I'm sure they wouldn't like that very much either.. Give em a call, The ATF are the nicest people to talk to on the phone,.. I've called them up with some crazy/stupid questions and they were always happy to help me, they even mailed me some stuff, class 3 forms and a little booklet of the identification of a 3rd class weapon.. It was described as being able to shoot more than 1 bullet without.. well... not to sure about the specifics, but rule of thumb would be 1 bullet for every 1 pull of the trigger, or else start listening to that DMX song ATF
