LEAD FREE, COMPOSITE POLYMER BASED BULLET AND CARTRIDGE CASE, AND METHOD OF MANUFACTURING

摘要

A lead-free, composite polymer based bullet and cartridge case, wherein the cartridge case is formed by matingly engaging a cylindrical body and a corresponding base. A belted cartridge case has a double wall design, which provides the cartridge with increased thickness, and in turn, a reinforced structure useful for withstanding breakage from an impact caused by high pressure loads. The belt is formed to have an inner diameter at a first end of the base that is larger than the outer diameter of any portion of the cylindrical body. A nested cartridge case allows the second end of the case to nest in a first end of the base at an engaging region.
