The .454 Casull (/ k ə ˈ s uː l /) [4] is a firearm cartridge, developed as a wildcat cartridge in 1958 by Dick Casull, Duane Marsh and Jack Fullmer. [5] It was announced in November 1959 by Guns & Ammo magazine. The design is a lengthened and structurally improved .45 Colt case. [5]
Buffalo Bore's loading for the .500 S&W cartridge offers much less energy at the muzzle, achieving only 2,579 ft⋅lbf (3,497 J) by driving a 440 grain .500 caliber bullet at 1,625 ft/s (495 m/s). [ 8 ] [ 9 ] However, the claimed muzzle energies of ammunition manufacturers may not be realized in real-world firearms, due to differences in ...
The basic design of the Model 460 is based on another X-frame revolver, its counterpart, the Smith & Wesson Model 500, a .50 caliber revolver. [2] [4]Aside from the .460 S&W Magnum cartridge, the revolver can also chamber .454 Casull, .45 Colt, and .45 Schofield ammunition.
Dick Casull with a rifle. Richard J. Casull (/ k ə ˈ s uː l /) (February 15, 1931 – May 6, 2018) [1] was an American gunsmith and wildcat cartridge developer whose experiments with .45 Colt ammunition in the 1950s led to the creation of the .454 Casull cartridge.
For many years, the small Wyoming manufacturer Freedom Arms was the only substantial maker of guns for the cartridge. In the mid-1990s, two major manufacturers, Ruger and Taurus, started selling guns chambered in .454 Casull because it was popular due to its extreme power. It was finally commercialized in 1997 when SAAMI published its first ...
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]
The Super Redhawk was already the only 6-shot .454 Casull revolver in production, as all other makers used 5-shot cylinders to keep the cylinder walls thicker to handle the high pressures. The .480 Ruger uses lower pressures than the .454 Casull, at 48,000 psi , [ 5 ] [ better source needed ] so the .454 Casull can produce higher velocities and ...
Any .454 Casull revolver will chamber and fire the .45 Colt and the .45 Schofield, but not the inverse due to the Casull's longer case. The .460 S&W Magnum is a longer version of the .454 Casull cartridge. Likewise, .460 Magnum revolvers can chamber and fire the three shorter cartridges, but again, not the reverse.
