Q: What makes an Accurate Barrel?
A: An accurate barrel should possess several characteristics if it is going to be a "tack-driver". These include the concentricity of the bore, uniformity of the rifling geometry, twist rate, and quality of the internal bore surface. 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 surface finish of the barrel is poor then the barrel lacks the end-to-end uniformity required to shoot well. A rough finish will also foul badly, causing accuracy problems. The direction of the bore surface finish is very important too with the correct finish being 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. This is why the extra money spent on a hand lapped match grade barrel is one of the best investments you can make in a rifle. Also, hand lapping the bore in a factory barrel can also aid in accuracy as well make the factory barrel easier to clean.
