Magnum

Introduced in 1935 by S&W for their large frame revolver, the .357 Magnum is based on the .38 Special case lengthened 1/10th of an inch so it could not be chambered in a standard .38 Special revolver.

The .357 Magnum was the most powerful handgun cartridge for nearly 20 years, until the arrival of the .44 Magnum. The .357 Magnum has been chambered in almost countless revolvers.

While it has been used successfully on deer, black bear, and even larger game animals, the .357 Magnum cannot really be recommended for these animals unless ranges are 100 yards or less and it is used by a skilled hunter. Within these limitations, it can be quite effective on deer-sized big game.

The .357 Magnum is easy to handload, even with cast bullets. There is a wide variety of cast bullet designs available to the handloader.

The SAAMI Maximum Average Pressure for the .357 Magnum is 45,000 C.U.P. or 35,000 P.S.I. (Note: Most of this data is new and has been reshot using Copper Units of Pressure.)
