About the Cartridge

Smith & Wesson introduced this cartridge for its heavy-frame revolver. Ammunition was developed by Winchester in cooperation with Smith & Wesson. Using a lengthened and strengthened version of the .38 Special case, the .357 Magnum was rapidly accepted by hunters and law enforcement. At the time of its introduction, it was claimed to easily pierce the body panels of automobiles and crack engine blocks. While it has less power than the .44 Magnum, it compares favorably to the 10mm Norma and .45 ACP, but with better armor penetration. Today factories offer over fifty different loadings in this caliber.
