Prohibit discharge of firearms under certain conditions on Class 2 waters

This bill prohibits discharging firearms within 500 yards of inhabited dwellings or outbuildings on Class 2 waterways in Montana, directly affecting recreational users of these waterways. The legislation amends existing Montana Code Annotated provisions to clarify that public recreational rights on Class 2 waters do not include firearm discharge near residential properties, with temporary absences of residents not considered uninhabited. The bill also maintains restrictions on other activities like big game hunting and overnight camping on Class 2 waters without landowner permission, while allowing the state commission to adopt additional rules for public safety and property protection.
