It was hard to hold the calipers and take pictures at the same time. Art to your point, I should have measured both barrels the same and reported the measurements. However, the 16 gauge barrels are definitely narrower. On the two "0" frame 20s I put them on there was a slight ridge/step down from the bolsters to the 16 gauge barrels.
