Re: Ruger #1 Re-chamber?
First, I am not sure any gunsmith will give you their normal accuracy guarantee being as it is a #1 and because it is using the factory barrel.
I do not know the west coast gunsmiths other than the ones on this site. If you want to drive it somewhere then Shawn Carlock is the closest and you could send him an email about it and see what he has to say.
Remember that the front quarter rib screw holes in the barrel have to remain lined up or else you are in big trouble so I would not let just any ole body do this work. You need somebody who will get it right or make it right.
