Super stuff, just the sort of thing I hope to do once I get the various prerequisites sorted out.
What load do you use, specifically wadding please?
Lol. I forgot my measure! But found a cartridge hull so cut it to what looked like an ounce of shot. Used about 3/4 the volume for powder.
Wads were thin card+wet leather (with olive oil)+card.
Over shot was half a fibre wad.
