Not a gun story, but almost...
Young and dumb(er): Took a .22 cal blank (for Hilti nail drivers and such) and put it in a hole in a piece of metal machinery, and hit the primer end with a Phillips screwdriver and a hammer. Either a piece of the case or the escaping gas ripped a gash in my forearm that took 6-8 stitches and a lot of paperwork (this being on the jobsite) to get over.
Lesson learned.
