Here's a wildcat that is of some significance to S&W collectors. It is the Harvey K-chucker which is before the Jet! It starts out a 22 Hornet and ends up fitting in the cylinder of a standard K frame with a 35gr Sisk(long gone) bullet! However, the new Hornady plastic tip pills work great! This cartridge had none of the sticking problems of the 22 Jet.
