Abstract
A cartridge is described having a cartridge casing (1) and having a propellant cup (4), which is inserted in the cartridge casing (1), receives a sub-caliber projectile (5) in a formfitting manner, and is manufactured from plastic, and which separates the projectile (5) from the propellant charge in the cartridge casing (1) and has axial separation points (15) along its jacket (10). To ensure an advantageous length for the projectile, it is suggested that the propellant cup (5) have at least one pocket (9), extending in a cavity between the projectile (5) and the cartridge casing (1) and/or in a cavity of the projectile (5) and open toward the base (2) of the cartridge casing (1), for receiving a part of the propellant charge.

A cartridge comprising:
- (a) a cartridge casing comprising a base;
- (b) a propellant cup manufactured from plastic and inserted in the cartridge casing, said propellant cup comprising a jacket having axial separation points along the jacket;
- (c) a sub-caliber projectile received within the propellant cup in a formfitting manner;
- (d) a propellant charge disposed in the cartridge casing and separated from the projectile by the propellant cup;
- and
- (e) a cavity between the projectile and the cartridge casing;
- wherein the propellant cup comprises at least one pocket for receiving a part of the propellant charge, said at least one pocket extending into the cavity between the projectile and the cartridge casing, being open toward the base of the cartridge casing, and being delimited on one side by at least one inner wall of the propellant cup, the at least one inner wall pressing against the projectile and extending alongside the projectile in an axial direction.
