I shoot NFB in my damascus A. Henry and no issues what so ever. Most of the damascus barrels are very high quality. Modern powder = no smoke screens to warn neighboring tribes. Just dont go overboard with the percentages. I have loaded up to 46% of the BP charge with smokless and no issues. My rifle regulates best between 38-42%.

Im with Curl. Anyone wanting to ditch their damascus doubles let us know and we will find a good home for them!
