Tim,
I can honestly say that I' ve never taken a head shot, it' s one of the most moveable parts of the body. I try to wait it out for a shot behind the shoulder or one in the chest. If the animal walks away, I get to go after him another day & I have the great experience of getting to see the animal in the wild. I' m not going to judge someone for the shot that they took b/c I wasn' t in their shoes to make the decision. People alot of times can say I would' ve done it or I wouldn' t have done it.........you just don' t know until you are in that situation.
