To me this shows a broadhead at work. In fact it is working excellent! However I ran into this on another forum and I was surprised about how many " gun hunters" all the sudden got squeemish about hemmorhage type death. To me this is a spot on example of a perfect bowkill. Kinda of odd that the animal stays in sight and the shooter/cameraman has to witness it firsthand, but correct me if I am wrong...this is what happens most times when you smack an animal in the heart with a broadhead...
