[QUOTE="Lefty7mmstw, post: 860671, member: 48043"] Long bullets for a bore that are close to max. for your recommended twist are harder to get shooting well, but not impossible. My 9" twist ar in 5.56 nato consistantly puts five 75 to 77 grain hpbt's into a moa at 100 with peep sights, or slightly more if I'm cross eyed that day. My 7rem is shooting the 171 barnes match in a 9 and change rem barrel to 1" at 200. My 300 rum is eating the 225 hornady hpbt to .6 moa at 200yards. I do shoot more mid weight bullets than heavies though. [/QUOTE]
