    Up there in the Basics forum I mentioned a Remington that I may get rebarreled. I know it's fairly common to have the smith true up everything on the action before installing a shiny new barrel, but how crucial of a step is this? What kind of accuracy are we talking about here...an extra 1/4 moa? 1/8? This is a hunting rifle which I would like to get shooting 1/2-3/4 moa consistently. Is it worth the extra bucks to throw down on squaring the action or will a new barrel get me where I need by itself?

    This is just my opinion, but an accurate rifle is the combination of all good parts and components. Any one of these parts or components can hurt accuracy if not done correctly.

    To give you an amount of accuracy loss is impossible because there are so many reasons for a poor shooting firearm.

    Sometimes poorly machined parts can cancel each other out, but most of the time they only compound the problem.

    Example; You can have a perfectly machined barreled action with a custom barrel of the finest quality
    and If it is placed in a poor fitting stock or fed poor ammunition It still won,t shoot well.

    The best approach I have found is to use the best barrels, blueprint the action, Install a good quality stock with pillar bedding and then start working on the ammo/loads to get extreme accuracy.

    I have found that if you have all of this done correctly the firearm seems to be very forgiving, repeatable and will be very accurate if fed good ammo.

    It is much better to eliminate questions about what you should have done in the beginning by doing
    it right the first time In my opinion.

    JE Custom, do you have a feel for how many actions come to you, square with the world? How about the custom actions out there?

    I have yet to find one that didn't need something. (Even the custom actions).

    The two actions that I have found to be near perfect and needed very little work is most of the
    custom actions and the Mark 5 Weatherby.

    Custom actions should always be perfect or near perfect but they use the same machinery to build
    them as the factory builders do and the only real difference between them is the Quality control of
    the custom action builders.

    Does that little bit of quality loss mean anything to accuracy? I don't know the answer to that but
    as perfect as you can make them does seem to make a difference, At least in my mind. Straight, true, square and well fit always eliminates doubt.

    Thanks for the input. Sounds like if you're going to rebarrel it isn't worth the risk of leaving the action alone. After all, the main purpose of rebarreling is to gain accuracy.

    Exactly !!!

    If you do everything to make it near perfect you don't second guess what you should have done
    while working up loads if it doesn't shoot as well as you wanted.

    To make a rifle shoot well It is simply the process of elimination. So you start with the things that can be eliminated in the beginning.

    A quality blue print/Truing + a quality barrel can/will shoot well if installed in a good pillar bedded stock, good rings, bases and scopes, and fed quality ammo.

    That right there pretty much sums it up!
