I searched locally for "Chore Boy" to no avail. Found one product that honestly labeled "Coated" copper. Another -at CVS - figure that out - was not "Chore Boy", even though a website search said they had it, but a substitute that did not respond to a magnet. I bought that. I cut an "envelope" of the mesh and covered a nylon bristle brush with it and an appropriate solvent and cleaned the barrel and cylinder of my Thomas/Uberti 1873 .45 Colt with it with a satisfactory result.
In retrospect I wondered why we just don't use the contents of an old piece of 18-Ga lamp cord wire?
