This is not the place to discuss destroying the warranty on a revolver no one actually owns yet, nor is for sale in this thread. John and I discussed the fact that there will be folks wanting to ream these to .475. NEITHER of us think it's a good idea, and anyone who does will have no recourse with Ruger & Co. or McGrew Gun Works if they choose to do so. Nuff said. Let's please keep this .454 sales thread as just that
