Assuming the base is machined correctly to be true 20MOA, and the final mounting height of your scope is not higher than with your old rig, you should be fine. Even if you changed your mind and zeroed at 100 yards, the difference can't be more than 2 MOA. It'ill be close, but the added up travel will maximize the capability of your rig to the limit.
Best of luck.
