Vickers, 303in Mark 1 Water-Cooled Machine Gun. This, the standard water-cooled weapon, remained in service for Great Britain until 1968. It was the medium machine gun used by all British Commonwealth forces in the Korean War, although Australian forces occasionally used the US .30 A4. Continuous automatic fire generated tremendous heat in the barrel and Maxim overcame this problem by encasing The barrel is encased in a water jacket, containing about 7.5 pints. Heat from continuous firing caused the water to boil, the steam indicating the gun's position. Attaching a tube from a vent in the jacket into a can of water condensed the steam and helped conceal the gun's position. The water-can also helped resupply the jacket, since there was an evaporation rate of about 1.5 pints per 1, 000 rounds fired. Operation Fully automatic, recoil operated, water-cooled Caliber .303in Ammunition Mk 8z ball; 174 gr bullet, 36.5 gr charge Muzzle velocity 2400 fps Capacity 250-round fabric belt, 22 lb. with box Weight Unloaded, 40 lb.
