I've been using the Federal Mag-Shok { 1 5/16 oz #5 lead shot} with flite control wads out of my 20 gauge Browning BPS with the factory full choke tube for the past couple of seasons. So far I've pounded 3 turks decisively at 37,42 and 46 yards. My 12 gauge will be spending alot less time in the woods from now on.
