I was taught in medic school, that the 22, is responsible for more firearm deaths than any other round, they tend to bounce around inside the body, and an otherwise non fatal wound, could be fatal because, there is no telling what it will hit after it enters the body. I would think that more people are shot by 22s than any other rd in the U.S., at least when the book was written. Before anyone says it, I know bullets don't kill people,... people kill people. This was 18 years ago, 9mm may be the most common now, I'm not really sure, times have changed, but it may still be the 22. As far as shot placement, I go to the range, at least once a week, and twice when it is warmer, the range is about 3 miles from the house, I can hear the shots when I'm outside. I hit what I'm aiming at, under the stress of a robbery, I can only hope I stay calm, and make em' count.
