Saw this on Zombie Squad:
Some info on the vid:
Targets are pumpkins already destroyed by AK-47 fire. The shotgun used is a Mossberg 590 which the shooter mentioned he keeps around just for "experiments" like this.
The round fired is a dragonsbreath round; loaded with powdered metals, it produces a significant flash for a few seconds, but not much else. Low recoil, they're only suitable for break-open or pump shotguns as there's not enough energy to cycle the action of a semi-auto.
Not much practical use, but does make a neat video.
