I'm helping a fellow that picked up a #3 not long ago install a scope. The two piece Ruger mounts were purchased from shopruger.com and installed. Then two Ruger rings I had in my stash were utilized. They looked like a perfect match due to the front ring's base was taller than the one for the rear. Picture for details:
Upon firing the bullet hit approximately 6 feet low. The scope elevation was cranked up to the max and the next put a divot into the dirt about 2 feet low. I suppose a shorter front ring base could be utilized, but not having shimmed a ring, or base mount, before is 24" plausible? In reality it would need to be even more than 2 feet to recalibrate the scope closer to zero on the elevation setting.
Thanks for any suggestions you offer.
