Black Powder 209 Primer

Muzzleloading rifles are considered primitive weapons and hunters choosing to hunt muzzleloader only seasons are often able to take advantage of special opportunities not available to modern center fire rifle hunters.  To maintain the primitive nature of the sport, Idaho has limited some technological advances that would compromise the primitive status of muzzleloading equipment. Current Idaho law requires that during a muzzleloader only hunt, the weapon is equipped with an ignition system in which any portion of the cap is exposed or visible when the weapon is cocked and ready to fire.  Also, the muzzleloader must be equipped with a flint, percussion cap or musket cap, 209 primers are prohibited.  These and other weapon restrictions can be found on page 98 of the 2015 & 2016 Big Game Seasons and Rules brochure.
