OK, I can stand to be corrected however that practice seems to work for everyone else that I've worked with. It works best if you are in a bench rest position with the firearm supported and aiming at a white background or even a clear blue sky and adjust the focus very slowly. There should be a point where the reticle comes into clear and darker focus than at any other point. It is a very fine adjustment so take it easy and don't stare through the scope when doing it or the image will get burnt into your retina. Adjust, look away for a bit, then adjust and look away until you find the sweet spot.Sorry to correct you. I adjusted it all over the place and the results were the same.
