Prohibit discharge of firearms under certain conditions on Class 2 waters

This bill amends Montana law to prohibit discharging firearms within 500 yards of any inhabited dwelling or outbuilding near Class II waters. It directly affects recreational users - such as anglers, boaters, and kayakers - on public waterways designated as Class II. The key provision adds this specific restriction to existing rules governing public access to waterways, requiring users to maintain a 500-yard buffer from occupied homes. The change applies to all Class II waters without exception, regardless of landowner permission.
