This subject was discussed on either accurate reloading or 24hourcampfire but I cant find the posts. I believe there was a suguestion that Lothar Walther were doing barrels like that but they were very expensive. From some of the beautiful work shown by some contemory gunsmiths then the ability is very much available providing the pocket is deep enough. Mention an octagon to round barrel with wedding band transition to a competent gunsmith and it will suguest the style of rifle (and the level of spending) you are looking at.They certainly say a lot about a mans apreciation of all that makes a spectacular rifle.
