When used in cap-n-ball revolvers, Wonder Wads are used over the powder and under the round lead ball. No messy grease is needed. They safely seal each chamber and prevent any chance of chain-fires. Single shot pistol and rifle shooters are using Wonder Wads over the powder and under the patched ball to improve accuracy. Slug gun shooters are following the same method with very good results.
