JJS: The only unit I've had scope travel with is a 257 Weatherby with a B & L Elite 6-24X, a fairly long and heavy scope. Tigtened rings to no avail. Shimmed inside with aluminum foil to no avail. Put masking tape around scope adjacent to rings, put a light bead of silicon seal around scope, screwed together, removed tape to take off seal leakage, and it has not moved since. With just the bare rings and shims, the movement was actually shearing the exterior finish off the scope. I have pulled another scope that I gave identical treatment to, and it was no problem getting things apart. Good luck. 1Minute
