Winchester M1 Carbine bore pitting.

[painter777]

1- Before walking away I'd at least have to swab and brush it a few times over a few days to see the 'After View'.
I wouldn't be surprised if it didn't clean up quite a bit.

2- I've seen my Father do a cleaning with Hoppes #9 and brush then patch on the old Rolling blocks he liked. Finish the night off by plugging the muzzle. Stick the gun up right with the muzzle in a pail and leave the action open then fill with the #9 overnight. Next day he'd repeat running a brush and patches until they came out clean. Finish it off with a light oil and be good to go.


3- Or like my little handicapped buddy would say when I question the bore on his slug gun from the season before: "I'll just shoot it clean"

Sounds worth trying 1 or 2.
