No, the hoop strength is not appreciably enhanced by smoothing the bores at the loss of wallthickness from honing. This is because the material in barrels is pretty malable with which along with goes resistance to notch fracturing. Besides, the higher stresses are on the outside of the barrel tubes.

My experience suggests that larger bore shotguns aren't as affected in their patterns from pitting as a very small bore (.410 being pretty susceptable to pattern problems from bore pitting).
