I do not have any dogs in this race, but it peaked my interest and I ran a quickload virtural computer program for the load that you stated of 67.3 g of Reloader 22 and barnes original 220 g bullet. Quickload predicted that the chamber pressure from this load would be 49,294 psi, which is at least 3,000 psi above maximum allowable chamber pressure for a .348 Win cartridge.
