The Remington 1889 Hammer shotgun is/was built like a tanks... I know I have three, one Is converted from 12 gauge Damascus barrels to 20 gauge modern steel fully rifled, one is a ten gauge converted to 12 gauge modern steel, and last one is original (fluid) steel softer then modern steel. The bar, bridge,face and flats were all very solidly built. The barrels not so much. I have shot all of them with the appropriate load,ball, slug and shot for the applicable gun with noissues, but all do not exceed pressure levels for the barrel considerations...keep them in good repair and keep shooting....wonderful feeling shotguns.
