Interesting video over at ENDO about the lethality of .22 lr at long distance. They use the breaking of a 1/2 inch pine board standard for judging lethality. It takes 59 ft/lbs to pierce the board. IMHO, I dont really see this as an all encompassing test of lethality, but it certainly is a good measure.
The .22 short was also impressive.
Also, I’ve said it before and I’ll say it again… .22s dont kill people. Women with .22s who are about to get raped do!
