I tried to shoot at 1 mile this am. I phone called for 65 moa. I dialed up to 60 and that was all the nightforce had in it. It already has a 20 moa rail that came on the gun. What can I do to get just 5-10 more moa out of it? Would taller rings help? If I put a 40 moa base then I will have to get rid of the big pictanni rail deal.
