The .460 S&W Magnum round is a powerful revolver cartridge designed for long-range handgun hunting.

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 cannot generally or safely fire .460 S&W rounds. The length of the .460 S&W was intended to approximate that of the .500 S&W so revolvers designed to fire the .500 could be easily adapted to the .460.

The .460 cartridge achieves high velocities by operating at pressures normally reserved for magnum rifle cartridges. Gain twist rifling is utilized to limit forces on barrel and bullet as the bullet first engages the rifling.

Never fire a .460 S&W hand gun without proper hearing protection even when hunting in the field, the blast is too loud for the human ear even in an open field. The recoil from a standard 8 3/8" barreled model is manageable by most adults. Accuracy from the standard 8 3/8" model using the iron sights is excellent and rivals "brush" rifles such as a lever action .30-30.
[edit] 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 2900ft·lbf of energy by driving a 360 grain bullet at 1900 ft/s.[3] For comparison .500 S&W Magnum offers slightly more power driving a 350 grain bullet at 1975 ft/s for a total of 3031ft·lbf.[4] The .460 S&W will destroy small game animals. This cartridge should be reserved for hunting medium to large game (such as a deer, elk, hog, or moose) unless the hunter does not care about keeping the game animals after the shot.
