I'd hate to tell ya, but just because you shoot at animals with a rifle or a shotgun, doesn't mean you harvest an animal everytime you shoot (if that were true every deer/duck/squrriel, etc would be extinct). Guns were fashioned by people,like bows, for the same reasons bows were made. Just because a bow doesn't go "bang", and use bullets- it is still as dangerous and capeable of killing animals.
