Comment: So the headline states that he used a shotgun (which won't detonate an exploding target) and then states that he had a semi auto rifle, so which is it? Also, I think it was a typo, as there's no such thing as a 25 round exploding target. If indeed it was a 25 pound charge then it would have demolished his entire house and possibly part of his neighbors. Either way, a very foolish act.
