    I am having the stock replaced and the action bedded. I am considering asking him to lap the lugs and bolt face to "true" the action. I am getting mixed reviews with all that I have asked. I asked this question over on one of the hunting forums but thought it would be better suited here.

    Lapping is always a good idea to improve the fit, But it can increase head space and effect brass
    life if head space is not correct.

    Normally this is part of the truing process and is done before the barrel is fitted.

    Look at the back surface of the recoil lugs on the bolt and if they are both in contact at least
    50%+ you are probably ok (Not desirable but ok).

    If your smith will set the shoulder back and re head space then true the entire action.

    i looked at that, it does seem to have a pretty good contact patch on the lugs. the rifles shoots very well. groups at .3 at 100 with 36gr varmint grenades and .5 at 100 with 52gr BTHP. So, based on your info and my experience, I think I will elect to skip the action work and just have the stock installed and bedded.

    So, with that being decided. Should we pillar bed or glass bed or both?

    I allways do both.

    Install the pillars and do a full bed. (Take no chances) and this way you wont be second
    guessing your self later as to whether you should have or not.
