There's nothing wrong with Pyrodex, it wins championships as well as Black. Just a few things to remember when using it. 1. It is more corrosive than real black powder so be extra diligent with your cleaning and follow-up. 2. It is more hygroscopic than real black, so keep the lids on the containers. 3. P grade tends to out perform RS grade. At least it has for me. 4. Pyrodex is harder to ignite, I recommend a hot-shot nipple for better consistency.
