Shot a doe tonight, with the rage, dropped her like a stone, shot placement wasnt the best cause I shot in a window between trees, and I thought she was stopping, but took two steps. Ide really like to get a better rib cage shot on one, and see the dammage. The cut this thing made on that doe was impressive tho... I was pretty skeptical about these heads, but they work. O ring system is my only gripe..
