I must admit that I have not included BH209 in this equation. Although it may be a terrific powder, I have not used it nor do I see myself using it in the near future simply because I personally do not see a significant increase in return for the amount of $ increase. Now don't get me wrong. I am not stubborn nor am I opposed to change. But my experience with good old BP and Pyrodex has been very good. And my shooting with open sights pretty much limits me to 100 yds or less. I know they are 'dirtier' but I don't mind the swabbing between shots or the after shooting cleaning.
For now, let's leave BH209 (and White Hots) out of this and limit your opinions to BP, Pyrodex, and T7. I am curious as to all of your opinions.
