Casull

The .454 Casull is a proprietary cartridge developed by Dick Casull and chambered by Freedom Arms in their five-shot revolver.

The .454 originated as a wildcat but is now available as factory ammunition. The cartridge cases are of thick wall construction and while .45 Colt cases can be chambered, they should never be reloaded with .454 data.

The pressure limits vary among the bullets listed below according to the bullet manufacturer's recommendation.

The .454 Casull represents about the maximum amount of power that can be managed in a revolver. This cartridge is not for the faint hearted. The maximum loads shown below are approved by Freedom Arms for use in their revolvers. Accurate No. 9 is the propellant of choice for factory ammunition. It is recommended that a tight crimp is used to maximize bullet pull for this cartridge.
