.476 Enfield
The .476 Enfield, also known as the .476 Eley, .476 Revolver, and occasionally .455/476, is a British centrefire black powder revolver cartridge. The Enfield name derives from the location of the Royal Small Arms Factory at Enfield Lock, the armoury where British military small arms were produced, while Eley was a British commercial brand. Used in the Enfield Mk II revolver, the Mk III variant was introduced by the British Army in 1881, supplanting the earlier .476 Enfield Mark I and II cartridges, which in turn had replaced the .450 Adams cartridges, all of which also used black powder propellant.
