The 9 × 64 mm are synonyms 9.3 × 64 mm Development Complete development history of this cartridge is unknown. It was probably originally developed by Barnaul as a hunting cartridge for large game in the Russian Central Asian republics where long distance shots at relatively large game are the norm, requiring a cartridge that fires a bullet with high sectional density for range and heavy weight for terminal effects. These characteristics make for an excellent long range sniper cartridge that bridges the gap between
7.62 × 54Rmm used in the SVD and V-98 rifles and the 12.7 × 108 mm cartridge used in the V-94 and V-96 anti-matérial rifles. Russian sales literature is now promoting this round for sniper use. As such the 9 × 64 mm falls only slightly below the 0.338 Lapua Magnum in terms of overall ballistics. Although listed as a 9 mm in the latest Russian military sales literature, the cartridge has been available as a hunting round for some years with the designation 9.3 × 64 mm. As the cartridge's bullet diameter is 9.28 mm, this is actually a technically correct designation. Description The 9 × 64 mm are rimless, Berdan primed cartridge with a tapered bottlenecked case. Both steel and brass cases have been shown in Russian literature and both full metal jacket and soft point bullets have appeared. The 9 mm bullet is a streamlined, boat tail design with a crimping cannelure. The FMJ steel cored military bullet is claimed to be capable of penetrating 10 mm or hardened steel at 200 m. This bullet has a cupro-nickel jacket with lead and steel core components. The forward core element is a pointed hardened steel penetrator, backed by a lead filler. There is a small air gap in the bullet's nose ahead or the steel penetrator. Accuracy is claimed to be within 10 cm at 200 m and within 12 cm at 300 to 500 m when fired from a 'Tiger Carbine'. Technical references retained in this configuration include 17.4 g, 16.7 g, 17 g.
