I'm currently using it on a 556 gas gun and assuming I we're considering the same numbers in the reticle (0.5 mil down from x-axis/cross hair) the first number is 1 mil right/left of vertical.
The "1" wouldnt get into your field of view/overlap a target unless you were holding 1 mil windage at .5 elevation hold
In my neck of the woods that would be a highly unlikely situation and would be a freight train of a full wind value to have to hold.
The numbers ABOVE the x-axis, specifically the "1" works out to be a good reference for shooting movers if I hold the bottom edge of the "1" at the "head/neck" of the mover between 100-200 and gives me good results.
