The 9mm High-Standard was an experimental cartridge developed by the High Standard Manufacturing Corporation of Hamden Conn. The case is a standard 9mm Parabellum case, but it used a sintered iron bullet as can be seen in the middle specimen. Trials were done for the US Government, but results are not known. (Erlmeier, Brandt Ref. 126).
