ok, then you sit on top that receiver and tell me what you feel.
"Think about the most extreme situation. The gun is put up against a solid brick wall. The stock is strong enough not to give under the extreme recoil. The scope sits perfectly still on top of the rifle. NO recoil at all is felt by the scope." Scenario is impossible. Where does the recoil go then? Compression of the stock? If the stock comresses, the scope moves.
I think your scenario and the one above are erroneous over simplifications of a complex situation so far as energy distribution during recoil but do not claim to be able to offer definitive proofto the contrary. It isn't how far you fall, it's how fast you stop.
And further, let's pose this question to Twanger on HA - he ISa physicist.
WHUT?
