I don't use BH209 as I only have one inline and it rarely leaves my gun safe. Almost all my ML shooting is done with my traditional rifles. That being said, Today there seems to be almost as many choices between BP substitutes plus original BP as there are ML rifle manufacturers. What is the best? Who knows and who cares? There is no sense getting into a debate over it. These froums are her to share information and opinions and not to argue the 'mine is better than your's ' argument.
I shoot almost exclusively Goex BP and Pyrodex RS and P. Yeah, it takes me longer to clean my rifles. and yes I swab between shots. But I don't care. To me that is the fun and nostalgia of muzzleloading. If I want to just go out and shoot, shoot, shoot, I'll grab one of my centerfire rifles. And if I really want to save money, I will take a .22 rimfire out and fire away.
