(Wired) Everyone knows about 3-D printed guns. Now a hobbyist from Tennessee has created 3-D printed shotgun slugs. Then he sent them to his friend, who took the slugs and blasted away.

In a video posted to internet this week, Jeff Heeszel, a 48-year-old industrial technician from Visalia, California, is seen firing three 3-D printed slugs from a Mossberg 590 shotgun. The first two slugs both hit their targets at a range of about 25 to 30 feet. The first slug penetrated a dart board. “It went right through that,” Heeszel tells Danger Room. And then carried on to penetrate through a water jug. The second slug blasted through a 2×12 piece of pine wood, and then bored a hole in a wire reel. A third slug with a three-pointed front was then fired at much closer range at a mannequin’s head, but just knocked it over.
