Colby,
With a high BC bullet in the Grendel velocity range you're going to need up to 15 Mils of elevation to get to 1K yds.
Your scope will be roughly half up and down, so at 0 cant you already have 15.5 Mils of available elevation. Add to that another 6 Mils for a 20MOA base (3.438 MOA = 1 Mil) and you have 21 Mils of dial-up elevation. A 20MOA base is more than enough.
