We used to make our own for the 44. There's still quite a few recipes on the internet. We used cast lead gas checks on top of the powder and punched shoe box cardboard with paraffin to seal on top of a heavy crimp. Sometimes just gas checks top and bottom. Midway used to sell the shot capsules from Speer also. One of my Speer manuals had the load data for the capsules. Never had much luck with them much over 10 feet though, so we quit making them.
