Abstract: A system is disclosed for defeating enemy missiles and rockets, particularly rocket propelled grenades (RPG's). The first step is to identify the firing of a missile by the use of sensors that give the approximate distance and bearing of the incoming missile. A non-lethal cloud of pellets is then launched from the target, which can be a building or vehicle or the like, in the general direction of the missile. The pellets are housed in a series of warhead containers mounted at locations on the target in various orientations. The warheads are triggered to fire a low velocity cloud of pellets toward the incoming missile. The pellets then collide with the missile a certain distance away from the target causing premature detonation of the missile, and/or possible severe damage to the missile, and/or deflection of the missile, due to the relatively high velocity of the missile.

When an impact section of a firing pin of the percussion device is struck, the striking force pushes the firing pin to move forward such that the total length from a plug head formed in a front end of the plug to the impact section is shortened.

Besides, the compressed gas immediately rushes into each paintball feeder in the cartridge so as to shoot each paintball in a respective one of the paintball feeders out of the cartridge.

Abstract: A method for the dispersion of projectiles from guns capable of firing multiple projectiles in rapid succession whereby some of the projectiles are modified by moving the center of mass of the projectile away from it's central axis and oriented prior to firing. This, in combination with bring fired from a rifled gun barrel, imparts velocity to the projectile upon exiting the gun barrel at right angles to the barrel. This velocity along with the higher muzzle velocity will cause the modified projectile to diverge away from the trajectory of a standard projectile. The magnitude of the divergence will vary with the distance the projectile's center of mass is away from its central axis, and the placement of the modified projectile strikes around the bull's-eye will be determined by the loading orientation of the modified projectile. Firing a multiplicity of standard and modified projectiles in rapid succession will produce an accurate dispersion pattern on a target, increasing the hit probability on that target.

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.

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.

Abstract: A shot charge and wad structure includes a thick-walled plastic shot wad cup having integrally connected base and continuous sidewall portions which together define a shot pocket with an open end for receiving and supporting a charge of shot. The structure also includes a shot pellet charge in the shot pocket composed of tungsten and having a hardness generally at least equal to that of the gun barrel in which a shotshell containing the pellets is to be fired. An insert disk is disposed in the pocket below and in supporting relation to the charge of shot pellets in the pocket. The disk is composed of a material, such as aluminum, having a hardness sufficient to prevent any of the pellets in the charge thereof from embedding therein or in the base portion. Instead, the charge cleanly separates from the pocket of the cup upon firing of a shotshell containing the charge. The shot pocket can be either generally square or circular in cross-section.

Abstract: A multiple projectile cartridge for a handgun comprises four spherical projectiles embedded within a paraffin/powder filler material contained within a plastic casing enclosed in a conventional small caliber shell containing the usual primer assembly and powder charge. The projectiles each have a diameter slightly less than the internal casing diameter which maximizes the number of shots and mass traveling at high velocity to strike the target. The single row of projectiles are longitudinally spaced from each other by the filler material so that the projectiles do not crunch together during flight, resulting in a shot string held together in a close pattern of high ballistic integrity. The diametral relationship (i.e., clearance) between the projectile diameter and internal casing diameter also prevents the plastic casing side wall from laterally expanding as the casing travels through the gun barrel to prevent groove fouling.
