Modular cartridges are disclosed that can be initially assembled, disassembled, and reprocessed by hand. The cartridge case is suitable for use with a variety of projectile designs and weights and for use with a range of propellant amounts and primer types. The variety of projectiles and range of propelling forces permits the present invention to provide cartridges for all types of uses, including indoor and outdoor target shooting, training, non-lethal self-protection, and lethal uses. The cartridges include a case, a projectile, a primer, and a selectable amount of propellant (if any), and primer housing insert” and which is configured to be releasably attached to the striking end of the case and to contain the primer and the desired amount of propellant.

A radar-absorbing material projectile system including a projectile with an outer layer of radar-absorbing material (RAM). A carrier or armature is disposed around the projectile, protecting the layer of RAM during the firing sequence. In some embodiments the carrier is a discarding carrier which falls away after firing, rendering the projectile low-observable with regard to radar detection due to the layer of RAM.

A method and apparatus for acidizing and perforating simultaneously.

A rifled barrel has a cylindrical channel longitudinally extending within the rifled barrel between an oppositely oriented muzzle opening and a breach opening, the cylindrical channel having a rifled portion and a non-rifled portion, the rifled portion having a land and a groove helically extending along a surface of the cylindrical channel from the muzzle opening toward the breach opening, the non-rifled portion being smooth and having a consistent diameter along a length. The diameter of the non-rifled portion of the cylindrical channel is equal to a diameter of the rifled portion measured between oppositely oriented sections of the groove. A transitional section of the rifled portion has a diameter measured between oppositely oriented land sections that gradually decreases along a section of the rifled portion adjacent to the non-rifled portion until equaling the diameter of the non-rifled portion.

A nonlethal projectile includes a payload for immobilizing and/or identifying a target. The projectile is capable of separating or otherwise opening after launch by a launcher to release the payload prior to impact with a target. The launcher is capable of initiating separation of the projectile. Opening may also be accomplished by a control circuit with a radio-frequency identification (RFID), where an RFID tag in the projectile causes the projectile to open at a specified distance from the launcher. The launcher may include a trigger and/or a safety switch to prevent the projectile from becoming armed until a certain parameter is met. A magazine or breech assembly of the launcher may energize the projectile prior to launch of the projectile.

The ballistic element is made with a main body of non-metallic material, such as, from filaments of glass, aramid, carbon and basaltic fibers. The ballistic element also has heads of metal at opposite ends of the main body. A tubular liner of plastic may be disposed with the main body about an axial cavity for a detonating charge. The main body may also have one or more inserts for receiving one of an anchor bolt and a suspension component of an aircraft for use of the element as an aircraft bomb.

A novel castable frangible projectile and techniques for manufacturing such are provided. A cartridge system includes a case defining a volume, a propellant disposed in the volume of the case, and a projectile coupled to the case. The projectile includes a body disposed at least partially within the case and configured to enclose the propellant within the volume of the case. The body is formed of a castable eutectic mixture, the castable eutectic mixture configured to be melted and cast, wherein the body is configured to break into a plurality of fragments upon impact with a target.
