I assume I have hit him well as I normally watch the reaction and them until they fall. Stand or blind hunting allows an easier shot most of the time if you are patient.
Last year I had my wife shoot her buck twice because I wasn't sure how high or how far back the bullet was . He went about 100 yards, stopped, then started walking toward the fence and brush.
She hit him again to make my life easier. Weak little .270.
