Having run into issues telling the truth when buying blackpowder I came to the best solution: I made (you can buy inexpensively) a CANNON! Now i can truthfully buy and transport my blackpower. My cannon comes with me to launches and the black powder. No more issues and if its a no fly day I can drive to somewhere on federal lands where it is safe to fire the cannon. Very useful!

But Cannons don't use 4F BP, do they ?

I know I've mentioned this, I think on TRF somewhere before, not sure under which thread, but you CAN use a mortar and pestle to convert 3F to 4F.
It's safe and you are not grinding it into a fine powder, your observing the size of 4F kernals and lightly crushing up 3F kernals to a similar size as the 4F.
It's the same powder! Just don't over grind and don't grind too much at once. A gram or so at a time. You are looking for "average" sized kernals.
Home grinding will give you some that are too small and some not quite small enough. Looking for average.
Or you can buy a mesh to sieve it through, mesh range for 4F is 14 to 20 mesh size (3F is 10 to 16).
Just don't over grind!!!!

I posted this long time ago, since then I went to Bass pro last week, they no longer carry BP in any form.

You can choose to be stupid and play the " not in any rule book I can find, so sell it to me for my rocket" or be smart and play the politically correct game. It is happening slowly nation wide, don't let it happen near you.;);)


I went into a local (Wilmington, NC) Gander Mountain a few weeks back just to kill an hour or so, and I noticed that they don't have FFFFg black powder either. They sell a black powder substitute, but not black powder... :-(
