I have used all types of shot (steel, Hevi-shot, and Tungsten) and I perfer to use the Tungsten the best. It does cost more than the steel but the results are well worth it. I shoot Federal Tungsten Polymer 12ga 3" #4 for ducks and Geese. The knock-down power is incredible. I tried the Hevi-shot when it came out last year and found that it didn't have the speed, energy and consistent pattern of the Tungsten. And the steel just doesn't do much at all. So in my opinion you should try a box of Tungsten and see for yourself.
