Ed, as long as you have the Damascus barrels inspected & checked by a good gunsmith and you shoot the low pressure or "lite" loads you should be OK. Many vintage SXS shooters shoot Damascus barrels on a regular basis with out any issues. I just bought some 2-7/8 " 10 ga shells from RST with # 4 shot to shoot through one of 2 10 ga. LC Smith's that I have both having Damascus barrels.
