Makes sense to me,! That's what I did. I had a 40moa rail on my 338 Edge, and I have a Leupold MK4 with a total of 70 moa. Since half is 35, and I still want a 100yd zero, I sold it and got a 15 moa rail. When I get good enough past 600 yards, then I will worry about putting a 30 moa rail on it to maximize my distance!
