Shot 50 rounds of PMC .45 acp 230 gr fmj today. When I finished the last mag of 8 and went down to pick up the brass I found a whole bullet. When I say bullet I mean just the pill itself right, has rifling marks on it but no signs of making impact with anything, I mean other than the rifling marks it looks like a new pill. I was firing too far away from target to see where each shot went as I was shooting so I walked to target and looked, could only find seven shots. What the crap happened, I mean this pill was right with the spent brass like it was ejected with the brass, I'm stumped. Any ideas?
