8×22mm Nambu

The 8×22mm Nambu is a rimless, bottleneck handgun cartridge introduced in Japan in 1904. It was used in the Type A and B Nambus, Type 14 Nambu and Type 94 pistols, Tokyo Arsenal Model 1927, Type II machine pistol, Hino Komuro M1908 Pistol and the Type 100 submachine gun. It uses 8.2 mm (.320") bullets. Power is relatively low, with military loads developing about 280 J (200 foot·pounds), comparable to the American .380 ACP and substantially weaker than contemporary military cartridges such as 9×19mm Parabellum, .45 ACP, and 7.62×25mm Tokarev.
