One embodiment of the present invention provides a polymeric ammunition cartridge and methods of making and using the same. The cartridge includes a substantially cylindrical insert connected to a substantially cylindrical polymeric middle body. The substantially cylindrical insert includes a top surface opposite a bottom surface and a substantially cylindrical coupling element that extends from the bottom surface, a primer recess in the top surface that extends toward the bottom surface, a primer flash hole positioned in the primer recess to extend through the bottom surface, and a flange that extends circumferentially about an outer edge of the top surface. The substantially cylindrical polymeric middle body includes a substantially cylindrical polymeric bullet-end and a substantially cylindrical polymeric coupling end connected by a powder chamber, wherein the substantially cylindrical polymeric coupling end extends over the substantially cylindrical coupling element and covers a circumferential surface of the primer flash hole.

The present invention provides a polymer nose for a polymeric ammunition cartridge having a generally cylindrical neck having a projectile aperture at a first end, a shoulder comprising a shoulder top connected to the generally cylindrical neck opposite a shoulder bottom, a side wall extending from the shoulder, a groove positioned around the side wall, a skirt connected circumferentially about the groove to extend away from the groove, wherein the groove and the skirt are adapted to mate to a polymer cartridge.

A high strength polymer-based cartridge having a first end; a neck disposed at the first end and a shoulder disposed below the neck to form a bottleneck cartridge. A second end is opposite the first end and an insert is engaged to the second end. A propellant chamber is formed between the shoulder and the insert and has a volume. An extension extends from the neck opposite the shoulder and a cap is formed on the extension, partially sealing the propellant chamber.

A fully automated, integrated, end-to-end synchronized and compact manufacturing system produces polymer or metal case ammunition. Manufacturing stations support case assembly, sealing (gluing/welding), final product inspection, cartridge packaging or binning, and loading. Station modularity facilitates rapid changeover to accommodate ammunition of differing calibers. Sensors and apparatus may be provided to place a manufacturing cell in a wait state until all components or materials are received in a preferred orientation for proper assembly. The system may join and use multipart cases, each including a lower portion with a head end attached thereto and at least one upper portion having a necked-down transition to the open top end. Elevator feeders, vibratory bowl feeders, and robotic pick-and-place feeders may be used to deliver components for assembly.
