Well, I have taken my BP shotgun to hunt alongside modern shotgun shooters . Talk about impatient fellows. So to speed up the loading process, I use 20 gauge cartridges that I make from used bond paper, and a wooden "former" that I sanded to fit the bore with two layers of paper wraped around it. (This gives me a very close fit when I make my cartridges). To load, I tear open the cartridge, and place it in the bore, open end toward the breech. The powder flows into the breech while I remove my ramrod, and I ram down the paper tube on top of the powder to form the wad. Then, I ram down a second cartridge made of newsprint, and filled with shot only. This holds the shot in place like an overshot wad. I don't tear this open as firing will rupture the newsprint without any prep from me. Once done, I cap and am ready. (Note, no lube, so mind the smouldering wads when fire danger is high, eh?) Loads in seconds instead of a couple of minutes. My favorite load is 70 grains of 2Fg with 7/8 oz. of #7.5 lead shot. Hammers pheasant and chukkar from my Pedersoli.
If I was shooting skeet, I'd get a wooden rod, and attach a worm at both ends. One end I'd have a damp (not soaked) patch, and the other I'd have a dry one. At about station four, I'd give the barrels a swipe and a dry, and carry on.

I use paper I harvest from hardbacks I get for sale at the library for $1.00.
