In an earlier life when I was hunting for meat for the table we had a pond on the neighbors place that was a hot spot for ducks. The old man was picky about who he would let on but as I worked his hay fields every year, I got in. Luckily, the game ranger didn't.
I had a Savage 410/22 over and under as a boy's first fire arm so... I lifted my eye and rifle over the berm and dropped the first sitting on the water with a head shot of the 22 then caught another on the mas take off by flipping to the 410. Once I accidentally caught a crossing pair and got them both.
Haven't hunted duck since I was 16 or much of anything else since I was 21.
