Ive seen literally dozens of 700s over the years with pitted barrels. Nothing special about 700s in terms of barrel steel, its most definitely not seriously corrosion resistant.
No intention to indicate there was anything special about the steel in 700 barrels. Guess the pits must have missed the dozen or so I've owned--currently and in the past--and the dozens more that I've looked at. Hoping to hear from a Brit gunsmith about the prevalence of pitting in Brit doubles of the post-WWII (post-corrosive primer) era. Of course one advantage of British doubles is that the use of plastic wads isn't as common over there as it is on this side of the pond. They're more likely to go with felt or fiber wads for the simple reason that a line of guns could otherwise dump a whole lot of plastic in the course of a single drive (let alone an entire driven day)--which most driven shoots would wish to avoid.
