A cheaper, more accurate and easier way to measure scope adjustments is to mount a yardstick 100 (or 50) yards downrange at right angles to your line of sight. Clamp the scope in something solid aimed at the yardstick at one end with a reticule line on the yardstick. Move the adjustment for the other reticule line 20 major units, MOA or IPHY if so spec'd. See how many inches it moves on the yardstick. Remember your grade school math to figure out how much each major unit of adjustment moves the reticule.

I've clamped a scope on the vise on my basement shop's workbench and put a mirror about 50 feet away on the far wall of the family room to reflect the ruler on the workbench; a total distance of 100 some feet. Was easy to check my old Weaver T16 and T10 target scopes' movement per major adjustment.
