Regarding rust my 6 Brownings are no different than my other guns. And, 5 of the 6 have been worn well enough to have a lot of silver showint through the blue.

Regarding chamber rust, it's mostly from the salt and acid that transfers from your hands to the shell casings. Guys who reload and shoot in the heat of summer see a lot more of this.

Chrome lined chambers help with this.
