There are quite a few states (and I believe IN is one of them if I recall) that a fellon may not own a bow or Muzzleloader in either.

The definition of a 'firearm' or 'weapon' per state law varies quite naturally from state to state. Frequently there are clauses which directly prohibit felons from owning any time of 'projectile' weapon at all. Doesn't mean he can't go buy one, because who would know but him.... but he best not be caught with it.
