I have been told I am a little nuts so I will ask if anyone might know. I have a 50 cal muzzy and thought it might be fun to work up some shot loads for it. Does any one know of a source for 50 Cal shot cups? I know there are shot cups for a little used it is either 28 or 32 guage that if I remember right that mesures .502. I would if they would work, or if some one has other ideas.
