I had the same thing happen on me this past week with a mallard. One shot to bring him down, thought he was out for the count. Started flapping around on the water so I shot twice more with him being right in the center of my pattern. As I got closer he swam off so fast I couldn't get to him which really aggravated me! That dude MUST have been wearing a kevlar vest!!
I'm using #4, but I'll try some #6 for my swat loads!
