Re: more scope adjustment?
Yes or a canted base. Burris Signature Rings can give you 20 MOA or 80? clicks. (4 clicks/inch)
Some of the various manufacturers make 20MOA bases, Badger and Farrel and Leupold? I think make some. There are more I'm sure.
If you wanted, you could use a 20 MOA base and the Signature Rings and get 30 MOA to use up 120 of the 180 clicks you 'lost.' That might just allow you to shoot to 1500+ yards with the right bullet.
