The number of people purchasing firearms has increased drastically over the last year. Gun owners across the nation were facing the very real possibility that Hillary Clinton could become President of the United States, meaning gun control was in the works. Because of that, ammunition sales also increased drastically as gun owners – both old and new – stocked up.

In November alone, the number of ammunition imports jumped more than 200 percent. Over 17,850 tons of ammunition have been sold to civilian buyers over the last 18 months.

“It’s very unusual in an import industry like this to see such a big move,” Panjiva research analyst Chris Rogers told CNNMoney. “It tells you that there’s a customer demand that’s not being met by U.S. manufacturers.”

The last time ammunition imports were studied, they had risen 48.9 percent from May 2015 to May 2016.

Italy’s Fiocchi Munizioni and Serbia’s Prvi Partizan are two of the top ammunition importers in the United States.
