12.7x55 is a heavy .50 caliber round developed for close quarter operations against heavily armoured opponents. Ammunition varies from 100 grain to 2000 grain loads all capable of packing variably harder punches the heavier the round is. The 12.7x55 ASh performs poorly at range and is generally unable to reach out further than 300 meters.
