Chucks in Southwest Montana? Who to contact?

[arthurj]

Hey guys I've got a trip planned with my father and brother to Ennis, Montana from august 13-20 to do some flyfishing. I would certainly love to shoot some chucks though, I just don't know the best way to get it set up. Anyone have any recommendations? Should I just look at some outfitters? I'm not looking for a mass slaughter, I just want to lob my 308 around.
