I just picked up a Ruger Redhawk 45 Colt and like many of the Rugers in this chambering it's cylinder throats are undersize of the bore. The bore is .452 and the cylinder throats range from .4512-.4517. I am wanting to have the cylinder throats opened to .4525. I've no intentions of running anything other than cast bullets in it. Are there any revolver smiths in the Anchorage/Matsu area who can do this work. Also looking for a trigger job on the same gun while I'm at it. Thanks in advance.
