RE: Why would you want a pass through??
KoBear, military rounds are meant more for maiming than for killing, the idea is to create havoc in the person being shot body, if you wound somebody it takes the wounded of the battle field and the 2 men to carry them.
I prefer to use corloks myself the bullet expands massively staying in one piece causing massive internal shock, little hole in, big hole out, tons of blood for trailing. Hunting bullets are designed to kill, not maim.
