The .357 Smith & Wesson Magnum, .357 S&W Magnum, .357 Magnum, or 9×33mmR (as it is known in unofficial metric designation) is a smokeless powder cartridge with a 0.357 in (9.07 mm) bullet diameter. It was created by Elmer Keith, Phillip B. Sharpe,[2] and Douglas B. Wesson[2][3] of firearm manufacturers Smith & Wesson and Winchester.[4][5] The .357 Magnum cartridge is notable for its highly effective terminal ballistics.
The .357 Magnum cartridge is based upon Smith & Wesson's earlier .38 Special cartridge. It was introduced in 1935, and its use has since become widespread.[6]
