A less lethal ammunition round includes a highly pliant projectile that may impregnated with fine heavy particles. The projectile has an interior void into which is placed a force transfer member that engages an interior surface at the forward end of the projectile in front of the center of gravity. Upon ignition of a powder charge, a piston in the cartridge chamber engages the transfer member which, in turn, elongates the projectile as the projectile forward end is driven, pulling the remainder of the projectile, reducing its diameter. This allows a release from the cartridge and passage through the barrel of the weapon from which it is being fired. Stabilizing fins at the projectile base deploy as the projectile exits the muzzle. A breaching round is impregnated with a greater weight of heavy particles and its transfer member has an initial large diameter portion and a terminal smaller diameter portion. The breaching projectile similarly has a large diameter initial void and a smaller diameter terminal void. As the transfer member is urged forward, the forward part of the projectile is extended until the transfer member shoulder engages a similar shoulder in the void and no further elongation of the projectile occurs. The elongation is sufficient to release the projectile from the cartridge and permit it to travel through the weapon barrel without obstruction and without damage to the projectile. |
