I hate to bring this up, but some repeated agressive pushing of heavily oiled sanding cloth (what is the proper name?) with a dowel or cleaning rod, through the barrel will remove a lot of what looks like pitting. Just don't let the abraisive contact the breech of the gun and ejectors, which will round off the square edges.

Bill, are you refering to emery cloth?

Emory paper comes in many grits (no Charley, not the eatin kind) be very carfull with at. You might want to try crocus cloth. It's very fine.
