The .454 Casull generates almost five times the recoil of the .45 Colt, and about 75% more recoil energy than the .44 Magnum. [6] 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 ft-lb (2.7 kJ ) of energy from a handgun.
Model 444: .44 Magnum caliber, can also fire the shorter .44 Special. Model 444 Ultralite: Compact .44 with a 4-inch barrel. Blued and titanium finishes only. Model 454: .454 Casull caliber, can also fire the shorter .45 Colt. Model 513 (Raging Judge Magnum): .454 Casull, .45 Colt, .410 shot shell — six round cylinder
The .460 S&W round is a lengthened, more powerful version of the popular .454 Casull, itself a longer and more powerful version of the .45 Colt.For this reason, the .460 S&W Magnum can be considered an example of a "super magnum".
The inclusion of the 454 Casull chambering makes the gun one of, if not the, most powerful semi-automatic handgun ever produced. This chambering places the Mateba in comparison to firearms like the Wildey pistol chambered in .475 Wildey Magnum and .44 Mag examples of the AutoMag pistol.
It was not designed for higher pressures generated by cartridges such as .44 Magnum or .454 Casull; to prevent the use of such rounds, the firing chambers of the Judge cylinder are choked to prevent chambering rounds larger in diameter than .410 shotshells and longer than .45 Colt cartridges. [2]
Casull felt he could offer a more powerful version of the .45 Colt and .44 Remington Magnum and built a number of five-shot prototypes on Ruger Super Blackhawk frames. Freedom Arms was the first commercial producer of revolvers chambered in this caliber, the .454 Casull, in 1983. [3] This model is still manufactured today as the Model 83. [4]
Although not originally designed for handguns, several rifle and shotgun cartridges have also been chambered in a number of large handguns, primarily in revolvers like the Phelps Heritage revolver, Century Arms revolver, Thompson/Centre Contender break-open pistol, Magnum Research BFR, and the Pfeifer Zeliska revolvers.
The .480 Ruger is built on the same frame as the .454 Casull, and was introduced as a six-shot model. While the .480 Ruger is not loaded to the rifle-like pressures of the .454 Casull, the bigger (.475 caliber, 12 mm) bore allows the use of heavier bullets than the .454 Casull, making it a good choice for handgun hunting.
