Since this is a place to post opinions, here goes....

I would suggest selling the Ruger and your two AHR's and sending Ryan Breeding a check for $10K for a 5 shot 505 gibbs on the Granite Mountain Arms action. He can color case harden the receiver for you to provide a beautiful results, and his stockwork is outstanding. Although a Ruger conversion is cheaper, I do not think it is worth the investment since it is more of a 'halfway' sort of project.
