I've long heard this old chesnut regarding the relative (in)effectiveness of .22 LR against goblins: that a shot from a .22 pistol is effectively the same as stabbing someone with an icepick.
I've always thought of it as just a good analogy. No one would really agree that an ice pick is that great of a weapon, but it could certainly function in a pinch, it just wouldn't really stop an attacker who was the slightest bit determined. And if you put it in the whole Ears Eyes Nose Throat area, it could be rather effective.
Is there however any truth to this? Has some whacko with too much spare time and a block of gelatin ever tried to prove or disprove this? It came up the other time with some people swearing it was literally true. I argued that the ice pick was probably actually more damaging most of the time.
I'm not saying we should all rush out and buy .22s for self defense or that if the only thing available is a 22/45 you should use your car keys instead, I'm just wondering if anyone's been crazy enough to try this.
Slightly off topic, I have met a man who was shot twice with .22 LR out of a rifle at close range, and it knocked the thunder out of him, but he easily survived it with no scarring or lasting effects. He liked to tell that story and show where the bullets entered him, and they were right at COM. The ice pick as analogy seems about right to me.
