摘要： The present invention is an improved .30 caliber cartridge that overcomes the limitations of the prior art by providing a centerfire cartridge with a case having a head with a rim, a body extending from the head to a tapered shoulder to a mouth that seats a bullet. The cartridge having a dimension that is short enough to fit in an automatic pistol's magazine and when fired from such a pistol's barrel will achieve ballistics closely resembling that of a rifle carbine.

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.

摘要： An ammunition tracking system. The ammunition tracking system comprises a server having a data storage. The server is configured to receive data corresponding to a symbolic encoded identifier marked on ammunition, receive data corresponding to a purchaser of the ammunition, associate the data corresponding to the symbolic encoded identifier with the data corresponding to the purchaser of the ammunition, receive data corresponding to a retrieved ammunition casing, and compare the data corresponding to the retrieved ammunition casing with the data corresponding to identification of the ammunition. Upon matching the data corresponding to the retrieved ammunition casing with the data corresponding to identification of the ammunition, the server is configured to transmit the data corresponding to the purchaser of the ammunition.

摘要： The present invention provides an ammunition disabler with a material capable of being selectively changed in response to an energy wave for preemptively disabling ammunition. In at least one embodiment, the ammunition disabler includes a material selectively structurally changeable from an operative state to a deactivated state upon exposure to an energy wave is provided, where the material is positioned at least partially between the firing pin and the priming compound when the ammunition is chambered within the firearm (with the priming compound positioned between the material and the propellant), and related systems, methods and uses. The material may be contained within the primer cup with the priming compound. The material may be positioned adjacent to the priming compound in direct or indirect contact or in close proximity. The material may be positioned externally from the primer cup.

摘要： A gas propelled munitions anti-fouling system has a case having an open forward mouth end, a rear end, and an interior, the rear end defining a pocket that receives a primer and a passage communicating between the pocket and the interior of the case, a quantity of propellant received within the interior of the case, a quantity of anti-fouling composition received within the interior of the case, and a bullet having a rear portion inserted into the open forward mouth end of the case. The anti-fouling composition may have at least one salt and at least one acid. The acid may be anhydrous. The salt may be sodium chloride or sodium nitrate. The acid may be anhydrous citric acid. The anti-fouling composition may have at least one abrasive. The abrasive may be stannic acid. The anti-fouling composition may be 50% salt by weight and 50% acid by weight.
