Are you currently having Accuracy issues? Accuracy is a byproduct of consistency. Consistency is not necessarily increased by swapping barrels. That said, barrels like Bartlien, Brux, Chriterion, Shilen, McGowen, Krieger & some others are all top shelf barrel makers. However, consistency does not come from simply installing a top shelf match grade barrel. It’s found through a coordinated system of parts that work together. And in conjunction with carefully worked up loads for that specific rifle.
