Apr 18, 2020 · The most practical jackets turned out to be copper alloys, with cupronickel a popular early choice. Cupronickel is 75 percent copper and 25 percent nickel, the same mix found in American fivecent coins, which oddly enough looks "silver." Unfortunately, cupronickel fouling built up quickly, affecting accuracy, and proved difficult to remove.
