I experimented quite a bit with rebuilding fired primers, and shared the information on CB many years ago. The original procedure involved cutting the tips from "strike anywhere" matches, and using them to reactivate a primer. The instructions were in the Armys "Improvised Munitions Handbook". It caught on quite nicely, and was pretty popular during the second great primer famine. A short while later, strike anywhere matches were "improved", to contain less phosphorous (I believe), and the procedure fell into disuse. I do have information around here somewhere on how to make different priming compounds. The question is.... where?
Hmmm, do I detect a small thread drift? Here?
