Abstract An ammunition cartridge comprising a projectile which is fully telescoped within a flat casing which may be manufactured of identical metal or plastic, glass-reinforced nylon, etc., sections which may be suitably bonded together. The projectile is mountable within a projectile guide tube which is in axial alignment with a booster charge cavity and a percussion primer. The main projectile charge is located within cavities on either side of the projectile tube, which cavities are in communication with the projectile tube via ''''windows'''' which are sealed by the surface of the projectile when the latter is in place. The outer walls of the main projectile charge cavities may be provided with apparatus which allows main charge combustion gases to exhaust from the casing and pressurize the entire firing chamber in order to reduce chamber stressing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A cartridge casing comprising a projectile guide tube therein having means for seating a projectile in a fully telescoped relationship with said casing, booster charge receiving means in axial alignment with said projectile guide tube, primer receiving means in axial alignment with said booster charge receiving means, means, laterally offset from the axis of said projectile guide tube, for receiving a main propellant charge, and window means, normally completely obturated by a projectile fully seated in said guide tube and located at a position removed from each end of said propellant charge receiving means, providing communication between said guide tube and said main propellant charge receiving means so that combustion of a propellant charge in said propellant charge receiving means commences in two different directions only after projectile movement has occured sufficiently to uncover said window means.
Claim 2
Dependent Claim
137 words
A cartridge casing comprising a projectile guide tube therein having means for seating a projectile in a fully telescoped relationship with said casing, booster charge receiving means in axial alignment with said projectile guide tube, primer receiving means in axial alignment with said booster charge receiving means, means, laterally offset from the axis of said projectile guide tube, for receiving a main propellant charge, and window means, normally completely obturated by a projectile fully seated in said guide tube and located at a position removed from each end of said propellant charge receiving means, providing communication between said guide tube and said main propellant charge receiving means so that combustion of a propellant charge in said propellant charge receiving means commences in two different directions only after projectile movement has occured sufficiently to uncover said window means.
Claim 3
Dependent Claim
28 words
The casing of claim 1 including means at the periphery of said casing for releasing pressure generated by main propellant charge combustion to the volume about said casing.
Claim 4
Dependent Claim
23 words
The casing of claim 2 wherein said pressure releasing means comprises reduced thickness portions of said casings which are ruptured by such combustion.
Claim 5
Dependent Claim
29 words
The casing of claim 2 wherein said pressure releasing means comprises at least one opening therein covered by a releasable cover, about which combustion gases under pressure may pass.
