Well I went out yesterday to see what I could find. I found one Citori White lighning in 20G. It is along the lines of what I want but with that kind of coin, I'd like a better fit. The best fitting I found was an old 12G Baikal in fixed F/M barrels. It came to shoulder with precision and was light weight. That's the fit I want so I'll press on. Unfortunately there is very little choice in WPG.
