High density 100% wool felt wads, or dry. About .120" thick (nearly 1/8"), the felt can be compressed.
When used in a percussion revolver, the wad is used over the powder and under the round lead ball. No messy grease is needed with Wonder Wads. They safely seal each chamber and prevent chain-firing.
