Digweed shoots 34" barrels on driven birds? The guy must have a pretty fair set of arms. It's one thing to do that in a game that allows premounting, but playing up and down with a gun of that nature can quickly become quite tiring. That's one reason why pairs of guns, built for traditional driven shooting, tend to be relatively light--although the barrels usually aren't very short either, other than on something like a pair of Churchills.
