Well, I tried it and it worked! I ground up some match heads into a red powder, and then liquified it with water. I then poured the mixture into a spent .22 case ( just enough to cover the bottom). After letting it dry overnight, I charged the case with powder from another .22 case and stuck a #4 buck pellet in the case mouth.
I loaded it into my Remington Apache 77 ( a late 80's run of a nylon 66 made exclusively for Walmart) and POW!! It shot through a phone book at 15 yards with "minute of rodent" accuracy. I can't say that it was a practical thing to do, but it's good to know that just in case, it could be done. I would like to know what powders and in what quantity can be substituted for the .22 powder without blowing something up. I wonder also if enough match head compound would suffice in lieu of powder.
