A sealing ring obturates a propellant charge cartridge of an automatic firearm for caseless ammunition, in particular against an end face of a firearm element, in particular for a breech or a projectile cartridge. The sealing ring contains a sealing surface that can be brought into contact with the end face. The sealing surface contains a first region around an annular opening of the sealing ring and a second region around the first region. The second region is set back relative to a tangential surface to the first region. In addition, a propellant charge cartridge for an automatic firearm for caseless ammunition, has at least one of the sealing rings. The propellant charge cartridge preferably contains one or multiple, in particular two, propellant charge chambers, which are provided with a sealing ring on each of the breech side and the projectile cartridge side.

A weapon barrel of an automatic firearm is subject to bending oscillations during firing. A damping device is provided for damping the bending oscillations and to at least largely dissipate the kinetic energy of the bending oscillations by friction processes which are initiated by the bending oscillations, between two respective successive shots in the firing sequence.

A propellant charge for use for ammunition, in which the propellant charge is separate from the projectile, has a propellant charge substance which can be initiated by a fuse. In order to solve the problem of providing a propellant charge for use in a two-part munition, which on the one hand can be produced easily and at low cost and on the other hand does not present any risk of damage when mechanically loaded before use, it is proposed that a propellant charge casing be provided which surrounds the propellant charge substance, with the propellant charge casing being in the form of a plastic part which is composed of a non-combustible, temperature-stable plastic material.
