For those of you who are lucky enough to own Automatic Weapons, how often do you shoot them and how many rounds do you shoot? For those whose belong to a place like Frontsight that has Auto weapons classes and spend 4 day weekend shooting 1600 rounds from an Uzi or M-16, how often do you do it? 1600 rounds of .223 or 9mm is expensive. Other full Auto ammo even more. Plus you can clear out a small stockpile in one outing. So how often do you throw that much lead and money downrange? Are Full Autos worth it to own?
