Abstract: Ammunition cartridge including a rigid casing including a tubular sleeve and a base closing an end of the casing, a projectile mounted at another end of the casing, a propellant charge contained inside the casing, and an ignition device. The projectile includes a solid material body having a volume V1 extending between a tip to a trailing end, wherein the projectile further includes a cavity that extends into the body from the trailing end, a volume V2 of the cavity being at least fifteen percent (15%) of a combined volume V1+V2 of the projectile solid material and cavity: V2>0.15×(V1+V2).

Abstract: Ammunition cartridge (1) comprising a rigid casing (4) including a tubular sleeve (16) and a base (14) closing an end of the casing, a projectile (6) mounted at another end of the casing, a propellant charge (10) contained inside the casing, and an ignition device (8). The ignition device comprises an ignition charge (56) arranged to ignite the propellant charge at a point of ignition distal from the base (14) and proximal the projectile (6).

Abstract: A multi-part casing for an ammunition cartridge comprising a tubular sleeve and a base, the base assembled and fixed to the tubular sleeve by a weld arrangement. The base comprises an end wall having a rim, an extraction groove adjacent the rim, and a tubular extension extending from the end wall and having an outer surface in contact with an inner surface of a base end of the tubular sleeve. The welding arrangement comprises a weld line that spirals around the base end of the tubular sleeve from a weld line start point positioned over the tubular extension of the base spiraling to a weld line end section positioned over the extraction groove, a surface portion of the extraction groove interfacing with the tubular sleeve having a machined surface such that the weld line ends in the machined surface.

Abstract: The invention relates to a method for producing cases, in which a case sleeve is formed from thin sheets, forming at least one element over an insert, a form or a cavity reproducing the conicity, the shoulder and the mouth that are characteristic of the case. The invention also relates to a product produced by the method, such as an ammunition case.
