Response to Ok, understand lapping a little. I think.



Use as last resort but before recrowning. Lap from the breech end. Amount of paste -- enough to do the job. Hard to say. I first use JB on a patch with a crown saver from MAC1 pulled breech to muzzle. Then JB on a pellet if necessry. Finally, recrown the thing if nothing else works.



One thing I forgot. Should be No. 1 -- replace the trigger spring. Use a No. 4 or No 6 (almost too light - reinforce with drinking straw or some other type guide) from Ace Hdwe. Or cut one wind off the factory spring -- careful and measure, you can cut too much off. "
