Abstract:
A pliant projectile for use with a cartridge including a powder charge which, when ignited, generates expanding gases comprising:a projectile body of a soft elastomeric material, said projectile body having a front end, a rear end and a central void, said central void extending from the rear end into the projectile interior; a piston member, having a face surface and a force transfer element, mounted adjacent the powder charge; and a motion transfer member including a projecting element adapted at one end to be engaged with said force transfer element and, at the other, to be received in said central void interior, said piston member being adapted to be displaced by the expanding propellant gases of the powder charge when ignited; whereby the projectile, when used in a weapon, functions so that upon ignition of the powder charge, under the influence of expanding gases resulting from the powder charge ignition within the weapon, initially deploy said piston, said piston engaging said motion transfer member to bring said transfer member into contact with the interior of said projectile body causing said projectile body to stretch and thereby reduce its diameter to enable easy passage through the weapon, the expanding gases further deploying both said projectile body and said motion transfer member until said piston contacts said projectile body rear end, after which expanding gases further deploy said projectile body and said transfer member until said projectile body clears the weapon.
