These barrels are on a 1910 ithaca 10 guage. While I know this was well into the smokeless powder age, a lot of black powder and damascus was still being utilized on guns of this era. Were the Krupp barrels designed for black powder and the new smokeless powders of the time or just smokeless? I have several damascus guns and love to shoot black powder. I thought if nothing else I could shoot just black powder in it. I would think it should perform the same as any gun with damascus barrels of the time. The gun is in top condition both mechanically and looks. I have a lot of extra shotgun shells from this era in my collection, do any of you gents know if there is any way or anyone who could utilize the powder from these shells for test to learn the pressures powder of this time would have had? I think it would be interesting data.
