I mounted my scope on a Savage 6.5 long range with a 20 moa rail also so I can try to get to a 1000 yd with hand loads. I'm not having any issues with elevation just windage due to not being able to go far enough left. I bought the package that came with rings so I'm wondering if that might be the issue. I've got the same rifle in 300 win mag with different rings and scope and had no issues getting it in within 10 shots or less.
