Well that's a problem in Idaho... Modern inlines are not legal during ML season. You have to use a inline that uses caps (either #11 or Musket) for ignition and it has to have an open breech, with open sights which puts you back a generation or two in ML's. Basically it will be a plunger type action.
There is a rumor that Thompson Center is going to make and release a Pac Northwest inline this coming year - but so far I have just seen a few converstions about it.
