I heard a story about a young boy who was killed when he threw a .22 lr round down on the cement at his feet. Since it was rim fire, it went off when it hit the cement at the correct angle. The bullet supposedly hit an artery in his inner thigh.
I know you have disproved the lethality of a .22 without something behind it. This sounded plausible because the cement may keep the brass from absorbing half the energy.
If a .22 lr doesn't quite work, you could try a .17 hmr or .22 mag.

The science was explained when they dropped ammunition into a camp fire.
Basically physics takes over.
When you set off a round of ammunition outside the chamber of a gun an equal force is applied to both the bullet and the casing. But since the casing is considerably lighter than the bullet it is that that gets moved.
Even a .50 calibre BMG bullet will, when detonated outside of a gun, move about half an inch with the casing being thrown around a foot or so with enough force to cause minor injury. It is not entirely beyond probability that the injury *might* be enough to be fatal if it is deep enough to hit an artery. But it is highly improbable.

Cyber, I think what he's saying (or asking) is that this is a different setup. In their other tests, there was nothing behind the casing to keep it in place. In this situation, the ground might give an instant of resistance, giving the bullet more "oomph".
Personally, I don't think it would be enough to matter, but I don't know guns or ammo.

I'd guess it's extremely unlikely, but possible.
Seems like a pretty stupid thing to be doing regardless.

Very stupid.
I had a friend as a kid who had the brilliant idea to tape a marble to the end of a shotgun shell, toss it up and see what would happen. I don't think he was ever stupid enough to actually give it a try, though.

Question one, will Rim-fire rounds fire if thrown at the ground.
And what force would be required?... casual toss, or full blown baseball pitch type force?... or more?...
I have no idea... its not something I have ever thought abut trying?... as in, I aint THAT stupid......
I have dropped a couple of rounds whilst loading a clip, but never with any force or height, and I always did that over something soft anyway in case I dropped a couple.....
Question two, with the ground behind them preventing reaction, will all the energy then be forced "Upward" providing a possible lethal projectile.
I have to say physics says "Plausible" on that.

I am doubting the first part of the premise - and THAT should be easy enough to test. simply extract the bullet from a .22 rimfire cartridge, crimp it into a fired cartridge, and then throw it at the ground to see if you can put enough force on it to dent the primer.
it might be worthwhile to make a blowgun with a graduated clear tube to guide it at an optimum angle, and provide a frame of reference for the high speed camera to determine what velocity is required to make enough of a dent to be deemed sufficient to trigger the priming charge.

Remember the episode where they had tested the "redneck fuse" for cars? They figured that it might be fatal but the chances are very low.

Darwin Award nominees and honorable mentions are pretty much the MythBusters' bread and butter. At least it was for the first couple of years. If they were to reject a myth on grounds of its sheer stupidity, the show would have never lasted 10+ years ;D |

Just the probabilities and the poor judgment of the action. Even if perfectly safe, it seems like it would foster an unsafe attitude regarding the handling of guns and ammunition. |
