[edit] Overview
The .460S&W round is a longer, more powerful version of the popular .454 Casull, itself a longer and more powerful version of the .45 Colt. Consequently, firearms that fire .460S&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. The reverse, however, does not apply: .45 Colt and .454 Casull handguns cannot accept .460S&W rounds. If attempted, explosion and life-threatening injury may occur. The length of the .460S&W also makes it difficult if not impossible to chamber into smaller handguns.
[edit] Performance
The Smith and Wesson 460XVR (8 3/8") and 460V (5") are two revolvers designed to fire the .460S&W round. Smith and Wesson boasts that the .460S&W is the highest velocity revolver cartridge in the world, firing bullets at 2330 ft/s. With Buffalo Bore's new loading, the .460S&W can achieve nearly 2900ft·lbf of energy by driving a 360 grain bullet at 1900 ft/s.[3] This still falls short of the title "most powerful commercial handgun cartridge" as the .500 S&W Magnum drives a 350 grain bullet at 1975ft/s for a total of 3032ft·lbf.[4] However, the .460S&W is still generally considered the "better choice for North American big game than the .500S&W."[5]
