Thanks for all the info, really appreciate it!. I figured I would find out for sure if I was going to get in trouble, and brought it to the police station in the town I was going to fire it in. Cop asked me what time I was going to shoot it, as he wanted to check it out himself! So, a pound of pyrodex and a ton of lead later, I believe I have made the coolest thing ever! Ever see what a 1" diameter lead slug will do to almost anything? Brought a bunch of milk jugs full of water, trash can full of water, computer monitors, microwave, and other assorted stuff to be blown up. The trash can was the best, as it shot a huge stream of water about 50 feet up. I still haven't got any pics yet, but I will later today.
