CG,
On my 1500 Varmint, I used Leupold two piece bases. The gun is not a kicker (22-250) so a "turn in" rear mount was not a concern. Two, I used Burris Signature rings because of their synthetic inserts, which help compensate for minor misalignment, and are easier on the scopes finish. Last, I like the looks of the Leupold bases. So far so good.
