Last year a buddy gave me three boxes of hevi shot #4 because they wouldn't cycle through his Stoeger semi auto. They were the best shotgun shells I've ever shot but I refuse to pay $25 + for a box of shells. This year I sprung for a box of black clouds and I liked them but not as good as the hevi shot and still expensive. I've been hunting with the Winchester Super X and they are definitely not black cloud or hevi shot but if I wait for shots inside 30 yards they knock them down just fine.
