Long time favorite of mine for 1911 barrels. I wrap it around a blue Nylon brush from Iosso and go back and forth until I can feel the barrel just start to get warm... that usually does it, if not, reorient the brush and repeat. Strong pref for the Chore Boy but the finer-spun stuff works too.... not quite as well though. Plus it's made in China and Chore Boy is made in Mexico....
at least that's closer.
