If you knew most of the Police and Game Wardens around here, you would totally understand why I would think they would snatch me up for using one of those things. Most of them couldn't find their butts with a map and don't know diddly about firearms. They would see, Brass Case, rifled barrel, BULLET not a SLUG (which most 12 gauge slugs are now anyway), and say "You got yourself a rifle here boy, time to go see tha judge". Now granted, as you said, it would be EASILY thrown out but who want's to deal with that mess? Firearms season is short enough here without having to lose a day because of stupidity.
