TXRam,
By the time the 230 .338 Fail Safe was introduced, they were using moly.
I removed the moly with a product from Bore Tech called Moly Magic, designed for cleaning moly buildup from barrels. At first I tried rubbing alcohol and acetone. They didn't do much to the bullets I had, but other people have reported them working, probably because of differences in how firmly the moly was attached. (Some insist on calling it "moly plating," but to me plating means a hard coatings, and moly isn't hard.)
I'd dump a box of bullets in a small Zip-Lock bag and squirt a little Moly Magic inside, then let the bullets soak overnight. The next day most of the moly wiped off easily with a paper towel, though on some bullets rubbing with XXXX steel wool was necessary (the reason I believe moly-coating attaches more firmly to some bullets than others). Afterward the bullets were copper-colored, but often retained a slight hint of gray.
