Under FEDERAL law, which applies in every state, you must be 21 to purchase ammo for a handgun. Ammo that may be used in a handgun or rifle may be purchased at 18 IF the seller knows that it will be used for a rifle.
Yes.
Generally speaking, you have to be 18 to buy rifle or shotgun ammo, and 21 to buy handgun ammo.
It depends on what you mean. 1. If you mean semi-automatic (sometimes referred to as automatic), it means a handgun that auto-loads the next cartridge in order to fire it, but fires only one cartridge for each pull of the trigger. 2. If you mean a full auto, it means a handgun that will continue to fire as long as you hold the trigger, or until it runs out of ammo.
By federal law you may own or possess a handgun at age 18, but you cannot purchase handgun ammo or a handgun from a dealer until age 21.
