Re: Where to zero?
MOA, I am guessing your target knobs are by Stoney Point. They are only registered for one revolution which I believe is 12 MOA on your scope. After one revolution, you are on your own for remembering where you are.
Not a good setup for LR shooting where adjustments can exceed one revolution. If you have the time, send the scope back to Leupold and have a target turrent installed on the elevation knob. These knobs are great! Have a vernier type scale and clearly marked increments. Very nice adjustment for visual and feel. I think it costs $45.
You can leave the Stoney point on the windage. You will never need more then one revolution for wind. At a few MOA of adjustment, it is too windy to shoot at game LR.
