As for wads, not all fiber wads are created equal, if you are considering them. Circle Fly cushion wads are pretty useless. The Precision Reloading cushion wads are a good bit better and give more uniform pressures and velocities. I do use CF nitro cards, lubed and unlubed, and they seem fine.
On the subject of wads, I have been using CF wads (over powder, cushion and over shot) in my muzzle loaders and they seem to work OK as near as I can tell. the cushion wads I soak in bear grease. In my .410, I am still working out a load column that suits me and preliminary results show that my latest iteration may be working well but more shooting needs to be done before I can say that I am satisfied. My biggest issue is with fouling. With muzzle loaders it is not an issue as the bores get "cleaned" on loading but with suppository guns, the load only goes one way and the fouling gets pretty brutal after a round of clays and I am not interested in wiping between shots if I can help it. My latest load is 30GR FFF, over powder wad (punched out of waxed milk carton) then a 1/8" felt wad (dry) then another 1/8" felt wad soaked in bear grease (to clean on the way out), then another card wad from milk carton, 1/2oz shot, then another milk carton card, then topped off with bees wax melted and dripped into the case from a candle to fill the last 1/8". I then push a stamp with the shot size into the wax for identification. The wax is to hold everything together but I don't think it does much in that regard since it does not STICK to the brass. If the loaded shells are rough handled I suspect that the wax "wad" could just fall out. Been considering making a die to SLIGHTLY crimp the case mouth so the wax will flow under the crimp and give it good purchase but would rather not if I don't have to. Still experimenting.
