Right now I am using SS10x42, Millet 2 piece base and Millet angle lock high 30mm rings. My 100 yars zero is at 75 MOA on the scope. Today I ordered a SS10x42HD. I am thinking of using a 20MOA base.Would that just bring my zero at 100 yards to 55 MOA.I also know the new scope is MIL & not in MOA. My rings are also a little high. I will be getting MED. rings
