Using shot in a rifled muzzleloader

[fatboyz]

I'm expecting Pete or Cat to have some experience here. I have a 50 cal flintlock and would like to do some rabbit/grouse hunting over Christmas. I read a few things on the interweb about using a homemade paper shot cup and leather and cardboard wads to shoot lead shot. Seems like it would work? anyone have any real world experience. I saw a few youtube videos and nothing blew up!
