I shoot a Traditions Vortek Ultra Light, probably almost the same gun as yours. I use the Traditions Smackdown SST 250 Grain bullet (which I believe is made by Hornaday) with 90 grain of Blackhorn 209 powder. I get 1 inch groups with that combo off a led slead at 100 yards. I have read where every muzzleloader is a little different, so you may have to toy with your loads a little. I know I did. Tried 300 grain bullet with 80, 90, and 100 grain of Blackhorn, and the 250 grain bullet with 80, 90, and 100, and any other combo other than the 250 with the 90 threw my accuracy way off, like 4-5 inch groups at 100 yards. Also, I use Federal 209A Shotshell Primers, as I found these work with the Blackhorn the best for me.
