I hear a lot of people say a 20 gauge can't be a goose gun. I would tell them it shouldn't matter if you are a good shot. I shot one goose this past weekend at 40 yards with my 20 gauge with an imp. choke and Hevi-shot #6. One pellet right threw the chest. He flew about 100 yards and fell from the sky.double clucker said:I had two women hunt with me Sunday afternoon and Michelle was worried that her 20ga wasn't enough gun and I told her that is what I shoot. Couple hours later we each shot a limit of big geese (12lbs). Put em on the deck and a box of shells will go along way.
