    Has anyone on this forum fire lapped their revolver? Or tuned their cylinder throats? I'm thinking about doing so on my Ruger Super Blackhawk .44 Mag.

    Using cast bullets with out lube . They are rolled and coated with a lapping compound grit starting out with 400, 600,800 and 1200 grit. Shooting x amount of 400 grit cleaning bore after firing then shooting next grit cleaning and repeating till you get the thread choke out of barrel and imperfections out of barrel. Have you ever lapped the valves on that old 283 or 327 back in the day, Some idea put using bullets with compound . If cylinder throats are opened to over cast bullet dia. and bore choke where barrel is screwed on to revolver frame groups will shrink. Some Rugers are prone to this I feel a good scoped .44 mag should hold under two inch groups at 100 yards off a sand bag. Also a good trigger job is a must Wolf springs smoothing out machine marking on triggers part.:):flag::flag::flag:
