TXGunNut, people have reloaded .22 rimfire cases.
Grinding up match heads mixed with water to a paste, packing it in the rim of a case then letting it dry. A grain or so of black powder under a cast bullet stuck in the case. Worked fine for hunters in Siberia taking small game. One could get 2 or 3 reloads per case as long as it was indexed in the chamber so the firing pin would strike an undimpled point on the rim.
