The .44 Remington Magnum, or simply .44 Magnum, is a large-bore cartridge originally designed for revolvers. After introduction, it was quickly adopted for carbines and rifles. Despite the ".44" designation, all guns chambered for the .44 Magnum case, and its parent case, the .44 Special, use bullets of approximately 0.429 in (10.9 mm) diameter.[3] The .44 Magnum is based on a lengthened .44 Special case, loaded to higher pressures for greater velocity (and thus, energy). The .44 Magnum has since been eclipsed in power by the .454 Casull, among others; nevertheless, it has remained one of the most popular commercial large-bore magnum cartridges.[4][5] When loaded to its maximum and with heavy, deeply penetrating bullets, the .44 Magnum cartridge is suitable for short-range hunting of all North American game—though at the cost of much recoil and muzzle flash when fired in handguns. In carbines and rifles, these are non-issues.
