Just a generalization, but bore pitting is on the inside of structure that is stressed much more highly on the outside than inside. The pits would have to be extremely deep to make much difference in the ability of the barrel to handle pressure, IMO. The fact is that many a gun owner will go thru countless hours of hand wringing over a few pits less than .010" deep and have a number of guns laying around with similar depth engraving on the outside of the chamber area of a gun, a much more highly loaded area.
