*I AM NOT ADVOCATING THE FOLLOWING! INFORMATION PURPOSES ONLY*
US TM31-210 (Improvised Munitions Technical Manual) details how to reload spent primers using the tips(only) off of strike anywhere matches. The friction sensitive tip is mixed into a paste, carefully packed into the reformed primer cup, anvil replaced, then reseated into the brass. The remaining match head powder (the non-friction sensitive) is loaded as your powder. I would imagine that the same principle could be applied to a rimfire.

I once knew a young man who tried it once, and one time only, to reload a .32 S&W Long with a pencil eraser. The red rubber eraser was deeply embedded in a palm tree. Foolish young boy. That was an extremely stupid thing to try for kicks.
