I never have but I was watching a friend of mine shoot my Parker Hale Mauser in 7mm Rem Mag last year. The scope cut him pretty good over his right eye. A little more and he would have needed sutures. Well, he immediately thought the scope was set too far back. I had been closely watching him shoot and I didn't think that was the problem.
So I sat at the bench and touched off a round. No problem. The scope didn't come close to touching me.
This is what happened to him. As the rifle recoiled into his shoulder-forcing it back, his cheek weld was lost and his face was still in the initial firing position when the scope got there. In other words, he was holding his neck too loose. As a result, his head was not moving to the rear with the recoil.
I told him what he was doing and to hold his neck stiff enough to maintain his cheek weld. He did so, and his head moved back with the recoil. We didn't adjust the scope and he shot the rifle for the rest of deer season without further trouble.
