Just finished load development for my beretta brx1, 20" very happy with the results. The rifle has a light, but creepy trigger so match accuracy will be tough, but it is accurate. Progress was slowed by a broken decapping unit on my die, but all fixed now, even bought my lgs outta his 85 sgk's.
85gr is where I settled for my 243 AR-10 too, big enough for deer but not overkill for coyotes either. Pushing it with H4350 though, just over 3200fps.
Nosler partition has killed everything it’s been pointed at out to 450 yards. As a loaner rifle it’s easy to shoot and with a good bit of bragging about what a great track records it’s racked up, even inexperienced shooters have always had a lot of confidence in it.
Currently running 80 gr TTSX over IMR 4895 from a 18" Ruger American compact at just over 3000 fps. Probably can improve but it shoots tight groups and it's a sub-400 yard gun anyways. Great for kids.
