.303 British ammunition originated as a black powder cartridge, and was first employed by the British military in 1888. The Lee-Metford rifle, later known as the Lee-Enfield rifle, was the first rifle chambered for the .303 British, which eventually advanced from being a black powder cartridge to using cordite, a smokeless powder. In over 70 years of service to the Commonwealth, the .303 British saw action in the Boer War, the Turkish War of Independence and both world wars.

British WWII fighter aircraft machine guns were built to fire the .303 – including the Vickers machine gun, Lewis machine gun, many bolt action military rifles, and civilian rifles including the Winchester Model 1895 and the Ruger No.1.

Bullets for this cartridge weigh between 150 grains and 180 grains, muzzle velocity ranges from nearly 2,500 to more than 2,700 feet per second, and muzzle energy varies between 2,400 and 2,600 foot pounds. Several manufacturers – including Federal, Remington and Winchester – still produce .303 British for civilians, which come as soft point, full metal jacket or hollow point. For the military, .303 British cartridges have been topped with FMJ bullets, armor-piercing and incendiary rounds, tracer bullets, and a special marking round that made a puff of smoke at the point of impact.

This rather heavy bullet moving at high speed makes it a great round for hunting nearly all North American game animals, including elk and moose. Military surplus rifles are available chambered in .303 British, and they are used for hunting in Africa and Australia for a diverse array of game. While the .303 British cartridge might not be the most popular, it remains a solid performer with good availability in nearly any corner of the globe.

    "I had not had a chance to fire until this weekend. I picked up a 1913 British 303 at a estate sale in very fine condition. Then I was not able it find any rounds so I located yall on the net . I received my rounds very quickly. After firing them the balance and accuracy of the rounds have a very high quality , and the value fell well in range I could buy bher in Texas "
