Description: American loading of a popular British cartridge. Originally adopted in 1869, with a composite Boxer construction with iron head rivetted by the primer to a solid drawn straight sided brass case wall, the cartridge soon developed a reputation for being underpowered, and there were problems with the Adams and Tranter revolvers on issue. The front sight of the Adams was found to foul on the issue holster. Instead of modifying the holster, the front sight of the revolver was filed down, making it shoot impossibly high. They continued as general issue until c. 1882 when supplies of the more powerful Enfield revolver became available, but the .450 remained in use by the Royal Irish Constabulary, in Indian army cavalry units and in colonial police and prison service until the First World War, the last major Government contract for 170,000 cartridges being with Eley for a smokeless load in September 1914. As a civilian pocket revolver cartridge, however, the .450 enjoyed great success, not only in Britain and its Empire but throughout Europe, and it was also developed into a target cartridge to rival the .44 Russian.
