It is legal to hunt at 12 years old in some states.
Edit: I bought enough trigger locks for all my long guns and pistols for under $100. There is no excuse not to have them installed and I live alone. My guns are also in a locker as well as trigger locked. My ammo is in a different room in a safe box screwed to the closet floor from inside the locked box. All this was well under $200 including the gun locker.
