The Reaper Defense Group Triple Decker 12 gauge shotgun ammo is the perfect protection against home invaders or would-be attackers and is great for hunting as well. The shells are the standard 2.75″ long and contain three separate layers. Each layer has 3 large beads for a total of 9. These layers allow the beads to spread out further and hit larger areas making it perfect for larger targets. This ammo is great for everyday civilians.
