Dangit I need some 4f to use for black powder season
I never bought 4F until I found an almost full one pound can at a gun show a couple years ago for only $5.00. A pound of pan powder will last a very long time, even for an active flintlock shooter.
Prior to that, I just would grind my own 3F or 2F in a make-shift non-sparking mortar and pestle consisting of a ceramic ashtray and a plastic screwdriver handle. I just grind a small amount at a time, in case it should go off for some reason. I never had a problem.
