.454 Casull (New Brass) - Manufactured by Jamison Brass & Ammo
The .454 Casull was developed in 1957 by Dick Casull and Jack Fulmer. It was first announced in November 1959 by Guns & Ammo magazine. The basic design was a lengthened and structurally improved .45 Colt case. The .45 Colt cartridges can fit into the .454 Casull's chambers, but not the other way around because of the lengthened case. The .454 Casull round uses a small rifle primer rather than a pistol primer, because it develops extremely high chamber pressures of over 60,000 CUP. It is one of the most powerful handgun cartridges in production right now. It can deliver a 250 grain bullet with a muzzle velocity of over 1,900 ft/s, developing more than 2,000 ft-lb of energy. The round is primarily intended for hunting medium or large game, although is also used for metallic silhouette shooting and self-defense. The first commercially available revolver chambered in .454 Casull was made by Freedom Arms in 1983 as a five-shot revolver. Ruger began chambering its Super Redhawk in this caliber in 1997 and Taurus followed with the Raging Bull model in 1998 and the Taurus Raging Judge Magnum in 2010. The .460 Smith and Wesson Magnum cartridge has the same diameter as a .45 Colt or .454 Casull, and revolvers chambered for it will also chamber the .454 Casull, .45 Colt, and .45 Schofield.
