Flintlock Muzzleloader Season: Only single-barrel long-guns with a flintlock ignition system are permitted. The firearm must be an original or reproduction of a gun used prior to 1800, which is .44 caliber or larger, with iron, open "V" or notched sights (fiber-optic inserts are permitted). A flintlock ignition system consists of a hammer containing a naturally-occurring stone which is spring-propelled onto an iron or steel frizzen, which, in turn, creates sparks to ignite a gunpowder. Flintlock hand guns are not permitted. Flintlock muzzleloader hunters may use "any single projectile," including sabots, and mini and maxi balls.

Antlerless Muzzleloader Season: Any long gun muzzleloading firearm, including in-line and percussion sporting arms. Use of scopes and other lawful sighting devices is permitted. Fiber optic inserts may be used.
