Disturbing video shows how a Georgia man lost his leg after using explosive shooting targets to blow up a lawnmower.
A YouTube video shows David Pressley firing several shots at the lawnmower before it explodes.
Pressley and his friends were using a product called Tannerite.
An ABC15 investigation two years ago found the powerful targets are unregulated and can be bought in popular sporting goods stores across the country with no questions asked.
The targets are sold as ammonium nitrate and aluminum powder that you mix together. They ignite when shot with high-velocity ammunition.
There are thousands of internet videos of people blowing up the targets, including many in which people add explosive material or stuff the targets inside other objects.
In some cases, shooters and bystanders have been injured when the targets are improperly used.
