In the parlance of his time, he would probably have said it would make a dog laugh. Why? Well, an important part of his research produced Newton's Laws of Motion, which say among other things that objects tend to stay where they are unless something moves them . . . . . . And once something is moving, it keeps going until something stops or slows it down. Have you seen the YouTubes of scopes flexing under recoil? If not, search those words and you soon will. One by ‘Bob is the Oil Guy’ shows the scope on a big tactical rifle dipping at the objective and the back of its picatinny rail lifting. These things happen not just once but two or three times from one shot. We can only see this process because the rifle is so straight and heavy that it does not rise off the bench. Another video shows that scopes flex even on smaller calibres like the 6.5 Creedmore. Imagine what the erector tube is doing inside those scopes. It’s not held by solid, steel scope rings but by a gimbal or ball-joint at the back and usually just a flat spring or two at the front. A stronger spring might just hold it in place on smaller calibres but on big ones the erector tube will sti...
