The 12 Gauge Rubber Slug is a non-lethal wildlife deterrent. A Rubber Slug is a projectile that delivers a painful impact without causing injury. This is enough to deter wildlife from aggressive or unwanted behavior. Slug flattens upon impact. Because of this, the pressure disperses, creating a painful experience. We recommend firing into the rump or other fatty tissue to reduce the chance of injury. 12 Gauge Rubber Slugs are only recommended for use in the range of  90 – 150 ft (27 – 46 m). Extended-Range deterrent round to be used between 90 – 150 ft (27 – 46 m). The rubber round flattens on impact, spreading the force to create a painful experience but reducing the chances of injury. This 2¾”, 12 gauge shell is for use in Open, Cylinder or Improved Cylinder-choked shotguns only. Margo Supplies also offers a mid-range 12 Gauge Slug. Mid-Range slugs are for distances of 35 – 120ft (14 – 37 m). A valid PAL and government-issued photo ID are required at purchase.
