Duck shooting in Nova Scotia is almost all-saltwater shooting, and in a lifetime I've never seen a problem with rust. We just clean guns when we get home, before we kiss the wife and kids, do our chores, or eat. Guns come first. Rust is a myth where gunners set aside, what, seven minutes to clean one?
There's not a speck of rust on my rack of doubles dating from 1899 to 1938. (The "new" SKB is nearly 40 and, like the others, exposed to everything the North Atlantic can throw). I don't understand the need for beaters or anything less than the guns we bought to hunt ducks with smiles on our faces.
