Yes, it didn't say anything in the original post about having a issue with new ammo. Are you letting the charging handle chamber the cartridge or are you assisting it by riding the charging handle by hand? You don't pull the charging handle all the way back and then slide it forward with your hand. Correct way is to pull it all the way back and then release it. Last yr when I was new at all this, I would ride the charging handle, thereby slowing it down , and taking away the force needed to chamber a rnd all the way, I would have to push it the last 1/8 of an inch.(SU16 by the way). Some one on here straightened me out on that.
