A friend I hunt with shot at a doe. He was using a Traditions .50 caliber Kentucky percussion cap rifle. And without doubt, he is a great shot with that rifle. He was so sure of the shot that he tried a head shot. He explained... he did not want to waste meat. Needless to say the deer dropped where it stood when shot. And he was sure it was a behind the ear type shot. But as he reloaded, he could not believe his eyes when that thing got up and began to stagger off... he tells, I panicked. And I never would have believed that deer was alive. The next shot was a Wisconsin backside heart shot as we call them. Right up the hind end. To this day, he's never tired another head shot on a deer that I know of. He had blown that lower jaw clean off.
