Winchester M1 Carbine bore pitting.

"I'll just shoot it clean"

We had guys in the east coast here that used that method for their .303 hunting rifles...rust or whatnot. Just put a couple ball rounds through it.

Price, price, price. If it is a good deal then the effort might be worth it.

So OP, is this possible? Can you in fact get a chance to clean and examine after? I used to take a pullthrough and bore brush and even a few cotton swabs in a little bag pre oiled to use on a prospective usually .30 cal rifle. It had to come out good or was rejected.
