The .45 Schofield / 11.5x27mmR, also referred to as .45 Smith & Wesson is a revolver cartridge developed by Smith & Wesson for their S&W Model 3 Schofield top-break revolver. It is similar to the .45 Colt cartridge, but with a shorter case and a larger rim. The. 45 Schofield will generally work in revolvers chambered for that cartridge; but the reverse is not true, since the .45 Colt case is longer. United States government arsenals supplied .45 Schofield cartridges for the Schofield revolver and the Colt Army revolver to help simplify their armament needs.[1]
