Why is bow season longer than rifle season?

The use of rifles in hunting is far more efficient than using a bow; it it much easier to strike and fatally wound a deer with a rifle than with a bow. As such over a set period of time more animals could be killed with a rifle than with a bow. If rifle season was as long as bow season many more deer would be bagged, which would put a strain on the deer population. Thus, bow season is longer than rifle season because rifle hunting does much more "damage" than does bow season.
