Rob,
I didn't intend to convey that the .008" change to wallthickness was inconsequential, but rather that a reduction in outside diameter by .008 compared to an increase in inside diameter of .008 was likely inconsequential. That comparision would have both barrels of the same wallthickness but different diameters by .008". This diameter difference, IMO, would be somewhat inconsequential in practical application, even though theoretically the smaller tube with the same wall would be able to contain higher pressures.
