You know, I'd like to have just about every shotgun on this thread.
But maybe not for dove.
GP uplanders, IMO, are best when they are portable. While my clays gun runs over 8 lbs, my favorite field guns run between 6 and 7 lbs. And my pick, that SKB O/U, is about 6.75 lbs. Heavy enough to soak up some kick,light enough to carry and swing fast.
