That certainly is a cool video , from the few 50's I've shot the recoild wasen't any worse than a 12ga shotgun and only oone was that bad the rest kicked about like a 30-06 maybe a bit more of a push , that gun appears to have some pretty substancial recoil.
What actualy causes the scopes on 50's to fail is called "dual stage recoil" , the gun starts in motion rearward and as the bullet comes clear of the muzzel and the massize brake takes effect it stops most of the rearward travel and in some cases drages the gun back forward.. The scopeis generaly only insulated against recoil from one direction and this two way effect wrecks them
I have killed more scope with a RWS model 48 pellet rifle than I've ever heard of on ANY other gun , this is also due to the dual stage recoil , one in the rear direction and again in the opposite direction when the spring slamms home , it'll beat the guts out of some of the best .
