It is possible to really split hairs with this kind of conversation.Killing a mature buck with archery equipment is a respectable feat regardless of what phase of the season it happens in.No doubt you will get away with more mistakes when they are preoccupied to the degree they are when chasing or defense of territory but even with that they don't come easy.
I think having an easier time of it once in a while is the way the hunting god's keep us coming back for more!
