The 12 Gauge HV Star is a high-velocity wildlife deterrent. The HV Star 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. HV Stars are only recommended for at a range of up to 60 ft (18 m). This 2¾”, 12-gauge shell is for use in Open, Cylinder or Improved Cylinder-choked shotguns only. A valid PAL and government-issued photo ID are required at purchase. For non-wildlife professionals please see Mega Flash Blanks as an alternative
