Which softwood do you use, and where do you buy your saltpeter and sulfur?
I've made a small batch with drug store saltpeter and sulfur, with charcoal I made from tulip poplar and white pine. It burned well, but not as fast as commercial. It would be great for longrifles and fowling pieces.
I don't know yet if my burn rate was hampered by one or more of my ingredients, or if it was the method I used for making it. I used a mortar and pestle to grind my saltpeter. I used a rock tumbler to grind the charcoal.
I think I need to put more lead balls in the tumbler and mill the charcoal longer.
I wanted to get a 2 drum tumbler from Harbor Freight, but the price has over doubled in the last 5 years.
Be forewarned, there are some grannies here who will warn you against making it and insist that you will kill yourself doing so. They will cite the safety protocols used by commercial powder mills and the accidents those makers have had. What they do not take into account is the fact that there is a different level of care taken when you are making it for yourself as opposed to someone who is doing it as a daily grind. There is a level of complacency that affects folks on the job that won't affect a hobbyist who understands the risks and safety measures.
I haven't had time to make any in a few years. It's easier, though much more expensive to order it from Powder Inc. I have too many irons in the fire and the poudre noir has fallen by the wayside.
I'd like to see someone experiment with white and red powder in their smokepoles and I'd also like to see someone experiment with ammonpulver for their cartridge arms.
Nevermind the ammonpulver. I found some info from people who've made it. The fact that it degrades at temps of around 90 degrees F is still the main problem. IIRC, the AN crystallizes and it can detonate and blow up yer boomstick. Big problem. If that could be overcome, it would be a great replacement for smokeless and BP. It burns with no smoke and little to no flash.Of course, you'd have to clean your smokeless gun like it was a BP gun. Otherwise it would rust up since AP is hygroscopic.
