Fox SW barrels are typically heavy-walled and what looks like a cordurory road can be cleaned up with .004-5" off the bore wall. I'd worry a bit about continuous "ring" corrosion that can't be honed out--say at the chamber intersection with forcing cone. We've had a couple of posters here and on a "safe with modern ammo" query state with conviction that you can take the safety margin in these 80-90 yr. old guns for granted simply because it says Fox or fluid-compressed. I had a 3C SW derelict that handled a few Federal game loads without blowing up. So What? The truth is the safety margin is in ONLY shooting SAAMI max pressure loads in guns made in the SAAMI max era. For suspect guns which have been "renewed", buy, reload, and shoot loads with pressures certainly no greater than the standard pressure of loads available when the gun was new. And the Newtonian penalty of heavy shot charges (recoil) does absolutely nothing good for 90 yr. old wood either.
