POLYMER AMMUNITION HAVING AN ALIGNMENT AID, CARTRIDGE AND METHOD OF MAKING THE SAME
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 powder compaction device comprising a drive motor; a compaction rod comprising a metering region; a first funnel-shaped device having a first funnel aperture aligning to allow the metering region to pass through; an ammunition cartridge fixture comprising a second funnel-shaped area having a second funnel aperture to allow the loading region to pass through the second funnel aperture and the compaction end in an ammunition cartridge shaped void; one or more metering reliefs, wherein each relief has a powder metering volume; a powder reservoir in communication with the first funnel-shaped area; a compaction controller to control the vertical movement of the compaction rod; a powder metering controller to control the amount of the powder delivered; and a loading controller to control the vertical movement of the metering region.

The present invention provides a two piece and a three piece primer insert for ammunition piece. Each of the individual pieces may be formed by punching, pressing, stamping, molding, milling, coining, or by additive manufacturing. The individual pieces may be joined by clinching, pressing welding soldering, sintering, adhesive gluing, staking, and iterative addition by forming one piece into another piece.
The present invention provides three piece primer insert for use in polymer ammunition comprising: an upper primer insert portion comprising an upper primer insert bottom portion, a substantially cylindrical coupling element extending away from the upper primer insert bottom portion; and an upper flash aperture that extends through the upper primer insert bottom portion, a lower primer insert portion in contact with the upper primer insert portion, wherein the lower primer insert portion comprises a lower primer insert top portion positioned adjacent to the upper primer insert bottom portion at a connection joint, a lower flash aperture positioned in the lower primer insert top portion and aligned with the upper flash aperture, and a primer recess that extends away from the lower primer insert top portion to an extraction flange and in communication with the lower flash aperture; and a connecting portion that secures the upper primer insert portion and the lower primer insert portion wherein the connecting portion comprises a connecting member positioned in the upper flash aperture and the lower flash aperture, an upper tab connected to the connecting member to extend away from the upper flash aperture into the upper primer insert portion, a lower tab connected to the connecting member to extend away from the lower flash aperture into the primer recess, and a flash hole that extends from the upper tab to the lower tab to connect the upper primer insert bottom portion to the primer recess.
The present invention includes a device for determining the force necessary for the separation of a bullet from an ammunition cartridge comprising a chamber housing having central bore extending from a lower housing end to an upper housing end and terminating at a upper aperture, wherein the central bore comprises a chamber diameter adapted to accept an ammunition cartridge and that the bullet partially extends from the upper aperture; a frustaconical shape shoulder in the central bore at the upper housing end to reduce the chamber diameter to mate to an ammunition cartridge shoulder; a neck that connects the upper aperture to the frustaconical shape shoulder adapted to accept an ammunition cartridge neck; a cartridge retention lip within the upper aperture adapted to contact an ammunition cartridge bullet aperture; a chamber mount adapted to connect the chamber housing and a testing device; a bullet securing device comprising a bullet securing end to secure the bullet and a bullet securing device mount adapted to connect to the testing device; a moving mechanism to move the bullet securing device away from the chamber housing; a sensor in communication with the moving mechanism to measure a force exerted by the moving mechanism; and a display in communication with the sensor to display and or record the force.
The present invention provides polymer ammunition, ammunition cartridge, ammunition case, and portions thereof having traditional and non-traditional cartridge shapes or profiles.
