Yea..it happens. My neighbor's son shot a youngdoe last year with a .50 CVA in-line and a Powerbelt hollowpoint bullet at about 30 yds. He hit her at an angle quartering towards him in the right shuolder and the bullet exploded inside her there was not one small fragment that exited..what a mess! An older gent I used to work with kept a flattened .50 round ball in his toolbox as a conversation piece. It was a little smaller than a quarter, and hehad taken it from a nice buck he shot with a CVA Mountain rifle some years back. It smashed through a shoulder, passed through a rib on the opposite side, and stopped at the hide but not before it had slid under the hide all the way back on top of the deer's hind quarter. Personally, I have never had that happen with any of the deer I've shot with a muzzleloader...BPS
