Inventoried cache of black powder & substitutes not in flasks/horns. 19 pounds left plus 150 pellets. Can't recall the last time I bought powder - sometime around 2004. Unopened Hogdon cans are marked $2.79 for FFg, $3.00 for FFFFg. Dupont Fg was $2.25. Elephant had no price, neither did Clear Shot. Two pounds of "blasting powder" (quite crude) still in a glass jar from the 1960's was hiding in the back.
Thanks to this forum, my ML interest is renewed, even tho' my buds are all dead and there are no "shoots" within 100 miles.
While the old powder in sealed cans still makes smoke, old caps have proved more "disappointing than devastating". Flints were a better investment.
