When first introduced in 1956 as a joint effort between Smith & Wesson and Remington, this revolver round was advertised as a most powerful handgun cartridge in the world. While it is no longer holds this title, being outperformed by a number of monstrous loads of larger caliber, it is still a formidable number, suitable for a number of applications including long-range target shooting, self-defense (especially against dangerous animals) and hunting. Several semi-automatic pistols and carbines (lever-action and semi-automatic) were produced over the years to fire this cartridge. Today it is still manufactured by a number of makers worldwide.
