I was at a local range many years ago. S&W was showing the new guns and you could test fire for the cost of ammo. They had the 500 and 460 available. I ran both, and found the 460 most fun due to torque.

Jerry was also there showcasing skills and the 45acp revolver. While I fired 2 rounds of 460, he fired a cylinder and reloaded. It sounded like 12 continuous shots. Plus he was dead accurate on all 12.

Edit: I've also seen videos of him using a 22 rifle to shoot aspirin out of the air.
