Abstract: A self-propelling projectile comprising a projectile body at the normally forward end of said projectile, a propellent charge at the normally rearward end of said projectile, and a primer element located between the ends of said projectile for ignition by side firing or percussion; there being means for maintaining said components in integrated relationship and with communication between said primer element and said propellent charge whereby upon explosion of said propellent charge the force of the latter will be directed against the base of the projectile body.

Abstract: A base wad for shotshells integrally constructed of non-linear polyethylene and a mineral from the class consisting of asbestos, barium carbonate, chalk, and talc in approximately equal portions by weight; said base wad being dimensionally stable, having requisite flowability for snug locking with the shotshell head and the rim thereof; and being of appropriate elasticity to provide excellent sealing of the gases of explosion while being readily restored to normal condition for ease of ejection of the shotshell from the gun firing chamber.
