I am currently in the midst of setting up a Savage 10 FCP Mcmillan .308win. I have settled on a Leupold Mark4 ER/T 6.5-20X50 FFP. Now I am a little bit lost on the rings and bases. I plan on using a EWG 20 MOA 1 piece base for shooting at 200-600m on average, but may take it out to 1000 if the occasion arrises. As for rings, I am pretty much set on Leupold mark4 rings, but I cannot figure out what height ring I want. I was thinking a High ring, but would the 20MOA base throw that off? Sorry for my first post on this forum being a question that has been asked a billion times, but I searched and couldn't find an answer that was satisfactory to me. I tried the ring height calculator app and was a little bit confused. I'm just looking for some first hand info. Thank you
