      Lapping is a very dangerous process for most of us. It is controlled accelerated wear. It is best done with a tightly fitting lead plug with very mild abrasive using a rod. I used a tight fitting patch on a John Dewey plastic coated rod, using JB Bore Brite. Bore Brite is a very fine cleaning abrasive, much more fine than JB Bore Scrubber. When I used it, I only made about 6 or 7 passes with the rod before removing it and thoroughly cleaning the bore with Shooter’s Choice on a cloth patch. I then took the gun to the range to try it to see if it made any difference. It sometimes took a couple of sessions to do it. I have now done this on 5 or 6 guns. One was a failure. That was my Single Six. Accuracy was bad with it. After working it, it got worse, including keyholing .22 mag bullets. I sent it back to the factory for a new barrel. Now it shoots great. Go figure. Even after the lapping I continued to shoot a bunch of copper wash stuff to continue to smooth the barrel. I think I am pretty well through that. They all seem to shoot pretty well.

      Hi Tom
      You said in your post you had to lap the barrel on your Mark III pistols. How does that work and what do you lap them with.
      Thanks
