Montana Muzzleloader Hunting Season Regulations
During the Montana Muzzleloader Hunting Season, a muzzleloader must not be capable of being loaded from the breech of the barrel and may not be loaded with any pre-prepared paper or metallic cartridges; must be charged with black powder, pyrodex, or an equivalent; must be ignited by a percussion, flintlock, matchlock, or Wheelock mechanism; must be a minimum of .45 caliber; may have no more than two barrels; and must only use plain lead projectiles, not sabots or similar projectiles. Montana is the only state in the country that does not schedule a separate muzzleloader season.
