I tried to sight in my M1 last night, and ran into a problem. The first time I zeroed it, I discovered that after a couple dozen rounds, the scope had started to rotate inside the rings. I figured it just wasn't tightened down enough (I'm a novice when it comes to mounting scopes). So I loosened it, got it back in the proper orientation, and tightened it down as tight as I could get it with a T-handle hex wrench. I re-zeroed it (and it zeroed great, with a nice tight group). Shot another clip, and found the scope doing exactly the same thing again. It ended up canted about 20 degrees counterclockwise.
Any ideas on how to cure this? The bolts are as tight as when I mounted them, but the scope is still turning in the rings. It's a Burris 2-7 pistol scope and (IIRC) Millett rings.
