WB
I used simple card wads in .41 Magnum once

and recoil "unloaded" the shot charges. I simply dripped candle wax over the top though and that made them work.

Simply using (2) gas checks, one for a base wad, and a inverted cap crimped in place for standard length cases works fine. The gas checks are metal frisbes that do damage as well. A lazy but effective approach.
