Have you considered rings? Burris makes XTR signature rings that go to 40 MOA using inserts. I have them on my savage 338 FCP. Working good so far for me. I have a 34mm scope. The Burris only comes in 1 inch or 1.5 inch height. Measured wrong and ordered the 1.5 inch. Had to order the 1 inch and trying to sell the other.
