revolvers chambered for the .475 Linebaugh. However, given their comparable operating pressures, the two rounds are far closer in performance than such a comparison would seem to suggest. The .475 Linebaugh remains a relatively obscure cartridge, owing in part to the commercial success of Smith & Wesson's more powerful .460 S&W Magnum and .500 S&W Magnum cartridges. However, while the .475 Linebaugh was once an exclusively custom proposition, both the Freedom Arms Model 83 and the Magnum Research BFR are currently available in the cartridge.
