rick,
It won't, but it helps determine if the problem is in the scope, mounts or rifle.
Often scopes get blamed for running out of adjustment, when the most common problem these days is in the mounts (or how it was mounted), and sometimes in the rifle itself.
Yes, sometimes there is a little wiggle room in the mounts themselves. A lot of guys think you can just throw a set on and screw everything together and you are fine. Simple truth of the matter is it doesnt always work that way. Theres a reason they make alignment tools. Mounts should be mounted perfectly perpendicular to the axis of the bore, that way the axis of the scope tube will center itself on the axis of the bore. When you do this, it requires very little windage adjustment on the scope. Ive actually seen some huge poi discrepancies on rifles that had scopes not running perfectly down the centerline axis of the bore. When sighted in at 100 yards, their horizontal poi changed by more than 12 inches at 400 yards. When shooting short distances, its not much of a concern, but when stretching it out, it could cost you a game animal. All the more reason to center your crosshairs optically and then adjust the mounting system for true center.
