Best F-Class Calibre for open competition

338 LM is Ok for shooting steel but it’s not small group shooter and F CLASS is all about Shooting small groups . RJ

I'm an F T/R guy, but if I were to ever go open, then I'd go with a 284 chamber. 80% to 90% I of the guys I know at Nokomis in Open seem to use since its tried, tested, and true.

l believe 338 LM is not allowed under the f class rules (8 mm maximum).
Even if it was its way to expensive to shoot
and due to no muzzle break being allowed in f class world this makes it uncomfortable for shooting all day.

Don't get me wrong it a great caliber for long range shooting but not for F Class discipline.

Every statement in this post is indeed true. Caliber is limited to 8mm for competition.

Your club/range of choice might allow you to shoot a 338 LM (sans muzzle brake) at a match... but you will effectively be "competing with yourself" and your score will not count towards the match results and National Standing.

284win is the easy button for long range F Open, mid range people may use 6 Dasher like caliber.

Barrels are an expendable item in this game, but there are a whole family of cartridges with a .473 bolt face and 2.8 inches length so it's possible to start in 6.5 CM and once your apprenticeship barrel loses accuracy order a .284 Win barrel, or get the TR bug and go .308 or maybe peruse the rest of that family's options.
