I got to shoot a buddy's Thompson SMG today. I have shot it before, but it has been a long time ago. These things are really a lot of fun to shoot. I shot an MP-5 not too long ago and although it was fun, the Tommy Gun really is a lot more fun. It is way more fun than shooting an M-4 on rock and roll. I'm pretty sure that my buddy's gun is an M1A1. It was pretty easy to keep the shots on a man sized target at 75 yards when firing short bursts of 2 to 3 shots. Another thing is that his gun feeds and shoots about any kind of ammo, from target lead swc reloads to factory ball without a hitch. I supplied a box of my reloads. I shot half the box and my buddy shot the other half and kept the brass.
