Multi-piece polymer ammunition cartridge nose

A polymer nose for a polymeric ammunition cartridge comprising:

• a generally cylindrical neck having a projectile aperture at a first end;
• an outer shoulder surface that extends from the generally cylindrical neck;
• an outer shoulder angle defined by the angle between the outer shoulder surface and the generally cylindrical neck;
• an inner shoulder surface on the inside of the polymer nose opposite the outer shoulder surface, wherein the inner shoulder surface extends to an inner side surface;
• an inner shoulder angle defined by the angle between the inner shoulder surface and the generally cylindrical neck wherein the inner shoulder angle is greater than the outer shoulder angle relative to the outer shoulder surface;
• a nose junction formed opposite the generally cylindrical neck at the outer shoulder surface, wherein the nose junction comprises a groove in the outer shoulder surface connected to an outer skirt surface that extends from the groove to a blunt skirt tip,
• wherein the nose junction is a half lap junction,
• wherein the outer skirt surface and the inner side surface meet at the blunt skirt tip, wherein a skirt angle is formed between the groove and the outer skirt surface is between 40 and 140 degrees,
• wherein the nose junction is adapted to mate to a polymer cartridge nose joint.
