Non-lethal telescopically expanding training cartridge for self loading guns

摘要

A cartridge for use in a gun comprises a case, a gas generator, a piston, a stopper, and at least one channel for the passage of gas in and/or around the stopper wherein the piston is axially slideably contained in the case, the gas generator is located within the case adjacent a first end of the case, and the stopper is slideably contained within the piston for closing the at least one channel.

1. A cartridge for use in a gun, the cartridge comprising a case, a gas generator, a piston, a stopper, and one or more channels for the passage of gas in or around the stopper, wherein the gas generator is located within the case adjacent a first end of the case, and the piston is axially slideably contained in the case, the piston having a first end proximal to the gas generator and a second end distal from the gas generator, and the stopper is slideably contained within the piston for closing the at least one channel,
wherein the gas is generated or expelled by the gas generator upon contact with a firing pin of a host gun and initially the gas from the generator can flow through the one or more channels in or around the stopper and exert pressure on a bullet, wherein as the gas pressure rises, the flow of gas past or through the stopper causes the stopper to move thereby shutting the one or more channels and preventing gas flow to the bullet and then to atmosphere.
