I've been interested in expanding my range with my M1A. As such, I've been looking around for a new rifle range supporting out to at least 600 yards (stretch goal). Obviously, this means an outdoor range. I was pleased to discover many possibilities in my area until I learned that many of them banned FMJ. The reasons I was given ranged from FMJ tearing up their backstops to hitting rocks, sparking and catching fire. Needless to say, I'm confused by this. Obviously, people can run their ranges however they want but banning FMJ on a long distance range seems odd. What am I missing here?
