Triple Ball 12 Gauge 2-3/4" With 3 72 Caliber Rubber Balls  This is a 3 round pack.  This 12 gauge 2.75" cartridges launch three large 72-caliber rubber balls, which could provide a less-lethal result on target if carefully fired away from the head and face and not at extremely close range. While these rounds still could be lethal, they provide an effective deterrent for large, tough angry animals and predators. Law enforcement and police may find these to be an acceptable choice for riot control use. Made In United States of America Make sure to read our Shipping Policy.
