In some circumstances, when shooting a trophy grade non-dangerous game animal, any shot is better than no shot, even if the shot is unlikely to kill, only wound and slow the animal so that the hunter can make a follow up killing shot. I'll leave the question of ethics for others to answer, but few hunters are going to pass on a great trophy, even if the shot opportunity presented is marginal.
Just for clarification a gut shot or lower leg is an acceptable shot for a trophy animal? How about a non trophy, non dangerous game animal? Should I wait for a good solid kill zone shot or do the same rules apply?
I anxiously await your answer.
