    Abstract: A reduced-energy cartridge for a chamber of a firearm includes a case and a sabot. The sabot is moveably attached to the case and supported for movement relative to the case from an unfired position to a fired position resulting from combustion within the combustion chamber. The cartridge further includes a sealing member that projects radially outward from the longitudinal axis and from the sabot. The sealing member defines a blowback boundary where the cartridge is configured to seal against an inner surface of the chamber of the firearm. A forward area of the cartridge and a rear area of the cartridge are separated by the blowback boundary. The sealing member is configured for releasably sealing against the inner surface of the chamber to regulate pressure at the forward area resulting from combustion within the combustion chamber.

    Abstract: A casing for use in a cartridge for a firearm comprises a sleeve and attached base. The sleeve has cylindrical portion with a mouth for holding a bullet and an opposing radially-running bulkhead from which extends a nipple that is secured within a passageway of the base by a lip at the nipple terminal end. There are one or more seal regions in the passageway. A sleeve is preferably made of austenitic stainless steel and there are differing hardness and magnetic properties along the sleeve length. Particularly for high pressure rounds, the bulkhead has a frusto-conical portion with one or more circumferential waves and mates with a conical depression in the surface of the base; optionally, a skirt around the periphery of the base provides support to the sleeve bulkhead. A base has a deep cannelure with a continuously curving groove bottom, enabling a base to be made of an iron alloy into which carbon is diffused to enable hardening, after machining.

    Abstract: Disclosed is a cartridge case for various caliber ammunition that consists essentially of a powdered metal and/or powdered metal alloy that is formed into the cartridge case through an injection mold processing. Also disclosed is a method for forming a cartridge case, which may include use of Metal Injection Molding ("MIM") processes to produce the cartridge case which retains a primer, propellant, and/or a bullet. The method can include metal injection molding an initial part, and also at least one of tapering and trimming the initial part to form the finished cartridge case. Further embodiments can include the use of Finite Element Method (FEM) analysis to develop an optimized MIM design.

    Abstract: Die Patronenmunition (1) besteht aus einem Geschoss (11) und einer dieses aufnehmenden Patronenhülse (10). Die Patronen der Munition sind in einem Gurt (31) magaziniert und werden aus dem Gurt mit Hilfe einer Entgurtungseinrichtung heraus gezogen und in das Schloss der Schnellfeuerwaffe überführt, sodass die einzelnen Geschosse (11) mit hoher Schussfrequenz aus der Schnellfeuerwaffe abgeschossen werden können. Um durch das Ausgurten der Patronenmunition die schlagartig auf einen Bodenflansch der Patronenhülse (10) ausgeübten Kräfte zu minimieren, ist in dem Bodenflansch (32) der Patronenhülse (10) zumindest eine Ausnehmung (33) vorgesehen, die die Biegeelastizität des Bodenflansches, z. B. durch Verringerung der Dicke des Bodenflansches, erhöht. Die Ausnehmungen (33) können z. B. als Rille (33a) oder als Reihe von Sacklochbohrungen (33b) ausgestaltet sein, die parallel zu dem Rand des Bodenflansches verlaufen.
