Overview
The .460 S&W round is a lengthened, more powerful version of the popular .454 Casull, itself a longer and more powerful version of the .45 Colt. Consequently, firearms that fire .460 S&W are usually capable of firing the less powerful .454 Casull and .45 Colt rounds, but this must be verified with each firearm's manufacturer. For instance, some lever actions are designed to handle cartridges within a certain length and bullet profile range. The reverse, however, does not apply: .45 Colt and .454 Casull handguns generally cannot safely fire .460 S&W rounds—nor can they even chamber the .460 S&W because of the longer case length. The length of the .460 S&W was intended to approximate that of the .500 S&W.[citation needed]
The .460 cartridge achieves high velocities by operating at pressures normally reserved for magnum rifle cartridges.
Performance
Smith and Wesson boasts that the .460 S&W is the highest velocity revolver cartridge in the world, firing bullets at 2330 ft/s. With Buffalo Bore's new loading, the .460 S&W can achieve nearly 2900 ft-lb of energy by driving a 360 grain bullet at 1900 ft/s.[3] For comparison .500 S&W Magnum offers slightly more energy at the muzzle, driving a 350 grain bullet at 1975 ft/s for a total of 3031 ft-lb.[4]
