I recently bought a 4-14x44 scope with a 30mm tube. It is going on a Remington model 700 with weaver style bases which clamp to the rail using a cross screw. This rifle has functioned very well over several years using a one inch scope, so the rifle isn't the problem. The factory rings that came with the scope are visibly out of concentricity with one another so I replaced them with a pair of Weavers. The scope prints about eight inches low and left at about 25 yards, obviously too much travel for the scope to handle with the knob adjustment. My question is what can I do to fix this? Has anyone had any experience with this problem with the rings? What is the proper procedure for mounting a scope like this? I'm not inexperienced in this area, but I may be overlooking something. Lastly how does one return a scope to its zero?
