me and my buddy went shooting at the range and we were shooting my AR-9mm a round pre detonated before chambering so it was like a mini grenade went off, luck me i was standing beside him looking through the spotting scope and i got hit with a piece of brass from the case about a 1/4 inch square that went about a inch into my shoulder, i had to dig it out with some tweezers to make a long story short, be
careful of what your doing! even though this was a factory round things can happen
