A cartridge case 64 for a cased telescoped ammunition round 10. Cartridge case 64 includes a casing 12 having inwardly tapering conical end portions 14, 16 and end seals 20, 22 which undergo elastic deformation when round 10 is fired from a gun. A plurality of spring fingers 62 are formed on portions 14, 16. Conical portions 14, 16 fit into seals 20, 22. Casing 12 is secured to seals 20, 22 by the tips 66 of spring fingers 62 fitting into catch grooves 56, 56′of seals 20, 22. A control tube 24 is secured to rear seal 20 and a primer 30 is mounted in control tube 24. Projectile 26 is mounted within round 10 with its piston 28 located within control tube 24. Main propellant charge 36 is positioned around control tube 24 and round 26. A booster charge 32 is positioned with control tube 24. Axial growth of casing 12 compresses spring fingers 62 retract end seals 20, 22 after firing. Radial expansion of cartridge case 64 is accommodated by elastic deformation of the casing.
