I'd doubt the bullet went too far.
Couple of years ago I was fooling around in the woods with my old Tec-9 with some friends. You know the Tec-9 drill - Rack, bang, bang, jam, curse, rack, bang, jam, curse again, rack, bang, jam...
Suffice to say about 40% of my ammo was getting mangled on the feed ramp and I didn't want to try to feed most of it again. So I didn't.
Cut to a few minutes later and I find that one of the dimmer members of the party has set up a round on top of a pyle a little ways away and is taking aim at the primer with his air rifle. "What the eff do you think you're doing?" I demand of him, "Even if you do hit that thing - which you won't, because I know your aim - the casing's probably going to hit you right between the eyes. So don't effing do it, I'm warning you."
Famous last words: "I know what I'm doing."
Couldn't talk him out of it, so I got 'round the opposite side of a rather beefy tree and put my earmuffs bacn on while he lets it fly. Miss, miss, bang! Stray piece of fragmented brass catches him in the left hand.
He wasn't hurt very badly at all. We picked the sliver of brass out with the pliers on my multi-tool and he bled for a couple of minutes and that was it. But it learned him real good, I'm sure.
The other end of this story (perhaps literally...) was that we shortly thereafter found the bullet from this round. It was lying in the dirt about five feet away from the pyle and its shiny copper jacket gave it away. I don't know how far it really went because the pyle was maybe three feet tall to begin with. But it didn't go far, and if the bullet had actually hit somebody it wouldn't have done a thing to 'em.
