I saw these 12ga bean bag shells on Cheaper Than Dirt and thought they might be usefull for indoors protection. Has anyone tried these or trained in law enforcement or crowd control with these rounds. Haven't got out to try them yet but wondered if they might be ok for first and second load in an indoor pump 12ga. They do say that close head or chest shot could be fatal but my thoughts were not likely to penetrate walls. I would like to hear from someone who has some experience with these and not just normal gunblog conjecture. Thanks.
