David Pressley of Georgia decided to shoot 3 pounds of Tannerite placed inside a broken down lawnmower. They shot it from distance of 43 feet, resulting in a shrapnel severing his leg.
Please be careful when you are using explosives. Safety rules should be followed in any activity.
1 pound means at least 100 yards away. 3 pounds mean 300 yards.
