If you go to their web site and read the manual it says that the use of any powder other than black powder, pryodex or tripple 7 will void the warranty. I am not sure on this but is BH 209 a black powder subsitute?
You might go to their sight and read the compleat manual and get a better idea, looks like a nice muzzleloader. hope this is of some help.
