5mm Clement

The 5mm Clement is a centerfire cartridge was designed in 1897 and produced for early self-loading pocket pistols such as the 1897 Spanish Charola-Anitua pistol and the 1903 Belgian Clement pistol. The steeply conical, bottle-necked case is semi-rimmed, but headspaces on the shoulder of the case. The long bullet was inadequately stabilized and tended to tumble in flight. The Charola-Anitua pistol was produced in very limited numbers, and Clement pistol production shifted to the .25 ACP cartridge after 1906.
