CLEO signature is apparently going away soon, but I doubt our new Sheriff has any issues. Montana is very gun friendly. I've never had issues getting fingerprinted, and the former Sheriff had my forms signed in a couple of days.
You picked a great place, Bozeman is a great city and has a lot
of Vets, myself included. Just stay away from our sorry excuse for a VFW post in the Filling Station.
I have plenty of NFA forms if you need any and can walk you through the NFA process. Langley Munitions is who I went through for my Cyclone here in Bozeman. He's a good guy. Last I heard from him was a hacked spam email so I'm not sure if his contact information is still correct. He mainly does AAC stuff.
The Manhattan Wildlife Range is a great place to shoot, and everybody is NFA friendly. Worth the 15 minute drive out of town. Bozeman PD and the Gallatin Sheriff's Dept. are pretty good about NFA stuff and a few are on these forums. It's common to run into them at the range, and they're good people.
You might check out http://mtfi.org/
and see if they're interested in adding a tactical medical program to their courses. I don't think a standalone business would fare well, but if you piggy back off them you could still have a program. That's just my two cents.
We also have the best beer brewed in Montana
