After much consideration, and numerous hours studying all the great posts, I've decided the .308 will be my first long-range cartridge. I'm a M700 fan, and have decided to get the LTR in .308. I already have a Leupold VX-III 4.5x14-50mm scope (1 inch tube) that I'd like to mount on it for now, but someday I'd like to get the Nightforce 3.5x15-50mm with 30mm tube. Will the Badger scope rail with 20MOA cant and medium rings (0.885" high) work for both these scopes? Of course I'd need to get the scope ring reducers for the Leupold. My concern is with the Leupold and its 1" tube. Will the 20MOA cant cause problems at short range (under 100 yds)? Thanks for the Advice.
