RE: which black powder???
Black Mag'3 is the cleanest, great velocity and conistant. However, the powder is not currently available. Hopefully in 2008 Magkor will be producing BM3 again. Love this powder, but am hoarding what I have left using only for hunting.
777 2&3FGis excellent velocity, consistant, is fairly cleanand is widely available. Shoot about 4-6 pounds of 777 each year.
Pyrodex shoots really well in my experience.However the stuff is filthy,stinks like dead eggs that were stored for three yearsin a skunk's rectumand is about as corrosive as traditional black, so I just shoot traditional black.
Swiss BP is exceptional for taditional black powder. Shoot about 6-10 pounds of Swiss every year.
Goex BP is very good as well.
Goex Pinnacle is available although I have not shot any. Some folks have here on the forum and can give you the .02
American Pioneer Powder (APP)(which also makes Shockey), not shot the Shockey powder but have APP which is about as lame as it get's for a powder in my view.
Supposedly there is a new powder called Buckhorn 209coming out in 2008 from Western Powders Inc. that is supposed to be the next new BP substitue mousetrap. We'll see.
