Description
There are some obvious mechanical attributes that a barrel should possess if it is going to be a "tack-driver". These include the straightness of the hole, uniformity of the rifling geometry, and the twist rate. If the width of the lands or the depth of the grooves varies, that barrel is never going to shoot accurately. Likewise, if the interior finish of the barrel is poor then the barrel lacks the end-to-end uniformity required of an accurate barrel. A rough finish will also foul badly, causing accuracy trouble. And along with surface finish, the direction of the finish is very important too. Ideally the "lay" of the finish will be parallel to the bullet travel. If there are reamer marks left inside the barrel on the tops of the lands they will be perpendicular to the bullet travel and tend to foul.
Along with the above, it is also imperative that the barrel is chambered, threaded and fit to the action, and crowned by a competent gunsmith. A poor fitting and chambering job can force the best barrel to shoot under its potential. I've also seen the throat area of barrels polished with horizontal marks left from a chamber polishing that got too deep. It is unnecessary to polish a chamber beyond the shoulder. The lack of a shoulder makes it easier to get too deep with rimfire chambers.
One of the most important pieces to the puzzle is a straight and uniform throat that is concentric to the bore. The bullet must get started into the rifling straight. If it doesn't; it will become somewhat deformed and will not be centered in the barrel. Upon exiting the muzzle it becomes free to rotate around its new center-of-gravity, departing from the centerline of the barrel. In effect it will make a corkscrew-type path around the barrel centerline.
