Re: Can I get a lesson on the H 27 Reticle?
It's a mil-scale reticle where the parallel lines are separated by 1 mil (milliradian). You don't dial your elevation and windage; instead, you hold for elevation and windage using the grid pattern to guide your eye. The rifle is first zeroed at the origin point. There are ballistic calculators that will give you elevation and windage holds in mils, so you just hold at that point in the Horus grid. Pretty straightforward, it's the shooter's version of hands-free dialing.
