Shot one last year hunting a greenfield. I saw him coming in to my decoys and about half way across, he smelled a rat and made a hard right turn. He was about two steps from being gone and I put the dot on his head and shot. I knew if was further than 40 yards but didn't realize that it was actually 63 yards until I got to him and ranged back to the tree I was sitting on. Shot him with 20 gauge TSS #9s.
