A black powder rifle of some sort, especially a muzzleloader. Common slang among hunters. So called because a muzzleloader spews out a cloud of smoke along with its projectile, unlike modern guns. Another popular term for a muzzleloader is Boomstick.
"Grab your smoke pole and powder flask, we're headin' for Penn. to catch their black powder season."
