Let me know if you want wads.
I just punch them with a 3/4 inch wad punch (Bunning's etc) from heavy card and 1/4 inch saddle felt (sourced from a felt manufacturer in Huntingdale, Melb.). I dunk the felt wads in 50:50 beeswax (ebay) and olive oil (coles).
If using 3P (Forbes?) you might want to drop the charge back a little from that used with 2P.
Fiddly, takes time to round up and do, but the enthusiast should love it!
