Has anyone EVER been able to make the subs work as priming powder? I know it's reputed they don't work well, but will they EVER work? It would seem that witht he sparks at 2000 degrees, and the flash point of the subs around 850, that the math would certainly indicate they would, in theory work. I'm not going to waste my time trying (I have enough to keep straight and manage at the range as it is to conduct science experiments).
As has often been seen, even a blind pig will occasionally find an acorn so, "will they EVER work" ?
Undoubtedly the answer is yes.
Will they work reliably to ignite the main powder charge. IMO, the answer is, No.
As I've mentioned several times on the forum, for the powder in the pan to reliably light the main powder charge, the prime must burn with an instantaneous "POOF!!" that only black powder will do.
The slow "fizzle, fizzle, fizz" that the substitute black powders do when they are ignited out in the open air may or may not make enough flame to light the black powder inside the vent hole.
I suppose if the substitute powder completely filled the vent hole and pan and if it also actually lighted it would make the gun fire.
About the only good reason I can think of for trying to use the substitute for priming a flintlock is, you are out in the woods all alone.
You have used up all of your black powder for your flintlock. All you have is some substitute black powder.
You hear a noise and its getting closer. It's the dreaded blood sucking vampire zombie and it is looking for YOU.
You charge your trusty flintlock and pour some Pyrodex in the pan. Closing the frizzen, you wait.
Suddenly, there it is! Just a stone throw away!
You **** your flintlock, raise it quickly and pull the trigger.
Fizzzzzzl, fizz, fizzzzzzlll.......
BOOM. The cursed thing drops to the ground wheezing and gasping. Then, all is silent.
"CUT! CUT! It's a take! Everyone, report for the next scene over on stage 7".
