NEW ORLEANS — Bullet-makers are working around the clock, seven days a week, and still can’t keep up with the nation’s demand for ammunition.

Shooting ranges, gun dealers and bullet manufacturers say they have never seen such shortages. Bullets, especially for handguns, have been scarce for months because gun enthusiasts are stocking up on ammo, in part because they fear President Barack Obama and the Democratic-controlled Congress will pass antigun legislation — even though nothing specific has been proposed and the president last month signed a law allowing people to carry loaded guns in national parks.

 

Gun sales spiked when it became clear Obama would be elected a year ago and purchases continued to rise in his first few months of office. The FBI’s National Instant Criminal Background Check System reported that 6.1 million background checks for gun sales were issued from January to May, an increase of 25.6 percent from the same period the year before. “That is going to cause an upswing in ammunition sales,” said Larry Keane, senior vice president of the National Shooting Sports Foundation, a trade association representing about 5,000 members. “Without bullets a gun is just a paper weight.”

 

The shortage for sportsmen is different than the scarcity of ammo for some police forces earlier this year, a dearth fueled by an increase in ammo use by the military in Iraq and Afghanistan. “We are working overtime and still can’t keep up with the demand,” said Al Russo, spokesman for North Carolina-based Remington Arms Company, which makes bullets for rifles, handguns and shotguns. “We’ve had to add a fourth shift and go 24-7. It’s a phenomenon that I have not seen before in my 30 years in the business.”

 

Americans usually buy about 7 billion rounds of ammunition a year, according to the National Rifle Association. In the past year, that figure has jumped to about 9 billion rounds, said NRA spokeswoman Vickie Cieplak.
