In 1988 during a shoot out with a subject one of our guys was armed with a 12 ga shooting 1 oz foster slugs. He hit the guy at about 30 ft from the side in the left upper arm nearly removing the arm. The slug then entered the chest taking out a rib. It then continued thru both lungs and clipping the top of the heart and removing the aorta, then taking out a rib as it exited the chest cavity. It then took out most of the bicept on the right upper arm. The slug was never recovered. DRT. When we opened the chest cavity it looked like everything above the diaphram had been run thru a blender.
Slugs work and work well.
