12.7x108mm Ammo

12.7x108mm Ammo For Sale From Various Ammo Vendors

The 12.7×108mm cartridge is a 12.7 mm heavy machine gun and anti-materiel rifle cartridge used by the former Soviet Union, the former Warsaw Pact, modern Russia, China, and other countries.

It is used in the same roles as the NATO .50 B.M.G. (12.7×99mm NATO) cartridge. The two differ in bullet shape and weight, and the casing of the 12.7×108mm is slightly longer, and its larger case capacity allows it to hold slightly more of a different type of powder.

According to guidelines, the 12.7×108mm case can handle up to 360 MPa (52,213 psi) piezo pressure. In C.I.P. regulated countries, every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to consumers.
