As I had mentioned in a previous post, the new reproduction scope and a SARCO mount shifted the windage too far to the left beyond the capability of the widgage adjustment to compensate based on use of an optical sight collimator.

I had time today to dig out additional reproduction scope mounts and did some comparison measurements of the thickness of the mount front pad as has been suggested.

My problem mount dimension 0.4885 inches

additional mount dimensions--all reproduction:

0.537
0.538
0.540
0.537
0.539
0.538

A factory mount measures 0.501. I was too lazy to pull down additional factory rifles/mounts.


I fitted the scope to the 0.540 mount and brought everything into reasonable alignment according to the optical sight collimator. At least I now have some windage travel available for final sighting in, if I ever get around to it.

It seems to me that if your interest is more in shooting than collecting, the repro mount with a Weaver scope would be more forgiving.
