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: 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 flamethrower.  Bolo Shell: 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: 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. In addition to the above prohibited projectiles, Section 24.1. (a) (3) and (a) (7) (iii) and Section 24.1.(a) (11), unchanged by Public Act 92-0423, list the following as prohibited. Section 24.1. (a) A person commits the offense of unlawful use of weapons when he knowingly: (3) Carries on or about his person or in any vehicle, a tear gas gun projector or bomb or any object containing noxious liquid gas or substance, other than an object containing a non-lethal noxious liquid gas or substance designed solely for personal defense carried by a person 18 years of age or older. (7) (iii) Any bomb, bomb-shell, grenade, bottle or other container containing an explosive substance of over one-quarter ounce for like purposes, such as, but not limited to, black powder bombs and Molotov cocktails or artillery projectiles; Section 24.1.
