ABSTRACT:
A plastic cartridge has a base with a primer pocket and a primer mounted therein. A propellant charge is located within the cartridge and a plastic, collapsible wad is positioned within the cartridge above the propellant charge. A strawlike fusing channel extends through the wad into the propellant charge and is packed with an igniter charge. The fusing channel communicates between the propellant charge and a tracer charge packed within a cavity in a lead shotgun slug. The wad has a plurality of upwardly extending petals which surround the slug within the cartridge and which engage with the rifling of a shotgun barrel when the round is fired.
