Re: uneven lug contact
Since you are a roll-yur-own guy a little more headspace shouldn't be that big of concern. If you don't already neck size your brass that is about the worst that could happen and really I don't think you would remove that much metal unless the lugs are waaay out of spec. I have only used lapping compound on action lugs once and that was a co-workers Rem 700 BDL 22/250Rem that had been re-blued by Remington. When he got the rifle back the bolt wouldn't hardly close. I suggested he make arrangements with their service dept. to fix it, but he begged me to see what I could do. It didn't take very long running the action with the compound in it to loosen it up just enough. Make sure to remove the compound when you have finished with it.
