    Is it worth getting an action trued and keeping your factory barrel?

    I have a Rem 700 270wsm and would like to eventually put a new barrel on it. In the mean time I'm wondering if I would see any difference in accuracy if I had a gunsmith true up the action and bolt put a new bigger recoil lug on there, keep the same barrel if I would see any improvement in accuracy.

    Thanks for the input.

    Normally , accuracy problems with factory rifles are the barrels. I would not recommend truing an action and not replacing the barrel at the same time.

    Truing an action does help especially if a quality barrel is on it. but the improvements will be slight
    and the cost is not worth the effort if you find out later that the barrel is no good.

    I have gone through and trued/blueprinted factory rifles and eventually replaced the barrel in order for the rifle to reach it's true potential .

    So with a factory barrel truing has very little effect but with a custom barrel it leaves little doubt
    as to it's importance.

    Just my opinion

    Not with the factory barrel.

    When a proper action truing job is done the threads are single point turned oversize to correct any misalignment with the bolt raceway. Once this is done the critical thread fit in the action barrel joint with the factory barrel is lost. A new barrel with a fitted set of thread is required to correct this.

    That said, action truing makes everything nice and square when you are rebuilding the rifle but this action alone would be hard to see on paper.

    It's late and just throwing this out quick but in order of importance.
    My accuracy hierarchy of needs is:

    1-Shooter, head on straight with proper concentration , mind free of distractions.

    2-Stress free stable two point rest, consistent hold, elimination or at least consistent cant and parallax, proper breath control and trigger pull straight in line to the rear. No side pressure to hold cross hairs on target. This stock pressure input affects the recoil and follow through pushing the shot off target. Not noticeable at shorter ranges and the farther you are shooting the more of an impact this has.

    3-Crown, aligned to curve in bore, sharp and clean

    4-Stock and Bedding, solid, stress free with barrel free floated forward of lug.

    5-Stable scope mounts with properly focused optics with enough magnification to show errors.

    6-Quality consistent ammunition. Also brass fits chamber to help hold bullet aligned to throat. Could write a book on the rest of this but if the above is in order a guy should be able to run a pretty nice group.

    7-Premium barrel, the heavier the better.

    8-Good fitting barrel to action threads. Smooth slop free. Should feel like a micrometer spindle when installing the barrel. Under the pressure of firing ideally they move as one.

    9-Chamber aligned to curve in bore. Gets the bullet engraving all the lands squarely.

    10-Last is action truing, heavy lug, bolt sleeves. The only thing the action is doing now is capping the end of the breech. I have no idea but I would bet a wooden nickel not one of the bullet manufacturers test barrels has a trued action.

    Thanks or the honest replies. I'll just wait until I get a barrel to get it trued.
