Take a yard stick to the range with ya and make sure it calibrates right and at what power.
Sorry, this is not meant as a slam or to flame you but what is your statement getting at! Splain Lucy! You can't change from Mils to MOA because of the focal plane or power setting. Your reticle is calibrated for one or the other.
Mils are Mils and Moa is Moa, they are totally different measurements, they aren't interchangeable and they don't change. 1 mil @ 100 yards is 3.6” and 1 MOA @ 100 yards is 1.047”. I don’t see any logic in your statement.
If you want to measure the accuracy of your mil-dots, make a cross on a target or a sheet of the paper that is exactly 3.6" from the center of the cross to the end of each vertical and horizontal mark. Put the target at exactly 100 yards and verify the accuracy of your mil-dots or hash marks. If your reticle is in the second focal plane, turn your power ring until the first mil-dots cover all four marks. Mark your power ring so in the future you'll know where to turn it to for ranging.
If your reticle is in the first focal plane, then verify the accuracy of the mil-dots or hash marks at all power ranges.
