.454 Casull Magnum
The .454 Casull was designed by Dick Casull
and Jack Fullmer and introduced during the mid 1950's. For many years, the
big .45 caliber cartridge was somewhat of a wildcat, but factory loaded
ammunition is now available from Freedom Arms of Freedom Wyoming, the same
company that manufactures the Casull single action revolvers in this caliber.
Unprimed cases with small primer pockets and custom bullets with extremely
thick jackets designed to withstand the tremendous stress they are subjected
to when fired from the .454 at maximum velocities are also available from
the firm.
In the muzzle energy department, the .454 Magnum produces about 50 percent
more punch than the
.44 Remington
Magnum. Of course, you'll find no free lunch here, the .454 churns up
close to 70 percent more recoil than the
.44 Magnum,
or about the same as a
.338 Winchester
Magnum in a 10 pound shoulder fired rifle.
For reduced velocity loads, the
.45 Colt can
be loaded in modern
.45 Colt cases
and fired in the Casull revolver, but only .454 Casull cases and Small Rifle
primers should be used when loading the .454 performance. H110 is one of
the few powders suitable for loading the .454 Magnum to maximum velocity,
and it does an excellent job. Jacketed bullets weighing 260 grains and less
and designed for use in the
.45 Colt work
equally well for reduced velocity .454 Casull Magnum loads, but they should
not be used in full power loads.
