Hurricanespg - you bring a good point. But for me, ill be shooting the Nitros 4x5x7 hevi-shot and plan on taking UP TO 40 yard shots. If i HAVE to ill go a little further, but i still plan on taking the closer shots. So i know i have a wonderful pattern flying out of my gun and feel extremely confident that it will be lethal within that range. The question of #7's penetrating past that yardage has an answer beyond anything i know. But i do know that within 40 yards its a dead turkey.
