I have heard that the finish on some of the Weavers allow it to "move" in the scope rings. Have you been witness to this or have you also heard of it ?
I had a scope moving on my 30-30, so I bedded everything with a little JB weld, Bed the base to the barrel and bed the scope to the rings. Removing it has not be a problem with a little heat and perhaps a wire wheel on a dremal. They haven't moved since then. If you have a matte surface, wipe it with a little gun oil to aid in release later. The indexing action from the rough surface will keep it from moving.
