Bah, I can't find a link - too many hits and no combos worked.
The story, IIRC, was that some guy buys a Desert Eagle 50 AE at the gun store or rents it. There is an indoor range. Dude goes to the lane and the gun is too much for him. He leaves the gun and tells the range employee that he can use up the box of ammo. The employee is found with two rounds fired. The analysis was that the first round recoil brought the gun back and he spasmodically fired one back into his head.
I don't think I dreamed it.
