Weightlifter shot when he drops dumbbell on bullet (or so he says)

10. You're exactly right.

A rifle round or something else similarly high-powered might be dangerous, but a .22 is the weakest kind of round available: even when fired out of a gun it's very low on the danger scale.

Personally, rather than "somebody shot him and ran off," I suspect this is more likely a case that the guy was handling a gun unsafely, shot himself, and then made up a less-embarrassing story to tell the emergency room workers.
