Abstract
Method and apparatus are disclosed for launching electrified projectiles from a firearm (preferably, a shotgun) by using a specially designed breech bolt which also prohibits firing lethal ammunition. The preferred method comprises: opening a receiver of a shotgun by retracting a breech bolt having a central protrusion on a leading end; inserting a cartridge, having an electrified projectile, into a breech of the firearm; wherein the electrified projectile contains a primer and adjacent pyrotechnic propellant; nesting an end portion of the cartridge within the protrusion of the bolt; propelling the electrified projectile from the firearm by striking a firing pin of the shotgun against the primer, thereby igniting the pyrotechnic propellant, of the nested electrified projectile; and prohibiting, by the central protrusion of the bolt, the firing of lethal ammunition from the firearm.
