The '''.454 Casull''' ({{IPAc-en|k|ə|'|s|u:|l}})<ref>{{cite web |url=https://forvo.com/word/casull/ |title=Casull pronunciation in German |access-date=2019-07-20}}</ref> is a [[cartridge (weaponry)|firearm cartridge]], developed as a [[wildcat cartridge]] in 1958 by [[Dick Casull]], Duane Marsh and Jack Fullmer.<ref name="COTW">{{cite book |last=Barnes |first=Frank C. |author2=Skinner, Stan |title=Cartridges of the World 12th Edition: A Complete and Illustrated Reference for Over 1500 Cartridges |publisher=[[Krause Publications]] |date=October 20, 2009 |page=568 |isbn=978-0-89689-936-0}}</ref> It was announced in November 1959 by ''[[Guns & Ammo]]'' magazine. The design is a lengthened and structurally improved [[.45 Colt]] case.<ref name="COTW"/> The wildcat cartridge went mainstream when Freedom Arms brought a single action five-shot revolver chambered in .454 Casull to the retail firearms market in 1983. [[Ruger]] followed in 1997, chambering its [[Super Redhawk]] in this caliber. [[Taurus (manufacturer)|Taurus]] followed with the [[Taurus Raging Bull|Raging Bull]] model in 1998 and the [[Taurus Raging Judge Magnum]] in 2010.
The [[.45 Schofield]] and .45 Colt cartridges can fit into the .454's chambers, but not the other way around because of the lengthened case (very similar to the relationship between [[.38 Special]] and [[.357 Magnum]] cartridges, as well as the [[.44 Special]] and [[.44 Magnum]] cartridges).<ref name="COTW"/>

==Specifications==
The .454 Casull was finally commercialized in 1997, when [[SAAMI]] published its first standards for the cartridge.<ref name=chuck>{{cite web |url=http://www.chuckhawks.com/454casull.htm |title=.454 Casull |author=Chuck Hawks |access-date=2007-11-14}}</ref><ref>{{cite web |url=http://www.reloadbench.com/cartridges/p454c.html |title=.454 Casull |access-date=2007-11-14 |archive-url=https://web.archive.org/web/20071106034845/http://www.reloadbench.com/cartridges/p454c.html |archive-date=2007-11-06 |url-status=dead }}</ref><ref>{{Cite web|url=https://www.shootingtimes.com/editorial/the-fascinating-454-casull/99489|title=The Fascinating .454 Casull|date=28 March 2018}}</ref> The new Casull round uses a small rifle [[Primer (firearm)|primer]] rather than a pistol primer, because it develops extremely high chamber pressures of over 50,000 CUP ([[copper units of pressure]]) (410 [[pascal (unit)|MPa]]), which are rifle levels of pressure. It requires the use of a rifle primer to withstand those significantly greater pressures, blurring the distinction of it being a pistol or a rifle cartridge.<ref>{{cite book|page=50|title=Handbook of Handguns|author=Jeffrey Strickland |year=2013|isbn=9781300973294}}</ref>

The round is one of the most powerful handgun cartridges in production.<ref name="COTW"/> The .454 Casull generates almost five times the recoil of the .45 Colt, and about 75% more recoil energy than the .44 Magnum.<ref name=chuck /> It can deliver a 250 grain (16 g) bullet with a muzzle velocity of over 1,900 feet per second (580 m/s), developing up to 2,000 [[Foot-pound force|ft-lb]] (2.7 [[kilojoule|kJ]]) of energy from a handgun. One Buffalo Bore loading drives a heavier, 300 grain, JFN bullet at 1,650 ft/s for 1,813 ft-lb of muzzle energy.<ref>[https://www.buffalobore.com/index.php?l=product_list&c=11 Buffalo Bore Ammo - .454 Casull Pistol & Handgun Ammo]</ref> The .454 Casull round is primarily intended for hunting medium or large game, [[metallic silhouette]] shooting, and bear protection.<ref>{{cite book|pages=11, 125|title=Handgun Hunting: How to Travel the World in Pursuit of Wild Game!|author=Mark Hampton|publisher=Krause Publications|isbn=0-87349-364-8|year=2002}}</ref><ref>{{cite book|title=50 Guns That Changed the World: Iconic Firearms That Altered the Course of History|author= Robert A. Sadowski|publisher=Skyhorse|year=2015|isbn=978-1634504454}}</ref>

The Casull cartridges were originally loaded with a triplex load of propellants, which gave progressive burning, aided by the rifle primer ignition, resulting in a progressive acceleration of the bullet as it passed through the barrel.<ref name="COTW"/>

The first commercially available revolver chambered in .454 Casull was made by [[Freedom Arms]] in 1983 as a five-shot single action Model 83 revolver that is capable of firing [[.45 ACP]], [[.45 Colt]] and .454 Casull with interchangeable cylinders.<ref name="COTW"/> The [[.460 S&W Magnum|.460 Smith & Wesson Magnum]] cartridge introduced in 2005 is a lengthened .454 Casull cartridge and has the same diameter as a .45 Colt or .454 Casull. Therefore, revolvers chambered for .460 S&W will also chamber .454 Casull, [[.45 Colt]], and [[.45 Schofield]] (.45 Smith & Wesson).<ref>{{cite book|title=Shooter's Bible, 111th Edition|year=2019|author=Jay Cassell |isbn=9781510748149|publisher=Skyhorse Publishing}}</ref>
