The round fired is called "Dragons Breath" a buddy of mine with a gun shop gave them to me. It is a commercial round made with magnesium pellets and shards. They are legal in Washington State. And a lot of fun to slip into your hunting partners gun.
My son missed that pigeon in the video but it will smoke them. The Spinone in the video is very steady to wing and shot and did not twitch. His handler had no idea what we had set up..
Sometimes you just have to have a little fun...
