Abstract

A reloadable non-lethal training cartridge is provided comprising a cartridge case, a rear high pressure chamber removably disposed within the base thereof, and a non-lethal payload portion removably disposed adjacent the forward end of the cartridge case. The rear high pressure chamber is provided with a base capable of interacting with a removal tool, such as a hexagonal shaped base capable of interacting with a standard socket. Further, the non-lethal payload portion is comprised of a base and a non-lethal payload, the non-lethal payload and base being removably attached such that one or both of said components may be reused. In addition, the non-lethal payload may be weighted, so as to increase the accuracy thereof.

  1. 1. A reloadable non-lethal training cartridge comprising: i. a cartridge case having: (a) a base comprising an exterior portion, an interior portion, and a base threaded aperture formed within said base from the exterior portion; (b) a circumferential portion adjacent said base defining an exterior portion and an interior, said interior portion defining a low pressure chamber; and (b) a forward end adjacent said circumferential portion, ii. a rear high pressure chamber removably disposed within the base threaded aperture of the cartridge case, said rear high pressure chamber having: (c) a base comprising an outer circumference capable of engagement with a removal tool, an inner portion, and a firing blank insertion aperture formed through said inner portion; (d) a circumferential portion adjacent said base, said circumferential portion comprising an exterior portion having threads formed thereon, and an interior portion defining an interior firing blank containment portion; and (e) a forward end adjacent said circumferential portion, said forward end having a propellant vent hole formed therethrough, said propellant vent hole having an outer circumference, iii. a non-lethal payload portion removably disposed adjacent the forward end of said cartridge case, said non-lethal payload portion having: (f) a base comprising a rear face, a rear edge adjacent the rear face having a frictional engagement means capable of frictional engagement with the forward end of said cartridge case, and a circumferential portion adjacent the rear edge having a non-lethal payload engagement portion; and (g) a non-lethal payload disposed adjacent the non-lethal payload engagement means of said base, wherein the high pressure chamber may be threadably removed from the cartridge case after firing of the reloadable non-lethal training cartridge.
  2. 15. A reloadable cartridge comprising: i. a cartridge case having: (a) a base comprising an exterior portion, an interior portion, and a base threaded aperture formed within said base from the exterior portion; (b) a circumferential portion adjacent said base defining an exterior portion and an interior, said interior portion defining a low pressure chamber; and (b) a forward end adjacent said circumferential portion, ii. a rear high pressure chamber having: (c) a base comprising an outer circumference having a non-circular shape so as to allow engagement with a removal tool, an inner portion, and a firing blank insertion aperture formed through said inner portion; (d) a circumferential portion adjacent said base, said circumferential portion comprising an exterior portion having threads formed thereon, and an interior portion defining an interior blank containment portion; and (e) a forward end adjacent said circumferential portion, said forward end having a propellant vent hole formed therethrough, iii. a payload portion removably disposed adjacent the forward end of said cartridge case, said payload portion having: (f) a base comprising a rear face, a rear edge adjacent the rear face having a frictional engagement means capable of frictional engagement with the forward end of said cartridge case, and a circumferential portion adjacent the rear edge having a payload engagement portion; and (g) a payload disposed adjacent the non-lethal payload engagement means of said base, wherein the high pressure chamber may be threadably removed from the cartridge case after firing of the reloadable non-lethal training cartridge, and the payload portion may be removed and replaced after firing.
