There was a magazine article 2 or 3 years ago, they were testing scopes with the 460, took one to a range, tried to get anyone to shoot it, maybe hot handloads. They broke their lead sled, then a scope mount came off, sheared the screws right off. Sounds incredible but there were pictures. There is also a youtube somewhere with guys shooting a 600 Tyrannosaurus, indoors, looked like a ballistics lab or something. A few dropped the rifle, one got bowled over so bad he broke the glass door behind him. Some may not have been experienced shooters. I've had 458s with no break, really not that bad, but the most foot pounds I ever threw was with a Ruger Magnum in 416 Rigby, loaded to the fare-the-well, I'm afraid. Weight is everything and the heavy Ruger felt like a shotgun, just a push. The gun that hurt me the most was a light Styer in 308 and I think the problem there was a too-squishy recoil pad that would bottom out while the rifle was still moving pretty fast.
