Others already commenting have about covered it ! Only significant draw back is the really close shot. The patterns are so tight that you are essentially shooting a 1" - 2" wide rifle bullet. It is just made up of bunches of closely piled up shot. A few years back I missed a nice bird at about 7 yards. It came in behind me, crossed in front and spotted me. It was about to skedaddle. I took what I thought was a well aimed shot, but flat missed.
