They're not like military rifles, there's no set distance associated with each step. Would be hard to do given the variety of ammo out there. And windage is equally haphazard with the factory-supplied open sights. Adjust it for one load at one distance and learn how the bullet flies at other distances. Take a brass drift and mallet with you, decide what distance you want to sight in at and get your group centered up on the range. If you want to get a little more regular, get a Lyman, Redfield or Williams receiver sight with knobs and click stops. But I guarantee you that a deer just isn't going to stop and let you twiddle with knobs for the right range. Best to learn how your bullets drop at different ranges and aim off.I've searched, searched, and searched around and have yet to find a definitive answer on this. Has anyone done any research on this? What's the yardage these elevator sights are set at? Is it by 25 yards, or?
