  • The .357 Auto Magnum is a wildcat cartridge that is derived from the .357 Magnum. It is essentially a .357 Magnum cartridge that has been necked down to accept a 9mm bullet. This cartridge was designed to be used in a semi-automatic pistol, but it is not a standardized cartridge and is not commonly produced by ammunition manufacturers.

    The .357 Auto Magnum has similar ballistics to the .357 Magnum cartridge, but with a smaller bullet diameter. It is not widely used or recognized, and its use may be limited due to the lack of standardized production and availability of ammunition.
