If this were a melodrama called “Bullets Over the Bronx,” the second act of the production would remain in the genre of mystery. But, spoiler alert: The story probably will not end with a shootout.

New York City will no longer allow millions of slugs fired at police training ranges to be reconstituted into ammunition that could be resold to the public.

The story began when the financially strained city government decided to periodically gather tons of spent shell casings at the Police Department’s outdoor firing range at Rodman’s Neck in the Bronx and offer them to the highest bidder.

They were often sold to scrap dealers, but two years ago the high bidder for more than 28,000 pounds of shell casings was an ammunition store, Georgia Arms, in Villa Rica, Ga.
