Cartucho .357 Magnum

Also known as
  • 357 Magnum
  • .357 Mag

El .357 Magnum es un cartucho estadounidense de revolver, de fuego central y con reborde, desarrollado a partir del .38 Special en la decada de 1930 y alargado para que sus cargas de mayor presion no pudieran introducirse en revolveres .38 Special estandar. Winchester sigue catalogando cargas de fabrica para el cartucho, SAAMI y C.I.P. publican normas de presion y dimensiones, y armas actuales de Marlin, Henry, Rossi y Ruger muestran la compatibilidad continua del recamarado con revolveres, fusiles y carabinas.
