PHOENIX (KPHO/KTVK) -Fire crews were called to the scene of a major house fire in which ammunition was burning and exploding near 12th Street and Peoria Avenue in Phoenix.

According to the Phoenix Fire Department, crews found the body of an 80-year-old man at home.

The man has not been identified, but according to the Phoenix Fire Department, he was a gun dealer who loaded black powder ammunition as a hobby.

In the simplest terms, loading ammunition involves priming a cartridge case, adding a powder charge to the case and then seating a bullet on that charge. The victim reportedly used black powder, which is an easy-to-ignite mixture of sulfur, charcoal and saltpeter, rather than the more powerful smokeless powder used in most modern guns and rifles.
