Abstract
The present invention discloses a reduced energy training cartridge for use in a straight blowback operated firearm having a barrel with firing chamber, the cartridge comprising a cartridge case being defined by a rear portion with an external groove, a front portion having a velocity reduction structure and a wall with an outer surface and an inner surface, a sabot slideably engaged within the cartridge case, the sabot having a rear portion with an outside diameter substantially equal to the inside diameter of the inner surface of the cartridge case and which contains a gas sealing and braking structure and a primer disposed in the rear portion of the cartridge case where, upon percussion of the primer, the cartridge case rapidly slides relative to the sabot until such point when the velocity reduction structure of the cartridge case engages with the sealing and braking structure of the sabot, thereby stopping further movement of the cartridge case relative to the sabot, The present invention also contemplates using a metallic case in combination with a non-metallic or polymer sabot.
