all you boomers out there more power to you if you love recoil and noise.
My .44 1851 Snubby Navy (fantasy gun) nicely digests 15 grain volume of FFFg Black powder or a 15 grain VOLUME of Black MZ and a .451" ball. The black powder load uses a lubed felt wad the BMZ load does not need wad or lube..
I am a to the bone a Black Gunpowder shooter, but I was directed to American Pioneer Powder and found it was as much fun as BP, but was a lot easier to clean. APP fouling is consecutive not cumulative, that is with APP you are always one shot dirty whereas with BP the fouling accumulate shot after shot.
I would recommend if you can't get BP instead of that "P" stuff try to find American Pioneer Powder, Black MZ, or Jin Shokey's Gold all the same product.
So far this year I have shot three pounds of it in various guns both cap and ball and the other kind and am completely satisfied with it.
