A recommendation would depend on all that you want to do with it.
Regarding recoil, It really isn't that much on a 300 RUM.
Any of the medium to high price range scopes from one of the better manufacturers would hold up to the recoil.
Magnificaion, turrets, retical and objective lens size would depend on what you want to do with it.
Good luck with your search
