Gentlemen,
a big thank you to everyone who replied to my query! The main thing I learned, confirming my suspicions, is that Pyrodex is unreliable and unstable. How else can completely different results be explained? A number of you said it shoots fine, stores well, no problems. But many others tell me it’s not real accurate, very difficult to clean, looses strength and needs hot caps and special nipples to get it to fire reliably. Several responders said it’s extremely difficult to clean, others said it cleans easier than black powder.
So, I guess I’ll order some black powder from Graf, biting the bullet on cost. Whitetail bucks are tough enough to get a shot at, I don’t want to handicap myself with a propellant that may or may not fire, or if it does may not shoot accurately, or May foul my gun so bad I have to spend hours in camp cleaning it in the evenings. Neither will I need to buy different caps or special nipples. I’ve just not heard enough good comments to give me confidence enough to use Pyrodex on a hunt. Maybe on the range, but not on a hunt. Just the same, i do sincerely thank every one of you who took the time to type out a reply to me. I learned what I needed to know.
In my younger and more foolish days I had limited days to hunt and would hunt in wet weather as I didn’t have the luxury to hunt when the weather was perfect. During the blue bird days of hunting Pyrodex always went bang without an issue in my cap lock and the accuracy was fine as long as I did my part but when it was really damp and drizzly I would get hang fires and occasionally a pop but no bang.
When I switched to real black powder all that went away.
I’m going to insert an old quote from Zonie on ignition temperatures below that says it all in my book.

After some research I can say:
Pyrodex is said to have an auto-ignition temperature of 740 degrees F. (Material Safety Data Sheet)
Hodgdon Triple Seven seems to be difficult to find a ignition temperature for.
I suspect that it is perhaps a little less than Pyrodex, at least in the pellet form. Hodgdon says that both the Triple Seven and Pyrodex pellets need a 209 primer to fire them but it coats the rear of the Pyrodex pellets with black powder as a starter while the Triple Seven pellets do not have this starter.
"Black Mag claims an ignition temperature of 345 C while black powder ignites at 300 C." per an article in Blackpowder Journal Vol 1, No 4.
That would be 572 degrees F for black powder and 653 degrees for Black Mag.
When all is said and done, Black powder has the lowest temperature ignition requirement and none of the rest of the new black powder substitutes work worth a damn in a Flintlock.
Because Black Powder has the lowest ignition point I feel that it will always give more reliable, faster ignition in any muzzleloading firearm so if a choice is to be made a person would be wise to use it if they can find it.
