My advise first of all is a brake. My RUM is a thousand times more pleasant to shoot after I had the brake put on. (Wild West Guns, by the way.) I handload really hot and I have no fear of getting scoped. (My groups shrunk, by the way - just felt more confident.)
As far as scopes, I have a Nightforce NXS 5.5-22x56 with an NPR-2 reticle. It is huge, heavy and expensive, but once you look through it, and shoot at 500+ yards, you will never want to look through anything else again. It is unbelieveable.
