History of 303 British Ammo

.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.

Although it is an imperfect round, the 303 British has seen a lot of action among the civilian population, particularly in Commonwealth countries but also in the United States and South Africa. Canadians use it to hunt just about anything that walks, crawls, or flies, except for bears.

    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

    Very accurate round and grain of bullet. 225 yard shot on huge doe (almost 200 pound hoof weight) and one shot deer ran almost 25 yards and we were field dressing the deer. Only regret was that no bucks were seen and end of day and season.
