I make these from Durofelt brand thick pure wool felt and the lube recipe is 2:1 lamb tallow and beeswax. Not only are they a fraction of the cost of store bought wonder wads, they work about 10x better in my experience. Fouling stays fluffy and creamy all day and comes out with one patch. Keeps the gun shooting accurate cylinder after cylinder, no need to even wipe while shooting. They work that good. Worth making and fun to do. -J.C.F.
