(WXIA) A Georgia man has lost his leg after shooting a lawnmower packed with an explosive known as Tannerite.

“We get a lot of calls about Tannerite. It can be extremely dangerous if it is not used correctly,” says Walton County Sheriff Joe Chapman.

Chapman released video of the explosion that cost David Pressley his leg as a warning to others.

Tannerite is the brand name of a combination of ammonium nitrate and aluminum powder. When mixed and shot with a high-velocity bullet, it creates a loud noise and explosion.

The manufacturer recommends using no more than half a pound at one time. But demonstrations using up to 100 pounds at one time have become popular internet videos.

Tannerite is legal (though not intended to be used in this way). No charges will be filed.
