The Ultimate Guide to 454 Casull Ammo: Ballistics, History, and Best Rounds for Hunting & Defense
Overview of the .454 Casull
The .454 Casull is one of the most powerful handgun cartridges available, offering extreme velocity, deep penetration, and superior stopping power. Developed in 1958 by Dick Casull, Duane Marsh, and Jack Fullmer, it was designed as an enhanced, high-pressure version of the .45 Colt to handle heavier loads and increased ballistic performance.
First introduced to the public in the November 1959 issue of Guns & Ammo magazine, the .454 Casull gained popularity in the 1980s when Freedom Arms released the first production revolver chambered for it. Since then, major firearm manufacturers like Ruger, Taurus, and Magnum Research (BFR) have produced firearms chambered in .454 Casull, solidifying its reputation as the go-to caliber for big-game hunting and self-defense against large predators.
