The two attached news reports are about subjects being shot in the head with .22 caliber rounds. In both the subject lived, in one the victim was shot several times and was still able to get to a gun in his nightstand. I would say .22 is not my first thought for self defense. http://www.khq.com/story/21664703/police-lolo-homeowner-shoots-visitor-in-the-head http://www.columbiabasinherald.com/news/article_cda1f2ca-8a78-11e2-b2f8-001a4bcf887a.html?mode=story Wanna kill these ads?
