ABSTRACT:
The case of a composite propellent charge cartridge exhibits cracks, after shooting, at the sharp transition of the extractor rim. This has a disadvantageous effect on the number of possible reloadings. The present case permits frequent reloading with little reconditioning. A rotationally symmetrical molding is placed on the case, and at least partially forms the extractor rim. The surface of the case that is in contact with the molding is rounded and smoothed at least at highly stressed points. The reusable cartridge case, with the molding, is suitable for composite propellent charge cartridges.
