I went to the range last Friday and was talking to one of the range control guys, old hillbilly guy but absolutely hilarious. I spent half the time just trying to understand him so I didn't get everything he said but he was talking about a 'new or newer' kind of round that when fired at a person it will enter and sprawl. But if it hits, say something like a 2X4 in a wall, it will not go through it, it stops. So you don't shoot your neighbor/family while they are sleeping. Has anyone heard of anything like that?? It got me a little curious and I decided to check it out. A while back I heard of FAMs using something similar to these "special rounds" but I found out that wasn't the case. It just peaked my curiosity.
