My 2 cents - a EGW 0 base with Burris XTR signature rings. The inserts supplied with the rings will give you up to 40 moa just by using inserts and your not going to find a scope that can use that much unless its a SWFA. If your scope will let you mount the rings 4.75 center to center the MOA will track. With 20 moa bases and other rings its a crap shoot. Plus your not going to get ring marks on a new high dollar scope.
