Patent ID: 7210410

Claim:
For use with a firearm, an ammunition round having a powder charge which, when ignited, generates expanding gases comprising: a) two or more projectile bodies of a soft elastomeric material, each of said projectile bodies having disk shape and a central void; wherein each of said projectile bodies is comprised of a plurality of segments joined adjacent to said central void by a relatively thin web element; b) a piston member, having a face surface and a force transfer element, mounted adjacent the powder charge, said piston member being adapted to be displaced by the expanding propellant gases of the ignited powder charge; and c) two or more motion transfer members each having a projectile body support surface and, on one side of said surface, an area adapted to be engaged with said piston force transfer element and, on the other side, a projecting element adapted to be received in said central void, said projecting element being adapted to engage an overlying motion transfer member; whereby ignition of the powder charge creates expanding gases initially deploy said piston, said piston force transfer element engages the overlying motion transfer member to bring said transfer member through said interior of said projectile body into contact with an overlying motion transfer member causing each said motion transfer member to engage an overlying transfer member until said piston, under the influence of the expanding gases deploys all of said projectile bodies out of the weapon.
