Muzzleloader
• must not be capable of being loaded from the breech of the barrel;
• 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.
• Sabots or other similar power and rangeenhancing manufactured loads that enclose the projectile from the rifl ing or bore of the fi rearm are prohibited. “Skirts” or gas checks on the base of a projectile are acceptable.
The above are the Montana reg's for Muzzle Loaders in the restricted areas. During rifle season I don't believe there are any reg's prohibiting your muzzle loader.
