Keith - good call. I forgot to mention that I did drop a bore light down. didn't see any inside pitting anywhere, but then again it was hard to get enough of a clear "picture" of what was going on all the way down there. I suppose if there was any inside pitting I would have seen it, on the other hand.
I've got 6 other percussion double and one perc double rifle, all damascus barreled of course, and as I said, no pits on them except just a fine spatter on a barrel of one (Purdey 16 bore). As I said, I've taken a shine to this new one, so it's possible I'm being a little picky. Or else it's the fact that the pit(s) are in that "Danger Zone" (first 10 inches after the breech). Ooooh, scary.....
