The Soviet 9x53R rifle cartridge was designed for hunting in the USSR. It is a 7.62x54mmR necked up to accommodate a larger bullet.[5] Two bullet types are available:[6]
Several rifles were designed for this cartridge: Los' (Moose), Medved' (Bear), VPO-103 and Saiga-9.
This cartridge should not be confused with 9.3x53R Finnish which has similar dimensions, but a slightly larger bullet (71.45 mm overall cartridge length)[7] and, more important, higher maximum pressure - 340 MPa.[8]
