Black vs Subs

[Bigdog57]

I have been using Triple 7 for the last few years, as it performs better for me than Pyrodex. I have six cap&ball revolvers and a modern inline ML rifle.
I find the Triple 7 is much cleaner and less corrosive than Pyrodex. No experience with true BP as no one locally sells it.
Common knowledge says Triple 7 is "10%" hotter than BP, so loads should be lowered a bit. I don't find this true, and load using standard BP data, works fine for me.
