Walt, I'll let you know s/n and anything else of interest.

Jack, It's all about how they feel between the hands and between the ears isn't it?...and yeah I'm looking for inertia similar to a big 30" O/U. The SxSs are, or at least feel, lighter/faster than the same length target O/U. I can't say the additional 2" of sighting plane is helpful, but I think the added inertia makes it look that way!
