If anyone is really into survivalism, this would fill a meat gathering role. No caps or primers to worry about. One could stock up on lead and mold their own. Those little solar battery charging units can keep you charged. And if worse comes to worse, you can make your own BP! Hey, if Captain Kirk can do it while being chased by a big lizard, so can you! That is of course for you guys who are old enough to remember that episode.
