.460 Rowland

The .460 Rowland is a lengthened cartridge based on the .45 ACP. It is more powerful than the .45 Super, and as such may be classified as a super magnum.

The cartridge is 1.322 inches long, almost $1/16$ inch longer than the .45 ACP. A revolver designed for the .460 Rowland can also fire .45 ACP, .45 Auto Rim, .45 Super, and .45 Winchester Magnum cartridges. With the exception of the .45 Auto Rim, all rounds require a moon clip for use in a revolver.

The increased length is designed to prevent the cartridge from being chambered in a firearm that is not designed for its use.
