of a falling bullet, aprox. 150 fps. (Shouldn't penetrate the skin much less the skull.) Red Rider BB gun, around 240 fps.
That said, the gun would need to be fired directly up. Unlikely in such a stressful situation.
I'm not sure what to take away from this story. Just thought I'd throw a little science into the mix.
And Jberry too. That was an interesting, thought provoking discussion that I'm am glad to have read. All too often lately, debates on this subject devolve into poo slinging contests.
As for my 2 cents. I grew up pretty rural and learned to shoot around 10 years. Gun fire in my neighborhood is a near daily event that doesn't turn a head. Most of my gun owning friends are pretty NRAish. But I don't see any of them thinking open carry of a fire arm in a potentially victim heavy locale is a good idea. I understand they have the right. But people also have the right to feel fairly safe in their day to day doings. (Especially when their children are present.) So yes I'm getting splinters in my ass straddling this particular fence.
