[QUOTE="bruce_ventura, post: 700201, member: 34084"] On a decent quality scope, the elevation adjustment should be reliable out to a click or two short of the limit stop. This is a micrometer device, after all. It should be linear from one limit to the other. On low quality scopes, the reticle may stop moving before the limit is reached. Keep in mind that your standard base may not be parallel to the bore. The barrel could be bent, the barrel could be installed crooked in the receiver, or the receiver or mounting rail could have other dimensional variations that could affect the alignment of the rail. Expect up to 3 mils of misalignment in any direction on a production rifle. Some are even worse. FYI, you could also use Burris Signature rings to add up to 2.5 mils (30 mm rings) or 5 mils (1" rings) of adjustment. Signature rings will allow you to correct mount misalignment errors in any direction. [/QUOTE]
