From left to right: .450 Adams, .455 Webley Mk I, .455 Webley Mk II cartridgesOriginally loaded with 13 grains (0.84\u00a0g) of black powder under a 225-grain (14.6\u00a0g) bullet,[2] it was later also offered in a smokeless powder loading.[2] Despite the different designations, the .450 may be fired in any weapon chambered for .455 Webley,[2][3].455 Colt, or .476 Enfield.[4]While not considered a suitable military round,[2] the .450 Mark III cartridges did serve in reserve for the British armed forces as late as the First World War.[2]The .450 Adams also proved popular among civilian users of Webley RIC and British Bulldog revolvers, being loaded in Europe, and persisting in the United States until around 1940. Both Colt and Smith & Wesson offered revolvers in .450 Adams.[2]It was roughly similar in power to the contemporary .38 S&W,[5].41 Colt,[6] and .44 S&W American.[7]Handloaded ammunition can be made from shortened .455 Webley brass.Dimensions[edit]Adams Mk I.Adams Mk II.Adams Mk III.See also[edit]^ Maze, Robert J.
