The rounds intended for machine guns are made into a continuous belt using metallic links. The .50 BMG cartridge is also used in long-range sniper rifles and anti-materiel rifles. A wide variety of ammunition is available, and the availability of match grade ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower quality rounds.
