Teehee, I was thinking the exact same thing.
:withAaron: I saw the episode of Mythbusters. It's kinda like the penny-drop one. If you fired a bullet into the air, and gravity pulls it back down, it just doesnt have enough mass to cause any major injury.

It pretty much means what is 'in the air'

They were close together... shhh.
I should have figured that Mythbusters would solve a mystery like this.

And for the bullet to escape into space, would need to go close to 11 km/s for a good distance. (It's more complex than this, but thats a the escape velocity for earth). Though it would be odd to have bullets flying through space...I think?

So what you're saying is that those crazy rednecks and those gangsta gangbangers who are constantly shooting their guns in the air are potentially saving us from an alien invasion?! :O Amazing.

Despite the gauge of the shot, you're only looking at a small order of magnitude difference between different sized shots. The shape is more important I would think, since that can change air flow more than a small change in size. (Though, I dont imagine it would change it TOO much on that scale) So I imagine that number is pretty standard.

Now I didn't get hit by a bullet, per se, I was hit with a small scatter of shot from a shotgun shell. It hurt all the same...
Why doesn't it kill you? Because it's no longer under the same velocity from the gun; it lost that velocity when fighting gravity. Due to gravity, it will reach a steady pace (once again, the larger, the faster) and keep that pace until it hits the center of gravity. AKA, the earth. The speed will be relative 9.8 Meters/sec squared. Not that fast, when you figure out how fast the bullet is traveling upon exiting the barrel.

So if you fired a bullet straight up; the wind resistance would counter the speed greatly; turning a lethal shot into a potential bruise!
