And not to beat a dead horse here about this .22 ordeal, but I will anyway
I believe it was in Isreal the PDs there and the military decided they needed something that they could use for riots to "control" unruly crowds. They actually picked Ruger 10/22s with bull barrels from the factory. They put some good glass on them and was told that they were to shoot people below the knees with these "undeadly" little .22 rifles. They did and what they found was that these "tiny" "Undeadly" little rounds were killing more people than what they were wounding. They had to pull all the 10/22s from their invetory because of how deadly these things were, even just shooting people in the legs.
I also read a report a while back that was about some guys shooting frozen turkeys from 500 yards with bolt action .22 LRs. What they found was even though the turkey were frozen and they had wrapped them in denim and rain jackets they were still getting massive amounts of damage on the turkeys at that distance.
i stick by my guns that a .22 LR is not the first choice in my BOB, however if that is all I had at the time I would use it with no hesitation. Any firearm that goes boom can kill. A .22 short will kill with the right shot placement.
