The brake is what is destroying them. It produces a recoil curve like an airgun. ok please explain , I know air guns are hard on "normal" scopes because of their "backwards" recoil but a brake cuases this how ? Its a pull push effect like what the heavy spring does on a air rifle when it moves toward the muzzle compressing all that air . Most scopes are designed to handle a rearward recoil . I know a guy that has shot a 30-378 for many years in fact it is his only big game rifle , he does not have a brake on it . Last time I talked to him he had the same old VXIII 4/5-14x40 Ok got you, I was doing some reserch on this pretty much same answer. so seems to me a heavy scope would amplfiy the problem. I would imagine so if the innards were heavy as well

If you have the time watch this video...It is long but explains the reverse inertia. Same as the airguns exhibit! Here about the 15 minute mark https://www.youtube.com/watch?v=9fe4l_CAthI

The height of rings needed to some of the foreign made scopes with 50 mm objective lens added to these failures, the height of the center mass increases the shock factor, some will even notice creep in the scope over a string of shots.
Some of the aluminum pillar blocks molded into the stocks of the early 30-378's were not square or true to stock, this caused the screws to shoot loose and scopes to move, but milling the tops flat and truing up the recoil lugs solved all of the problems, even with the big Zeiss scopes.
