I've seen some really accurate AR's that shot excellent groups but not with m855 ammo.I believe the acceptance of M-855 is nearly 4 inches for a 10 shot group.
If your cases are G.I. 7.62 brass they were probably fired in machine guns ,which are known to have somewhat large chambers and violent ejection. You could possibly correct this by using a small base sizing die for reloading this type of brass.
The worst I ever fired was a savage 99 Featherweight, in .358 Winchester, with a steel Buttplate. The recoil surprised me,I did'nt think it would be that bad.Was shooting 200 grain bullets.
Midway used to pack a piece of paper with their new brass recommending that all new brass be resized due to possible dents and damage to the neck of the cases due to tumbling and also shipping of the brass.
