where is your point of aim for this to happen?only way you are shooting off a jaw without killing the deer with the point of aim at the base of the skull where the neck meets is missing by more than 6", which is likely a wounding shoot no matter where on the animal your point of aim is considering the size of the average whitetail
If you think that "missing by more than 6" " is impossible for you, you haven't shot many game animals in real life. And, you should go back and measure some deer.
You will find that even a 6 inch "miss" will most often be quite lethal if the point of aim is half way up and centered on the chest cavity of the animal. An animal can toss or turn its head for any number of reasons in fractions of a second, but its chest is far less likely to suddenly move.
Head and neck shots work dramatically IF they hit the spine or the brain which allows for less than 2 inches of "miss" before you have a deer that can still run like a deer, but which will not die until it starves or dies of thirst. My advice is to NEVER take a head shot as the first one.
