So some of us were talking in the chatbox about the different priming mixtures used by the US military as well as private ammunition companies over time. Here's a listing from some of my notes. This is mostly historical reference, but may give some people some insight as to exactly what happens in the primer; the sparkplug of the cartridge.

Under no circumstances should you try to actually make priming compounds, sounds like a good way to lose body parts.
