I read the proposed changes to Montana law that would make suppressed rifles legal in some instances. So, I'm not disputing that the Montana state legislature might have changed the law to make it legal to use suppressed rifles on non-game animals and coyotes. However, I'd advise anyone who intends on using a suppressor in Montana to contact MT Game & Fish and if they say it is legal to use a suppressed rifle on non-game animals and coyotes, have them put that in writing, sign it, and send it to you. What some person said over the phone may not be cut in stone--BE CAREFUL.
