I picked up a replacement cylinder for my Super Blackhawk .44 Mag (going from non-fluted Dragoon Style to fluted style). It drops into the revolver and aligns all chambers to the bore perfectly, but seems a bit off regarding the gas ring to frame fit. With the cylinder held to the rear, the B/C gap is .005" and the gas ring/frame gap is .018". Pushing the cylinder forward, the B/C gap is .000" (actually contacts the barrel) while the gas ring/frame clearance is .013". I know I can always always use cylinder shims to maintain the proper gap of the barrel to the cylinder (maybe .003 - .004"), but are there other issues? I've worked on Ruger single actions for years without ever encountering this particular issue. Any ideas from any gunsmiths here or am I on the right track?
