My last four turkeys were taken with Rem Wingmaster HD #6 (I voted hevi-shot #6) and they seem to work well for me. In '10, I knocked a bird over at 46yds with it. (dropped, flopped, stopped)

I'ved tried Hevi-shot #4, and loved it, but my newer Briley X-full hevi-shot choke tube likes #6 a lot better.
