I'm not sure if there is a exemption for muzzleloaders or not. But a 50 cal rifle is a no-no I know a person with one. I believe he paid 13,000 cdn for it now your just supposed to hand it over to them for free. Sounds fairSo my 50 cal. Muzzle loader would be an assault rifle haha. I love that thing. One hollow point and no whitetail buck is walking away. I don't have to track these days haha
