I have it set to 20,30, 40 yd. If you have 5 pins, add 50 and 60yd. I also use a ballistic calculator and know how much hold over for 25, 35, 45, 55, and possibly 70.
huh? Not really. You let your rear aperture covers the the ring outline of the front sight. Then each pin corresponds to a given distance zero. The key is that the aperture outline overlaps exactly the outline of front sight ring, (the ring where all sight pins are anchored on).
