I test fired many different chokes & loads for my SBE ll until I settled upon the factory flush mount full choke and Federal MagShok Heavyweight 3.5" no. 7. The shells are expensive, but any turkey you shoot at within 45 yards will ride in your truck if you hold it 2" below the wattles when you pull the trigger. The full choke that came with my gun measures 0.685 and shoots those Heavyweight 7's (and 6's) considerably better than all the afermarket extended chokes I tried. I even had Rhino custom make me a non-ported version since the FliteControl wad is specifically designed not to be stripped away.
