This all makes sense to me I guess... meaning I can understand both perspectives.

But here in Yankee Doodle Dixie, where we don't talk about proof so much as wall thickness, it seems like one could make a careful measurement of wall thickness at every pitted area and determine if lapping/honing the pits out would be pushing the limits of thickness. Surely it's easier to keep a shiny smooth barrel clean and free of ongoing corrosion. Right?

Personally, I would rather buy and shoot a gun with shiny bores, even if honed, so long as the MWT is ok. I would also buy a gun with oversized, aka out of proof, bores as long as the MWT was adequate.

If the pits are out of proof or below MWT, the barrel is shot, shiny or not, right?
