Abstract: The invention relates to a disintegrating bullet that breaks apart at set distances in order to better engage targets such as unmanned aerial systems.

Abstract: A closure wad is placed at the mouth of the launching end of a shotgun cartridge before the mouth is crimped down to seal the launching end of the cartridge. Both the walls of the closure cap and the walls at the mouth of the plastic envelope are crimped down together, thereby forming a substantially impermeable seal at the launching end of the cartridge. In addition, the inventive closure cap substantially reduces the detritus which is sometimes expelled when a launcher cartridge is fired.

Abstract: A projectile is provided, in accordance with the present invention that includes a gas seal, an absorption zone, a core material containment area, a mass of material within the containment area and an actuator member. The containment area is characterized by the ability to peel back upon itself on impact, thereby releasing the mass of core particles after impact. The actuator, is releasably fixed to the hull open end, and has a stem member that projecting into the mass of material. Prior to initial impact the actuator maintains the core material within the containment area hull and, up initial impact, the actuator is continues to be propelled forward, along with the core material.

Abstract: A projectile is provided, in accordance with the present invention that includes a gas seal, a wad absorption zone, a core hull, a mass of projectile core particles within the hull and an actuator member. The hull is a cylindrical member having an open end and made from a material, such as soft plastic, that is characterized by the ability to peel back upon itself on impact, thereby releasing the mass of core particles after impact. The actuator, is releasably fixed to the hull open end, has an exterior side and an interior side and one or more stem members projecting into the mass of core particles. Upon impact, the actuator is released from the hull open end and continues to be propelled forward, along with the core particles. When the projectile impacts a target, the hull peels backward upon itself thereby releasing the actuator and the mass of projectile core particles.

Abstract: A moisture seal over shot wad for a roll crimped shotshell casing. The seal has a pair of spaced tubular flanges which comprise the rim portion of the disk shaped over shot wad. The tubular flanges are designed to receive the terminal end of the shotshell casing as the roll crimp is formed to frictionally engage the terminal end and seal the casing against the intrusion of moisture.

Abstract: A power load for use with an underwater spear gun including a casing, explosive material within the casing, the casing having one closed end adapted to open when the explosive material explodes. The closed end is sealed with a sealing compound to prevent water from penetrating the casing. The closed end may be crimped closed or closed by means of a wad or plug of suitable material. The sealing compound may be a silicone rubber or polylvinylchloride which permeates the closed end.
