You can buy the wonderwads or bore buttons on line from a number of places. I personally make them with a 1/2 inch hollow hole punch and some construction grade insulation felt. Make sure the felt is 100% wool. You can lube then or shoot them without lube. I lube then.

As for shooting the No Excuse Conicials with wads, you dump your powder put the wad in the bore and push the conical on top of the wad. It will not turn on the way down the barrel. The wad protects the base of the conical from the hot gas of the powder ignition. I personally have shot a lot of the No Excuse Conicals but have not used wads.. as of yet. I do intend to try some of them to see if they make a difference.
