Buddy of mine has a Tasco 6 - 24 varmint scope with a mil dot reticle. We know that each dot is 3.6 inches @ 100 yards but he is under the impression that as the power setting changes so does the value of the dot. In other words, at what power is the first dot 3.6 inches at 100 yards. Obviously I don't know but I would think it would be consistant and not change throughout the power range of the scope. Anybody got an idea?
