Hevi-Shot is the best shot available, bar none. I can't afford it, but have a couple of buddies that do reload it, and have shot it on a goose hunt or two.
What I have seen with shooting Hevi-Shot is the need to be real careful. I have seen Redheads come buzzing by in a group of 20-25, a buddy cut a close bird (20-25yards), and that bird fall, along with another behind it at more like 60+yards. So it has killing energy well past anything else I have ever seen. Never even knew the second birds was down until we saw a wing waving in the distance. Would have been real bad if we were just needing one redhead to limit. And could have just as easily killed 3-4, if they would have been line up just right.
It is awesome stuff and will do a # on geese. But I can't afford it, so I shoot STEEL. cooter
