Overall, the average velocity generated by the .454 Casull loads in the 7 1/2-inch barrel was 1742 fps with 1823 ft-lbs energy. In the 2 1/2-inch barrel the average velocity was 1497 fps with 1346 ft-lbs energy.
The most powerful SAAMI-spec commercial 240-grain .44 Magnum load fired in a 7 1/2-inch industry reference barrel generates 971 ft-lbs of energy (all heavier bullet .44 Magnum loads produce less energy than that). That gives the short .454 Casull Alaskan a 40-percent energy advantage over a long-barreled .44 Magnum.
