12.7x108mm (no ontology)

From Mazeworld

12.7x108mm is a rifle cartridge designed in the 1930s as a heavy machine gun and anti-matériel rifle cartridge. It was adopted in 1935 by the Soviet Union and its satellite states, being used in pretty much all of the same roles as that of its Western counterpart, .50 BMG. Despite that, both cartridges are quite different in terms of dimensions, with the 12.7x108mm bearing a longer, thicker case, and using a different projectile.

The cartridge was first employed in DShK heavy machine gun, in 1938. The first anti-matériel rifle chambered in 12.7x108mm was the KSVK.

In the Mazes, due to their extreme power, as well as the resulting cost of both firearms and ammunition, weapons chambered in 12.7x108mm are typically reserved for threats of exceptional nature.
