No Pyrodex for me.
Pyrodex combustion products are actually more corrosive than real black powder.
When chronographing my BP .44 Special and .45-70 loads, I find velocity spread to be minimal, usually within 10-15 fps from round to round. That isn't going to happen with Pyrodex, nor with smokeless. That consistency is probably why I can generate MOA groups out of my 1874 Sharps using good old black powder.
I like the smell of black powder, too, especially when I use my homemade bullet lube, consisting of lard, beeswax, and Crisco.
Luckily, I have a dealer of real BP about 45 miles from me. He spends the extra money on insurance so he can stock the real thing. I usually come home with about 5 pounds each time I visit, plus a bunch of swaged spitzers for my Sharps.
Plus, one can have Goex BP ordered online and shipped direct to their doorstep, if need be.
