  • VARIABLE RANGE AMMUNITION CARTRIDGE FOR ELECTRICAL DISCHARGE WEAPON
    Publication number: 20090025597
    Abstract: An ammunition cartridge for an electrical discharge weapon having at least one dart positioned within a dart chamber in the housing. The cartridge has at least one adjustable barrel for selection between close and extended ranges and a joint and port for adjusting pressure in the barrel. In another form the cartridge has two fixed barrels and a retractable deflection ramp for selection between close and extended ranges.

  • Non-lethal ammunition
    Publication number: 20080017064
    Abstract: A non-lethal ammunition comprising a projectile having a nose component, a driving band adjacent the nose component, and a base component, wherein a densified material is used to control weight distribution of the projectile to improve flight, stability and delivered impact energy of the projectile and the nose component includes features to maximize impact surface area. The projectile is positioned within a shell having a high pressure and low pressure propulsion system which minimizes velocity variance of the projectile.

  • Frangible non-lethal projectile
    Publication number: 20050066849
    Abstract: A non-lethal impact munition or projectile having a nose composed of a frangible, rigid, polymer foam material such that the nose crushes upon impact with a target to disperse energy, thereby reducing the kinetic energy transferred to the target. Most preferably, the munition or projectile is provided with a cavity to retain a payload, such as marker agents, lacrimators, irritants, inflammatory agents, odorants or inert powders, such that the payload is laterally dispersed upon impact to further dissipate energy transferred to the target.
