Congratulation on your new rifle. If, your are from a state that allows magnification on muzzleloaders I would go with a 3X9 but it depends on the type of hunting you intend to do. I like Bushnell scopes and I heard a lot of good things about Mueller Scopes. I found my Kodiak Pro Magnum really likes Power Belt Bullets with Pyrodex RS powder and W-W 209 primers.
