A cartridge for a small arms weapon, comprising a cover for housing a projectile; a metal cap at a rear end of the cover; a propellant charge located inside the cover at the rear thereof; and a gas seal element located inside the cover adjacent to the propellant charge and having an annular sealing formation projecting rearwardly towards the propellant charge and being outwardly deformable on detonation of the propellant charge for sealing against an internal surface of the cover. The metal cap has a rim extending longitudinally over a portion of the external surface of the cover for supporting the cover where the sealing formation first seals against its internal surface.
