It seems to me when a shot is fired, the head and neck are the first to react. With such a small margin for error, I think it would be silly to try it intentionally with a bow. As far as the neck shot with a gun, I have never lost a deer when it was hit in the neck, never had to even track one. I have, however,lost deer or had to track deer shot in the vitals.Have to say I like a neck shot with a rifle.
