Decided to go with the medium rings. It looks good and feels good when I throw up the rifle.
Fortunately the eye relief is good as there's no extra room on the barrel with the rings and bases mounted as intended. Almost up against each bell. I could move it closer to the stock end by reversing the mounts, but then the mount would overhang the ejection port area....or machine off the front (then rear) groove.
The Warne horizontal split rings form a nice transition between the 60+ year old rifle and the newish Leupold.
Can't find my torque screwdriver, but I did loctite the bases. Left the rest without.
