A lot of people would probably like a 12ga BSS with 30" barrels as a sxs Sporting Clays gun, or for waterfowl (with steel-capable choke tubes, or the chokes opened) or maybe turkeys. Most sxs lovers would find it way too heavy for upland hunting. There are not a lot of them out there with 30" barrels. That being said, I saw one in a "big box" sporting goods store a couple years back with a price tag of $1150. I figured someone would snap it up for one or more of the above purposes . . . but it sat for a very long time.

Personally, if I wanted to chase down a relatively modern sxs with 30" barrels, I'd look for one of the Ithaca SKB 12ga Magnums. Not many of them out there either. They're a good bit lighter than a BSS, and I think they might work OK both as an upland and Sporting Clays gun (with choke tubes).
