The 7.62x38mmR (also known as 7.62mm Nagant and Cartridge, Type R) is a unique ammunition cartridge designed for use in the Russian Nagant M1895 revolver.

A small number of experimental submachine guns, designed by Fedor Tokarev, were also produced in 7.62mm Nagant. None, however, were accepted into Soviet service. However, this gas-sealed round would be extremely effective for sound suppressed weapons.
