Bronze brushes are bad, but carbon ring is worse and bronze brushes or a polish is the only way to prevent them. Pick your poison. If you don't have a borescope you should not be commenting on this thread.

Do you mean Iosso paste?The pile of patches are from cleaning my barrel with Lasso after 300 rds since last cleaning . ( 25 Creedmoor , has 1200ish on it ) . I was getting pressure signs from my known load . I then grabbed the cordless drill and bronze 223 chamber brush and used Lasso procedure just in the " chamber area" . The black patch is the first patch through after the drill \ chamber brush method. Hopefully it cured my pressure issues. .... I don't use bronze down the barrel. Always nylon for crown purposes.

All you need to know.
We took Bronze brush to bottom of a Ruger M77 SS bull barrel. Ran it back and forth 10 times. Wiped it off and look at all the scratches. We went to patches for the most part and Nylon brushes for the tuff cleaning. I use liquid Wipeout, let sit all night and clean. Then run patch with lacquer thinner and follow with Kroil. Wait all night and clean. Sometimes after a Prairie Dog week it takes 300 patches and some brushing to get spot less.Recently as I don't know which brush is which anymore, I've been cleaning with just patches. Haven't seen anything detrimental at all.
Any comments are welcome.
Just didn't want to jam a brush in there, and leave micro scratches.
