All, Im a new member, but have been reading this forum for some time. Lots of great advice, but cannot find any info specific to my concern with a new rifle build, and caliber selection. Im looking into a 7mmRSAUM, for a long range hunting/long range tac competition rifle that I could also shoot in F-Class. I know that it will be a compromise rifle, and far from a true open class F-Class rifle. So...question is, with a 26" barrel, will I get the velocity needed to make the 7mmRSAUM worth while, or is there a better caliber for that velocity range/barrel length? Id like to shoot BVLD 180's, build on a mag action to load them long, and it will be a repeater action. Will run it compensated for all but F-Class, and take it off and put a thread adapter on. Barrel life is a concern, but not a deal breaker, Im assuming that whatever Im shooting will be hot, and hell on barrels anyway. Im trying to get a moderate recoiling rifle, with magnumish performance, so Im not interested in 300 Win Mags etc (I have one now). Really looking forward to any advice you all have, thanks!
