What works for me the best is to take a brush, not stainless and wrap some copper thin wire from Chor Boy copper brushes that you can buy at the grocery store. I use a scissors to cut the wire. I place my Revovlers in a vice protecting the barrell by a rubber sleeve over the jaws of the vice. The cylinder is open and I push the Revovler forward in the vice so the crane - extracor is open like you are extracting spent shells. In this way the gun is secure and the brush is much easier to use on the in and out. I shoot some Rem Oil in the barrel and cylinders first and then follow up with clean patches. The thin wire on the Chor Boy brushes wrapped around a cleaning rod brush works miracles on lead for sure. I shoot my Revovlers a LOT, this really works well for me.
