8x22mm Nambu

The 8 mm Nambu is a rimless, bottleneck handgun cartridge introduced in Japan in 1904 for the Type A Nambu pistol. It was also used in the Type 14 Nambu and Type 94 pistols, and the Type 100 submachine gun. It uses .320" bullets. Power is relatively low, with military loads developing about 200 foot pounds, comparable to the American .380 ACP and substantially weaker than contemporary military cartridges such as 9x19mm Parabellum and 7.62x25mm Tokarev. 8 mm Nambu production ceased after the end of World War II, as the weapons that fired it were removed from service. Some small-scale production has occurred at various times in the United States for use in captured Japanese pistols, but the expense of these rare cartridges makes handloading common among owners of 8 mm Nambu pistols.
