Several firms offer round felt wads for the purpose. Before using, take something like Ox Yoke lube or TC Bore Butter and put a good smear on each. One side will do. Set out in the bright sun for a bit to melt into the wad (using the Boss' microwave to speed the process gets you numerous nights on the couch and valuable shooting time wasted attending counseling). Keep them in a sandwich bag with your possibles. Ram the wad separately over the powder before the ball and you can do away with greasing the ball externally. Its much cleaner, especially in a holster. In warm weather the external grease melts and runs out the chamber. Also, in summer your Crisco supply has a tendency to go rancid pretty soon. The prepared lubes aren't that expensive.
