User:Trekphiler/.476 Enfield

The .476 Enfield Mk 3 (also known as the .476 Eley), .476 Revolver, and occasionally .455/476) is a British centerfire revolver cartridge.

Used in the Webley revolver, it was introduced in 1881 for the British Army, supplanting the 1880 .476 Enfield Mk 1, which replaced the .450 Adams. A black powder round, it was itself overtaken by the black powder-loaded .455 Webley Mk 1 in July 1891 and the smokeless-loaded .455 Webley Mk 4 in September 1894.

Using the same bullet as the .455 Webley Mk 1, the .476 was 0.05mm longer and used a charge of 18 gr (1.17 g) of black powder. It can be used in an British Army .455 service revolver, but not the Colt or Smith & Wesson models, which are liable to be slightly smaller-bore.


 * Oh, the two cartridges definitely interchange- according to my copy of Robert J. Maze's Howdah to High Power (Excalibur Publishing, 2002):


 * "The Mark I Cartridge was never made in any great quantity and most, if not all of the production was sent to India... The first two marks of ammunition for the Enfield Cartridges had bullet diameters of .455 inches... Commercially produced Mk III cartridges were marketed by Eley as the .476"... Enfield Revolvers are all too frequently referrred to as the .476 Enfield when in fact their bore diameters were .442", the same as the prior .450" Adams and subsequent .455" Webley revolvers"

And that's just one source. I'm sure I could probably poke around somewhere and find another one, but basically .476 Enfield is interchangeable both ways with both .450 Adams and .455 Webley Mk I black powder cartridges (ie, a gun chambered for one will fire the others).
