  • Patent number: 5225628
    Abstract: A high impact low penetration round includes a transparent casing and a plurality of deformable pellets fired from the casing as projectiles. The pellets are formed of a lead wax material that flattens and deforms upon contact with a solid object. Contact with a solid object discharges all of the kinetic energy associated with firing the pellet and transfers this energy to the object so that the pellet will not ricochet or penetrate the object. The pellets are shaped to tumble in the air to enhance energy loss and to aid in the detachment and distribution of the pellets. The rounds can be used as shotgun ammunition at close range to provide an effective anti personnel round with a lethality that diminishes rapidly after an effective range of about thirty-five yards.
