Lightfield has developed a full line of less lethal ammunition for Wildlife Control Professionals. The aversive conditioning of large, heavy muscled animals is a growing trend with specific range demands. The new Lightfield line includes patent pending designs with velocity and kinetic energies calibrated for range specific applications. The new line is intended exclusively for wildlife control and provides effective and affordable solutions for close, mid-range and extended range targets. Lightfield believes ammunition that is safe and effective at close range on humans may be underpowered for large animals at greater ranges. Likewise, loads that are effective at extended ranges may be too powerful for humans at close range. In response to that situation, Lightfield has calibrated its wildlife control line into the following basic classes: Close range 8-25 yards, Mid-range 15-40 yards and Extended range 30+ yard. A patented design available only through Lightfield. The black slug at 500 fps will accurately target problem wildlife for safe and effective aversive conditioning. This load has been used thousands of times against bears and other large animals across the US and Canada. This load is accurate and effective out to 40 yards. Note: The Mid-Range Rubber Slug should only be used in Cylinder or Improved Cylinder-choked rifle barrels only.
