I haven't tried BH209 yet and I don't foresee me using it either. Only because I shoot sidelocks. I only have one inline and that shoots a Pyrodex load very good. From what I've read, BH209 works best with heavy charges. My loads (except one rifle which is a powder hog) are either 80 or 90 gr of FFg, FFFg, Pyrodex RS or P depending on the rifle being shot. I have a T/C Hawken flinter that used 100 gr of FFFg. That's a stout load.
