I took my rifle out shooting today and tried some 7.62 ammo by American Tactical which is made in turkey.The rifle is a DPMS LR-308 The problem was it would not have enough pressure to operate the bolt so the rounds I had to rack back every shot. Anyone had this problem? I have shot Nato through my gun before with no problems but was wondering if anyone had some tips. Thanks ahead of time! Besides the problem the ammo was sub moa accurate.
