This old wildcat cartridge has been around for years. In terms of muzzle energy, it claimed over 10,000 ft pounds at the muzzle. P.O. Ackley's books had loading information on this and other cartridges. One must be very careful with Ackley's loading data as it was generally on the HOT side. I know this from experience as I built a 450 Ackley magnum and used his loading data. I had to back off the powder charge as it was really creating pressure problems.
