Casull

Casull is a surname of English-language origin. In firearms history, it is most closely associated with Dick Casull, an American gunsmith who, in the 1950s, helped develop the .454 Casull cartridge. Named for its designer, the .454 Casull is a high-powered revolver cartridge created to deliver substantially greater velocity and energy than earlier magnum rounds based on the .45 Colt. The cartridge achieved popularity among hunters and shooters seeking substantial stopping power and range, and it is typically chambered in large-frame revolvers. Various loading options exist, ranging in performance, but all emphasize high pressure and significant recoil.

Firearms chambered for the .454 Casull require sturdy, purpose-built designs and careful safety practices due to the cartridge’s power. The round is primarily used for big-game hunting and, in some contexts, for challenging defensive situations where maximum stopping power is desired. Its development and continued discussion are often cited in relation to handgun power and cartridge engineering.

Beyond the firearms association, Casull may appear as a surname in other contexts, but the most enduring and widely cited link is to the cartridge named after Dick Casull. The Casull name, in popular discourse, is thus largely synonymous with this high-powered handgun cartridge and its history.
