Definitions for ".500 S&W"
The .500 S&W is a cartridge made by Smith & Wesson for use in revolvers and introduced in February 2003 at the SHOT trade show. Currently only a handful of models have been introduced that fire this massive caliber, including the X-Frame Model 500 revolver from Smith & Wesson, Magnum Research's "BFR" (Biggest, finest revolver), the Taurus Raging Bull and German Janz JTL-E 500. Each holds only five rounds to allow for thicker cylinder walls to accommodate the pressure generated by such a large and powerful cartridge.
