Good ol' dirt and particularly clay works as good as the high priced
spread. We've even used dry sand successfully.
The igniter charge is a fine powder packed into the cap. A bump, drop,
etc will knock it loose. One of the reasons I purchased a carton at a
time is they were pretty well protected, but still require careful handling.
I've only had two out of several cartons that were a problem. Alternate
methods of ignition worked well. I'd think goof old 4350 would work as
an igniter and is safe to handle, but have never tried powder.
Eyes and hands are vulnerable when using alternate methods of ignition,
so be careful

This past fall...I put in 18 ground rods when updating my grounding system
and used the cad welds..I purchased them from K7FP along with a really nice
entrance panel...I had a problem igniting a few of them ...he sent me
replacement charges and they worked fine...
The ones I had a problem with...I didn't want to try black powder..or
Pyrodex (both RS and select)...of which I have for my rifles etc...I took out
some Winchester 571 for grins and it worked on one but the others not ...I
did not try any other smokeless powder...The only others I had were red and
blue dot.......and also had an issue with burn thru ...I then used stuff
called babbit rite and stuffed it around the bottom of the ceramic tube and
the rubber...not another problem...You can use duct seal or stuff the
electric company uses to seal wires to entrance panels...used to call it dumb
dumb...not sure the real name...but use something to seal the rubber to the
rod and ceramic and eliminate that issue.
I think Chris talked to his supplier and said that there had been some
issues with ignition of some charges in the past...The correct thing to do
would be to separate the powders...I believe that during shipping that they get
mixed with vibration etc. causing issues...but who am I to say...I have a
few more to ignite this spring...if it ever gets here....all the snow isn't
gone yet and lake Erie is still full of ice...
The one shots are the only way to go...I am impressed with the way the
connections look after knocking off the ceramic body...they will be good till
long after I am under the dirt or wherever the wife puts me!
Good luck and have fun!

For future reference.....does smokeless powder work as well for this?

Yes BUT... sulfur is optional, potassium nitrate isn't in black powder.

From a corrosive standpoint, depending on the metal, the potassium
nitrate is far more corrosive than sulfur.

A word of caution - take the can label literally, since BP sold in
the USA is legal to possess ONLY for use in BP firearms. Any other
use requires an ATF Explosives User Permit, and you don't want to go
there, with required regular inspections of your record keeping and a
federally approved storage magazine. I believe Pyrodex (no sulfur to
corrode the firearm) is subject to the same regulations.

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.

Needing to do 99, on a damp day, a little 2F black powder from the
flintlock shooting kit got them to work every time.
