I believe most states follow the fatal shot rule. There's a good reason for it. If you are hunting and you see a wounded animal, and the deer belongs to the person who drew first blood, and you don't see or hear anyone coming, what do you do? 1) not shoot the deer, and leave a wounded animal to suffer and probably die later in the woods; 2) shoot the deer and leave it lay, not knowing whether anyone will ever track it down and claim it; or 3) shoot it and take it home and eat it. The only rule that allows for the last option is the fatal shot rule, and the last option is the one that best insures the deer does not continue to suffer and/or go to waste.
