Minimum Age to Purchase/Possess Ammunition

Iowa prohibits any person from selling or otherwise transferring handgun ammunition to a person under age 21.1 However, a parent or guardian or spouse who is age 21 or older may allow a minor of any age to possess handgun ammunition for any lawful purpose while under the “direct supervision” of the parent, guardian or spouse, or while the person receives instruction in the proper use of a handgun from an instructor age 21 or older, with the consent of the parent, guardian or spouse.2

Iowa also generally prohibits any person from selling rifle or shotgun ammunition to a person under age 18.3 A parent or guardian over age 18, or another with the express consent of the minor’s parent or guardian, may allow a minor to possess rifle or shotgun ammunition.4 See the Iowa Minimum Age to Purchase/Possess section  for further information.

Regulation of Unreasonably Dangerous Ammunition

Iowa generally prohibits any person from knowingly possessing any bullet or projectile containing any chemical compound or mixture designed to explode or detonate upon impact.5

Iowa generally prohibits the possession of any shotgun shell or cartridge containing “exothermic pyrophoric misch” metal as a projectile, which is designed to throw or project a flame or fireball to simulate a flamethrower.6

The federal prohibition on certain kinds of armor-piercing ammunition  also applies.
