For the purposes of this Section:
"Armor piercing bullet" means any handgun bullet or handgun ammunition with projectiles or projectile cores constructed entirely (excluding the presence of traces of other substances) from tungsten alloys, steel, iron, brass, bronze, beryllium copper or depleted uranium, or fully jacketed bullets larger than 22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25% of the total weight of the projectile, and excluding those handgun projectiles whose cores are composed of soft materials such as lead or lead alloys, zinc or zinc alloys, frangible projectiles designed primarily for sporting purposes, and any other projectiles or projectile cores that the U. S. Secretary of the Treasury finds to be primarily intended to be used for sporting purposes or industrial purposes or that otherwise does not constitute "armor piercing ammunition" as that term is defined by federal law.
The definition contained herein shall not be construed to include shotgun shells.
"Dragon's breath shotgun shell" means any shotgun shell that contains exothermic pyrophoric mesh metal as the projectile and is designed for the purpose of throwing or spewing a flame or fireball to simulate a flame-thrower.
"Bolo shell" means any shell that can be fired in a firearm and expels as projectiles 2 or more metal balls connected by solid metal wire.
"Flechette shell" means any shell that can be fired in a firearm and expels 2 or more pieces of fin-stabilized solid metal wire or 2 or more solid dart-type projectiles.
This exemption does not authorize the general private possession of any armor piercing bullet, dragon's breath shotgun shell, bolo shell, or flechette shell, but only such possession and activities which are within the lawful scope of a licensed business described in this paragraph.
