Video above is a good reason, all by itself, to go with larger scope tube scopes on the heavy recoiling rifles. And to not have any cantilevered rails. At least part of the scope's flex was due to the rail bending because there was no screw at the rear of the rail and the rail itself was not sufficiently rigid.
It occurs to me that if the recoil lug of the rings were a tight fit to the slot in the rail that perhaps more than two rings wouldn't be needed? This assumes lapped or bedded rings that won't allow the scope to move within them.
IF that is true, then we're going to be seeing various bedding techniques for the rings to the rail? E.G. bias the front ring to the front of it's slot and fill in the gap with bedding compound, and bias the rear ring to the rear of it's slot and fill that gap with bedding compound too? Or maybe we'll be using red locktite to adhere some shim stock to the side of each slot to reduce the gap to zero? Maybe we can get one or more of the premier ring mfg's to start offering rings with an over-sized lug so that they can be fit to the exact slot. Then the question would be, do we thin the lug (can see a camp arguing that makes it 'weaker' - never mind that it's already wider than the spec) or do we widen the slot to fit the oversized lug (another camp arguing against because it removes the finish and/or makes it harder to fit the next set of rings). Along about then someone will make rings with double, opposing tapered lugs that fit in one slot. Tightening the mounting screws or nuts will cause the lug to "widen" to the point of completely filling the slots in the rails and sending all of the previous band-aids into the rubbish bin.
At least, that is what my crystal ball is showing me this morning......
