Adrenaline is very potent in animals don' t ever forget that. Onto head neck shots it is a matter of 1/4 inches when you head neck shoot animals. I am not agreeing with the majority here i have killed alot of animals with one shot kills with a rifle head neck area i have also passed on alot of animals that i could not gaurantee a sure kill on, it boils down to a person must know with certaintee where his bullet or arrow is going to hit not just a general area. The reason people get so upset over head neck shots is there is little room for error maybe the bullet was a little high or a little low but it certainle did not detsroy the brain wich was probably the intent if it had the animal would have been down. Everybody wants to jump on the wagon here and condemn your partner but i am sure some people have had three shot kills in the body cavity also. speaking of adrenaline this should really get some people riled up.
