It is my first time shooting moly. I generally just snake the barrel with clp after shooting. I picked up some Montana copper killer and liberally applied it to a patch and let it sit for 15 minutes, when I ran a clean patch through...no blue. I repeated the process and still no blue. I don't know if it has something to do with the polygonal barrel or todays barrels have a better bore finish.
Soak a bronze brush in the stuff and brush your bore out and then wait a bit while it soaks and you'll think you killed a smurf.
