The Annihilator Slug is half metal jacket soft point slug weighs 485 Grains and carries 2565 ft/lb energy while traveling at 1540 ft/ps. This round is an extreme defense for anything that walks. The Annihilator slug is a premium half copper-coated 485-grain slug. The half-metal jacket refers to the copper coating of the slug that only covers the sides and back of the slug and provides less friction than a standard naked lead projectile. These slugs are specifically designed to travel at a high velocity and expand on impact creating an enormous amount of energy and knock-down power. Typically copper coating is only seen on rifle and pistol ammunition but we adopted this same benefit in our 12 gauge round which makes for a top-shelf quality cartridge. Sold in a 5-round pack. 12 Gauge 2 3/4"
