Firearm cartridge with pre-pressurizing charge
First Claim
Patent Images
1. A firearm cartridge comprising:
- a casing;
a projectile connected to the casing;
a pre-pressurizing charge located inside the casing behind a rear end of the projectile;
a main propellant charge located inside the casing behind the rear end of the projectile; and
a barrier located between the pre-pressurizing charge and the main propellant charge, the barrier being adapted to substantially prevent the pre-pressurizing charge from igniting the main propellant charge, but allow pressure from burning of the pre-pressurizing charge to the exerted on the main propellant charge wherein the pre-pressurizing charge is located adjacent the rear end of the projectile.

3. A firearm cartridge comprising:
-
a casing; projectile connected to the casing; a pre-pressurizing charge located inside the casing and located adjacent a rear end of the projectile; and a main propellant charge located inside the case, wherein the pre-pressurizing charge and main propellant charge comprise suitable materials such that the pre-pressurizing charge can burn and exert pressure on the main propellant charge without igniting the main propellant charge and, the connection of the projectile to the casing prevents the projectile from being disconnected from the casing until the main propellant charge is ignited.
