I am mounting a scope on my .22 with "tip off" mounts. The mounts do not go all of the way down in the grooved receiver. The middle of them hits on the top of the rounded receiver. When you tighten the mount, it grabs the groove but not on the bottom. I am afraid the scope will not be on there securely. It this the way they mount? I am afraid that the point of impact will change or worse, the scope could come off. I am thinking of having the mount radiused so it will fit the top of the receiver. Am I over the top on this? These are Talley rings.
