In the olden days (30-40 years ago) you walked into a gun store and
bought black powder in one lb cans in whatever grain size (typically 2-3
f and up to 5f. Now there is a modern substitute which is used in the
same quantities but is not "REAL" black powder and doesn't have a recipe
for making it which is 75% saltpeter (potassium nitrate), 15% charcoal,
AND 10% sulfur (there are other variations in common use by DIY folks.)
For the purpose of igniting CadWeld shots you can leave out the sulfur
(stinks a lot) and use 100 parts saltpeter and 24 parts charcoal. You
want fine powder 4f or 5f. Do not put the ingredients together in a
mortar and pestle or other grinding arrangement. You can grind the
ingredients separately with no worries and then mix them but do not
grind the mixture if you want to keep your eyes, fingers, etc in good
working order.
I have never used Pyrodex black powder substitute (available at Walmart
stores with gun counters and other vendors) so am not qualified to
comment on the efficacy of using Pyrodex for igniting anything much less
Cadweld shots.

Can says black powder for black powder firearms., imported from Brazil to
Arlington, Texas. I could find no reference to Pyrodex. 4f is used in the
flash pan, not the muzzle. I am sure it is the real thing based on instant
ignition and burn time.

Cool, clever substitute. Pyrodex or the real thing? I still have part of a
one pound can of real 4F.

I had a similar problem igniting a Cadweld that had lost its ignition
powder.
Needing to do 99, on a damp day, a little 2F black powder from the
flintlock shooting kit got them to work every time.
