If you decide that you want to fire-lap that barrel to help clean up some of the pitted roughness, let me know. For the cost of postage and a little to off-set the lapping paste, I will fix you up with 20 lapping rounds. All you need to do is clean and dry the barrel. Then shoot these using a light 30 grain charge, cleaning and drying between shots and it should clean up very nicely. You would be amazed at the difference it can make in a mass-produced barrel, esp. one that has had some rust damage. The target I posted was post-fire lapping. Prior to that if I hit a pie pan at 50 yards I was doing well.
