Recommendation? -- I have no dog in this fight. I recommend that you use whatever you like. Every grain size will work. I have a slow motion video of a Siler igniting Goex cannon up-side-down. The chunks were like coal - you needed to move them around in the pan to get the frizzen to close. Was it slower than Null B? sure

I am sure I would get an F grade on that!
Excellent notion. I have been pondering a new lathe project. walnut mortar and pestal will do nicely. cheers! :thumbsup:paulvallandigham said:If you screen 3Fg powder through a 50 mesh screen( Mcmastersdotcom), ( the closest you can get to a screen with 46 mesh per inch), the fine powder that passes through the screen will give you plenty of "flash powder" to use for priming a flintlock pan. According to my Hodgdon Data manual, 4Fg powder should pass through a 46 mesh per inch screen, but not through a 60 mesh per inch screen.
The first time Peter and I screen some FFFg powder, we though the "fines" we got through the mesh were just carbon edges knocked off the granules of FFFg powder. Then we tried the Powder in a flash pan.
WOW!
Does that go off fast-- faster than 4fg powder.
This is safer than using a mortar and pestal- soap stone or not-- to grind up powder to make flash powder. A wooden pestal would be the wiser tool to use, BTW, as it makes a much lower risk of creating sparks. Wood is an insulator, and doesn't allow static electricity to build up. :hmm:

4f has 2 known uses. Priming fintlocks and it was used in small cartridges in small amounts. A friend had pulled apart a UMC 38 S&W and found it loaded with a less than full capacity charge of a powder eyeball identical to FFFF.
why wouldn't you use FFFF for blanks? it's not pushing anything.
But this was probably not more then 12 grains at the most maybe less. I did not get to weight it.
The only time I use FFFF in a bore is when tricking 5 grains or so through a vent to get a ball out. This is the often ignored advantage of FFFF or Swiss Null B is that it will pass through a 1/16 or smaller vent easily.
This one reason I use FFFF or now Null B to prime.
BTW ground up FFF does not work as well as fine granulated powder does.
