Today I saw a Youtube video demonstrating how to align a rifle scope by using a flashlight shining through its objective to project the reticle onto a wall. After watching it, I saw a that there was another video on doing a tall target test (shooting at the range) to test whether a scope's reticle is aligned with its turrets. This got me to thinking. With your rifle set up to project its reticle on the wall, and accurately leveled with an accurate level on top of the scope's vertical turret, or its cap, the projected reticle could be compared to a plumb line so see if they were perfectly parallel. If they were not, you would be changing windage slightly when making an elevation adjustment. If any of your try this, please post your results. What we are trying to do is detect a manufacturing defect, not do an adjustment.
