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: 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).
