These typically cover; recreational hunting (in states it’s permitted on public land), vermin control (shooting on farming properties), target shooting sports, professional reasons (security and cash-in-transit, pest control and professional hunters). Firearms are classified according to action type by and large.
This means air rifles, break action shoties and rimfire bolt/break actions and Black powder are easiest and most accessible (Cat A), bolt action Centre Fire and pump rifles are next easiest (Cat B).
