I once took a guy dove shooting at our club. There were tons of birds presenting lots of good shots. He shot 6 boxes, ran out of shells and still didn't have his limit. I had long since finished so I gave him the rest of my shells and he shot those up too. I think he did finally get his birds but it took him 7+ boxes. I'd guess he averaged about 12 shells per bird. First and last time I took him.
