I mounted an old 3-9X Marlin scope on my new Ruger M77, with its integral receiver mount and front and rear rings. This isn't the final setup as I'm going to be using a Leu 2-7 x 33. It was just to fire-form some new .338 cases to set sizing and expansion plug die for shoulder bump.
This scope is old, but works fine. I borrowed it off my son's Marlin 30-30 as he's now using a Skinner. However, on the Ruger, the elevation adjustment taps out with the scope shooting really low.
I only now noticed the Ruger ring top and base are a matched pair? I know the higher ring goes at rear and the lower up front (I have the factory "medium" setup, with the No. 5 rear and No. 4 front ring), but now I'm wondering if I got the tops and bases mixed up? If that's the case, how do you know which top goes with which base?
I am likely looking for a new base to mount the rings anyway - my existing Leu Freedom 2-7 x 33 1" scope is too short for the existing receiver mount. So will have to look for an after-market adaptation mount or extension rings that will fit the Ruger. But that's another issue.
