Shooting my AAC-SD in 300BLK is a hoot. I'm still working up some loads after liberating some factory loaded Hornady 208s from their brass.
So far, factory ammo has made it a 1 minute gun to 200 yards. Hitting a 10" steel at 300 is about 75%. At 400, the thing goes crazy. I can't get within a foot of a man-sized target.
I do have some 240 SMKs to load up, and I'm hoping they do well (my wallet isn't). Does anyone have any experience with an a subsonic load that is accurate past 300 yards?
