I shot a big cow elk this year with the Muzzy Trocar crossbow head ,2 fixed & 2 mechanical. Hit her facing me in the front of the chest arrow exited out the right ham next to the butt hole...that is over 3 1/2 feet of penetration.She went 75 yards on a run and folded up dead. When I opened her up her insides were devestated. Just shredded from throat thru lungs thru guts and a 3" hole in the rump. Good enough for me!
