A case jacket made of a felted, in particular combustible fibrous material, comprising a cylindrical case jacket portion and a calotte-shaped case bottom which is connected to an end of the cylindrical case jacket portion, wherein the bottom-side end of the case jacket portion has a first inside diameter and a first outside diameter, and wherein the case bottom has an annular connecting edge towards the case jacket portion, which has a second inside diameter that is smaller than the first inside diameter, and a second outside diameter which is smaller than the second outside diameter, includes a conical connecting portion whose one end has the first inside diameter and the first outside diameter and is connected to the bottom-side end of the case jacket portion, and whose other end has the second inside diameter and the second outside diameter and is connected to the connecting edge of the case bottom, wherein the angle of inclination of the inner wall and the angle of inclination of the outer wall of the conical connecting portion with respect to the cylinder axis are not more than 10°.

The disclosure relates to an insert (5) made of a textile fabric for being received in a jacket wall of a cylindrical case (6) made of a combustible, felted fibrous material, wherein in particular embodiments the textile fabric includes one, several, or a plurality of yarns which along a longitudinal direction (L) of the insert form a plurality of mesh rows (18) which each include a plurality of meshes (19, 20, 21) that extend in a circumferential direction (U) of the insert.

A projectile with a projectile casing and at least one pyrotechnic charge incorporated in the projectile casing is proposed, wherein the projectile has an open projectile base with a destructible membrane and the pyrotechnic charge burns away at a defined rate during the flight of the projectile, and so the projectile loses mass in such a way that a predetermined effective range is not exceeded. As a result, safety and a nonlethal effect are achieved, in particular outside the effective range.

The invention relates to a combustible cartridge case (1) for ammunition, comprising a cylindrical envelope (2) intended to contain a propellant charge and to receive a projectile at a front end (AV). The cartridge case comprises, at a rear end (AR), a bottom (3) that is integral with the cylindrical envelope (2) and is intended to be positioned in a base. The cartridge case is characterised in that the bottom (3) comprises a combustible central ring (5) that is connected to a peripheral cup (4) by at least two combustible radial arms (6) delimiting openings (7).
