What is confusing about running a small chart on the stock? Range, aim with the proper dot (gapping as required) and it works. I've shot a lot of prairie dogs and some coyotes with the LR dots, Varmint Hunter and B&C reticules and have no issues out to 500 yds or so. Dead simple once you build the chart based off shooting the load you use. Beyond 500 dialing is the way to go. And varmints are a bunch smaller than big game, which I hunt with a bow & arrow.
