30 years or so ago, I had a gunsmith friend who liked to play with wildcats. He would think one up and build it and I would help him figure out how to hand load for it. Today with the www and ballistic programs, etc, it just doesn't, seem to be as much fun as it was back then.
Good luck in your endeavor.
