I have only seen it in Cabela's Shooters Supply catalouge, and it didn't give me that much info.

Is it just a normal steel load with a Flite-Control wad? Or is their a mix of steel and some high-density metal thrown in?

Flite Control wads seem to have worked best for me at about 40 yards, but thats with turkey loads and lead on the patterning board. They weren't really worth a hoot for turkeys, but I can see some real potential in them for waterfowl.
