Montana bowhunt broadhead rules
Montana Fish, Wildlife and Parks (FWP) requires a bowhunter education certificate for any archery hunt and specifies both broadhead width and blade-count minimums in the annual regulations. Both fixed and mechanical broadheads are legal for most big game archery hunts.
The rule
MCA 87-6-401 and the FWP Bowhunting Regulations require: bowhunter education (National Bowhunter Education Foundation certificate or equivalent) is mandatory for any archery-only license. Broadheads must have a minimum cut width of 7/8 in, at least two sharpened cutting edges, and must be sharpened at the time of hunt.
Blade count and minimum cut
Two cutting edges minimum. 7/8 in minimum cut width. Sharpened at hunt time (a dull broadhead is a violation).
Species restrictions
The rule applies to elk, mule deer, whitetail, pronghorn, black bear, moose, mountain lion, mountain goat, and bighorn sheep hunted with archery. Montana’s Bowhunter Education certificate is the entry gate; you cannot buy an archery-only license without it.
What this means in practice
Every mainstream broadhead is legal. The bowhunter education requirement matters more than the head choice: the class is a one-day or online course and the certificate is transferable to and from other bowhunter-ed states. Mechanicals (Rage, SEVR) are legal. Fixed (Iron Will, Slick Trick, Cutthroat, G5) are legal. Barbed heads are not permitted.
