Actually, if you look in the regs and look at the manufacturers data for Blackhorn 209 you could surmise that it was legal. NDOW has now determined that it is not legal, and made a note on their website and supposedly mailed notices out to all muzzleloader hunters. The regs say nothing in regards to BH209. NDOW is now basically stating that BH209 is mislabeled by the manufacturer. They're going to have to change the regs next year.
