A cartridge case (76) for a cased telescoped ammunition round (10). Cartridge case (76) includes a hollow cylindrical outer casing (12) the axis (18) of which is also the axis of symmetry of round (10). The inner surface of outer casing (12) has a longitudinal groove (50) formed in it along which groove (50) outer casing (12) splits when round (10) is fired. A front seal (20) closes the front end of casing (12) and a rear seal (22) closes the rear end of casing (12). A hollow cylindrical control tube (24) is secured to rear seal (22) so that control tube (24) is symmetric with axis (18). Three bolts (52, 53, 54) which are made of a material having a yield strength greater than the maximum stress to which the bolts (52, 53, 54) are subjected when round (10) is fired interconnect front and rear seals (20, 22). After round (10) is fired, bolts (52, 53, 54) return to their initial length, so that the length of the cartridge case returns to its initial length, and seals (20, 22) confine the casing (12) between seals (20, 22) to maintain the integrity of the spent cartridge case (76). |
