    摘要： An insert for a high strength polymer-based cartridge casing (400) can include an outside, an inside formed within the insert, and a back end (402) disposed at a rear of the cartridge casing. The back end includes a rim (406) and groove (404) disposed around the outside of the insert and a primer pocket disposed inside the back end. Also included is a front end, opposite the back end, having an overmolded area (408) disposed around the outside of the insert above the primer pocket and a basin, having a depth, formed inside the overmolded area. A flash hole (418) can be included inside the insert and communicating between the primer pocket (416) and the basin. The flash hole has a perimeter and a ring disposed around the perimeter of the flash hole, including a height starting at a bottom of the basin, disposed toward the front end, and less than the depth of the basin.

    摘要： The object of the invention is a plastic cartridge case with a barrier, especially for a projectile of small arms, such as a cartridge bullet of a rifle or a gun, wherein a body (1) of the projectile case is made of plastics or a similar material that allows a simple and cheap fabrication of a cartridge case and also allows formation of a barrier (2) within the body (1) of the cartridge case, which barrier forms two chambers (A, B), the size of which has influence on pressure height in the cartridge case and consequently on bullet velocity.

    摘要： A high strength polymer-based cartridge casing (100) includes an upper component of polymer (200) having a first end (220) with a mouth (208), at least a wall between the first end and a second end (304) of the upper component opposite the first end, a sleeve (230) extending longitudinally and radially about the wall, and at least one of an overlap portion (222) and an underskirt portion extending from the wall near the second end The lower component (300) is molded from a polymer and includes at least one of a tapered portion (306) and an outer tapered portion that engages at least one of the overlap portion and the underskirt portions, respectively, to join the upper and the lower components. Further, the sleeve reduces a volume of a propellant chamber formed by the wall. The reduced volume of the propellant chamber permits only enough propellant to propel a bullet engaged in the cartridge casing at subsonic speeds.
