Patent attributes
One embodiment of the present invention provides a polymeric ammunition comprising: a substantially cylindrical insert; a substantially cylindrical polymeric middle body comprising a substantially cylindrical polymeric bullet-end opposite 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 an circumferential surface and into the primer flash hole aperture to form a primer flash hole; and a substantially cylindrical open-ended polymeric bullet-end component connected to the substantially cylindrical polymeric bullet-end and opposite a bullet-end aperture; a propellant at least partially filling the powder chamber; a primer inserted into the primer flash hole aperture; and a bullet frictionally fitted in the bullet-end aperture, wherein the primer, the propellant and the bullet form a sealed propellant chamber.
