9×53mmR

The Soviet 9x53R rifle cartridge was designed for hunting in the USSR. It is a 7.62x54mmR necked up to accommodate a larger bullet. Two bullet types are available:
 * Type A - SP for hunting 250–500 kg animals
 * Type B - FMJ for hunting 70–250 kg animals

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) and, more important, higher maximum pressure - 340 MPa.
