My 300 blackout refuses to feed with remington subsonic 220 grain ammo. it works just fine with the pnw 147 grain fmj but not the remington. it seems to be shortstroking ie. coming back far enough to eject but not strip the next round. also when locking back on an empty mag it seems to catch on the carrier rather than the bolt...
short of doing any major surgery to my gas system, any suggestions? i have no suppressor so should i just stay away from subsonic?
16 inch barrel by the way
