The Wizard is chambered in several high pressure offerings, 270 Win included which has the same SAAMI MAP as the Casull and 460 at 65kpsi, case head is just .008" larger on the Casull/460 and is straight walled vs bottlenecked, so I don't think it would be a problem, several members here have rechambered their 45 Colt BC carbines to 460S&W with no problems, myself included, I did mine by hand with a rented reamer, Bobby just did his to Casull and he's happy with his also.
