Has anybody checked to see what steel and what hardening processes are used for the 460 Roland conversion barrels? Is it different from the steel/hardening used for the stock .45 ACP barrels?
I know that Ruger sometimes uses different steels for the same gun when chambered for different cartridges. For example, the Super Redhawk uses one steel for the .44 Magnum, but another for the .454 Casull. So, rechambering the .44 Magnum guns to the .454 cartridge will lose a lot of the margin that Ruger intended for safety purposes.
