So, I shot my trade-gun today.
I like to clean right after shooting at the range, to pick up most of the stuff, then give do a more thorough job when I get home.
Both times, I filled the barrel with water (cold at the range, then warm at home), let it sit for a few minutes, then poured the water out, swabbed the barrel with more wet patches until they came out clean, then ran dry patches until they came out dry.
Just now, as I finished up the cleaning, I applied some Ballistol to a patch and ran it down the bore. Said patch came out with a brown ring like it was picking up rust, even though the water I poured out of the barrel was clean and clear and the patches I swabbed were clean.
Is this just what Ballistol does? Or should I run a brush down the bore?
EDIT: Just ran a big ol' chunk of unspun hemp rope, my stand-in for tow, with some more ballistol applied, down the bore, pulled it out by a piece of string, and repeated this a few times. The bore is much shiner now when viewed by eye with a flashlight, so I guess that is what I am doing from now on...
