Another popular shoot...
There is also a group in Oklahoma that has a big shoot like that. It is a group of Firearms dealers, etc. that get together once a year. It is called O.F.A.S.T.S. (Oklahoma Full Auto Shoot And Trade Show). I had a relative that had a booth. I saw everything from full auto pistols to vintage military weapons to M2's to miniguns. One guy did a demo shoot of an inert projectile 20mm Carl Gustav.
