Chris,
I would look for some of those self-sticking pads (thin, though) that will go under the clamps and over scope tube. You want to grip the tube but not crush it. That scope sounds like a real "cannon", and yes, the momentum of the recoil will definately cause that beast to move. I thought I had my new scope nailed down too and it did the very same thing! Sometimes the scope box has those pads included in the package.
