Here is the write-up "My homemade black powder" - Cast Boolits Linked are instructions on making blackpowder. Some consider an old flintlock as an ideal survival firearm if an event puts you into the 1700s technology. Not sure I agree (not sure I disagree either), but black powder has other dynamic uses as well. SS
Very Nice write-up... I keep proficient with my BP firearms, as I hold them, as my Ultimate Backup Weapons. I have two 50 Cal Rifles, My Ruger Old Army .44 in Stainless, and a .45 Cal Tower Flintlock Pistol. My 10# of FFFG will keep me in Powder, for a very long time, and I can compound my own Powder, from local ingredients, should I begin to run low. ..... YMMV.....
