摘要： Die Erfindung betrifft eine Treibladungshülse aus Stahl, bei der die Wandstärke (d) des Schulterkonus (4) gegenüber der Wandstärke (d'') des Hülsenkörpers (1) im zum Schulterkonus (4) benachbarten Bereich im Zehntelmillimeterbereich verringert ist. Hierdurch werden Verschlußklemmer beim Verschießen der Munition verhindert.
摘要翻译：本发明涉及一种由钢组成的推进剂充电套管，其中肩锥体（4）的壁厚（d）相对于壁厚减少了十分之一毫米的量（壳体（1）的相对于肩锥（4）的区域中的“d”。这样可以防止在射击期间弹药在枪毙中受到干扰。

摘要： Beim Einführen von Patronen in eine Waffe besteht die Gefahr, dass dabei der Schulterkonus (14) der Patronenhülse (10) in unerwünschtem Masse deformiert wird. Zur Vermeidung dieses Nachteiles wird erfindungsgemäss die Wand des Schulterkonus' (14) dicker als die Wand des Hülsenkörpers (13) der Patronenhülse (10) ausgebildet. Zur Herstellung einer solchen Patronenhülse (10) wird ein Extrudierdorn (16) verwendet der im Bereich des Schulterkonus' (14) eine Aussparung (17) aufweist, zur Erzeugung einer Verdickung (18) in der Wand der Patronenhülse (10).

摘要： 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.

摘要： A double shoulder angle firearm cartridge for AR-15, bolt action rifles, pistols, and any other firearm includes a firearm cartridge comprising a case that holds a primer, powder, and bullet. The case is defined by a case head forming a rim and an extractor groove, a body section extending from the case head, at least two shoulder angles extending from the body section, and a neck section extending from the shoulder angles. The shoulder is defined by at least two angles tapering into each other in an integral configuration. The first angle is 30°; and the second angle being a 17° 30′ shoulder angle, substantially the same as the 7.62×39 Russian round. The diameter of the case is approximately 0.447 inches. The length of the case is approximately 1.530 inches.

摘要： A separate-loading firearm uses a battery-powered electric resistance heating element to ignite a propellant charge. Both ignition reliability and ballistic reproducibility are enhanced when a first portion of the propellant charge is consistently and firmly packed into a cavity formed in a rear surface of a bullet. This first portion may be sealed in the cavity by a membrane. A second portion of the propellant charge is packed within a firing chamber so that it abuts both the heating element and the first portion of the propellant charge.

摘要： The rifle system comprises a rifle and an ammunition round for operation with the rifle. The high pressure ammunition round further comprises a cartridge case having an outer wall wherein prior to firing of the ammunition round, the outer wall geometry of the cartridge case is devoid of features configured for interfacing with a mechanical extractor. The rifle further comprising a barrel chamber which fully supports a chambered cartridge case and a rear extraction mechanism for extracting a spent cartridge case through the rear of the barrel chamber.
