I recently installed a set of dual dovetail mounts on a Rem 700 270 WSM. The front ring twisted in with fairly firm resistance. The rear ring twisted in with surprisingly little resistance. When I took the clamp off (more on that later) I could twist the ring by hand. How loose can these be and still be considered correct? The ring doesn't wiggle, but it can't have near the spring tension the front ring is under. I used a Bessey K-body clamp to twist the rings in. I thought it worked pretty well. Anyone tried the clamp and what should I do about the rings? Burris DD's and sig rings.
