BOY and I were able to fill our swan tags the second to last day of the season. The hunting isn't real technical, just stand on a dike on a refuge and wait for them to fly over close enough to shoot. I tipped on the night before, but it landed way into the 'no retrieval' area on the refuge. Not sure the hit was fatal, but...
Switched to Hevi-Shot the next day and we folded 'em. They make a pretty good thud hitting ice...
