Montana is the same. Also, Montana does not have a special black powder or muzzleloader season, but we do have some areas where centerfire rifles are not allowed but BP rifles, shotguns or straight walled pistols are...but the BP rifles are limited to some of the same rules as fritz posted Idaho has, as are our archery regulations.
