe weeg die 7-300wsm teen die 284 win op?

[JPS]

Kapt. Daai 260 AI gaan baie makliker wees om deur die shlep te gaan om die geweer te lisensieer en dan weer oor te lisensieer na jy eers moet wag vir toesteming om dit te doen mag dalk net nie die sous werd wees nie.

Frikkie ek sien ons kyk selfde plan met 2 gewere, gaan my 260 nog rig met ng 30" loop vir kort afstand skiet.....

[willem]

skiet self n 6xc met 30' loop en 107 gr sierras , baie lekker kombinasie,daar is geen recoil omvan te praat nie

My 300WSM skiet kookwater. Gebryk hom vir kort en lang afstand.

Daai vinnige geweerkties doen wel goed op 300m ma 500, 600m as die wind pla is my 300WSM baas...

[swc-tr]

Daai vinnige geweerkties doen wel goed op 300m ma 500, 600m as die wind pla is my 300WSM baas...

Maw jy het nog nie leer wind lees nie......................

Nee Sckalk....

Ons leer nog elke dag... wat julle vergeet het moet ons nog leer!

Daar is paar 308 manne by ons ope manne baie kan leer!

Jan dit is so ek wil al baie lank n 260Rem he maar daar is net vir my iets aan n roer wat n groot koel skiet, die 7mm projek is nie iets wat ek hastig voor is nie en ek kan maar vir n ruk lank 2 x 300WMs he dan laai ek maar 230s en 125gr BTs om al 2 te "regverdig". Sal maar sien ek het die week al 3 of 4 keer van planne verander maar wil darem he die papierwerk moet voor November in gaan vir watter kaliber ook. Die WSM se dop spook ook al lank by my wil net seker maak die model wat ek soek kan dam n lang koel mooi vat
