The .500 S&W Magnum is a cartridge that was developed by Cor-Bon with the "X-Gun engineering team at Smith & Wesson for use in their Model 500 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. The single shot Thompson-Center Encore and NEF Handi Rifle are also chambered for this round.
