The Model 1889 Remington was made through 1908 in 10, 12, and 16 gauges. In the 19th century, 10 gauges were quite popular and not just for waterfowl. The typical 10-gauge load was just 1 ¼ ounces of shot. The higher-grade guns had Damascus barrels, while Grade I guns had barrels made of “decarbonized steel,” which is a confusing name, since all steel has carbon in it. The term refers to the Bessemer steel making process.
