The .454 Casull was finally commercialized in 1997, when SAAMI published its first standards for the cartridge. [6] [7] [8] The new Casull round uses a small rifle primer rather than a pistol primer, because it develops extremely high chamber pressures of over 50,000 CUP (copper units of pressure) (410 MPa), which are rifle levels of pressure ...

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.

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".
However, with bullets of 400 grains (26 g) and higher, the .480 Ruger starts to show more potential. The standard .44 Magnum powders, in similar amounts, will push a 400-grain (26 g) bullet at over 1300 ft/s (thus yielding a TKO factor around 35.28 vs. 34.62 for a 325 gr 454 Casull at 1,650 ft/s (500 m/s)).
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 .45 Colt became the basis for the much more powerful .454 Casull cartridge, with the .454 Casull having a slightly longer case utilizing a small rifle primer in place of the large pistol primer. 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.
