Pyrodex was developed for a single reason. Regulations came about for the storage of black powder, and a lot of stores did not wish to invest in the beefed up storage requirements needed to legally keep BP. Pyrodex came about for black powder stores or departments in larger stores, to offer a propellant that "worked" in muzzleloaders, but did not require the special storage.

It has always had ignition problems. If it didn't those new fangled muzzleloader rifles would still be using caps, instead of modern primers, and Pyrodex Pellets wouldn't have that band of more easily ignited material attached to the pellets. :wink: Not to mention the short shelf life, and corrosive qualities.
So Pyrodex has its niche in the shooting community, as it is easier to ship, and easier to store in a retail setting, and when it works it works just fine. I will say that in the sub-category of black powder, for Cowboy Shooting, Pyrodex worked fine in cartridges and shot shells, but that's a topic for another forum. Please forgive me.
I prefer GOEX 2Fg or 3Fg depending on which rifle or gun I'm using, as most of my stuff is flintlock, and it simply works for me in a wider application of situations than does Pyrodex.
