There was a story recently about a inner city crook that stored a loaded gun in an oven and some time after the oven was turnd on for normal cooking reasons the gun went off and hit someone in the home. I would guess this was a loaded gun, not just a box of ammo.
Here it is:

4-year-old boy was stable Saturday after a loaded handgun hidden inside an oven in a South Side home discharged when the oven was turned on, authorities said.
Anthony Smith, 24, of Chicago was charged with two counts of endangering the life of a child and one count of unlawful use of a weapon, said Chicago Police Officer Marcel Bright.
Smith, a felon, had hidden the revolver in the oven in a home in the 4800 block of South Racine Avenue, Bright said.
When the injured boy's sister turned on the oven to cook about 4 p.m. Friday, the heat caused the gun to discharge, striking the boy in the leg with a bullet. His 12-year-old brother was struck on the forehead by a fragment from the gun, Bright said.
Both children were taken to University of Chicago Medical Center. The 12-year-old was treated and released, Bright said.
