The .460 Rowland / 11.43×24mm is a rimless, straight walled handgun cartridge designed in 1997[1] by Johnny Rowland and developed in conjunction with Clark Custom Guns as a derivative of the .45 ACP[2] with the goal of producing a cartridge which can achieve true .44 Magnum[3] ballistic performance and be fired from a semi-automatic platform. Despite its name, the Rowland is a true .45 caliber cartridge, like its parent.
