My ALMOST worse experience:
I was doing range officer duty at the local club. A member showed up with a new .458 Lott which he was very proud of. He offered to let me shoot it after he had it "dialed in." I watched him shoot it at the bench - at each shot his shoulder looked as if it was trying to jump backward right out of it's socket and he'd practically fall out of the stool. You could just about hear his teeth rattle inside his head. He'd compose himself and get settled back into place after each shot. To his credit, he touched off about 8 or 9 rounds. After that he turned to me to give me a chance to shoot it. I said, "No, thanks." My IQ is low enough to risk having my brains scrambled any more than they already are.
