Mr. Grilley "thinks" differently but properly wadded per BP's direction I would have no issue shooting ITX or Niceshot in a damascus gun.

We seem to have stated the same thing. As long as you use proper wad protection (like we both stated) using any of the tungsten based shot should not be an issue. Not sure why you need to point out that I "think" differently when it seems we have said the exact same thing.
I brought up the point about shooting the shot "naked" since some of us use card wads in our antique guns, with no modern wads to protect the barrel or shot. If someone is willing to put a few hundred rounds of tungsten based shot through their D grade damascus barrels with no wad protection to find out if it will scratch them they have my blessing, I'm not willing to risk mine.
While working as a machinist and mold maker, I use a variety of different abrasives on almost a daily basis, including many that are embedded in a "soft" media such as a polymer. Tungsten combined with anything is going to be abrasive to all types of steel barrels, no matter how soft the finished pellet is. For example tungsten on the Mohs scale of hardness is listed at 7.5. Steel runs between 4-4.5. The Mohs scale is not as specific as other hardness testing scales, but it is good for general comparisons. Lead is listed at 1.5. As long as the barrel is well protected by wadding (like all of us suggested) it's use should not be a problem. The point about proper wadding can not be stressed enough. Follow the manufacturer's loading recipes to the "T".
