Earlier this week, the ATF announced its intention to ban sales of the ammunition, typically used by sports shooters, in the name of protecting law enforcement officers from "the threat posed by ammunition capable of penetrating a protective vest."

The news prompted panic buying, with numerous gun stores reporting a rush of demand for the ammunition.

According to Travis Brunson, owner of Guns on 41 in Ft. Myers, Florida, he is getting calls from customers asking, "whether this ammunition is gonna be banned, how much can I get and what's happening to the price."

"We probably sold 2,000 rounds today, where normally we might sell 100, 200," Brunson told Fox 4. The price of the bullets is also starting to rise.

It's a similar story at Fowler Firearms, where manager Jon Dezendorf said he began receiving calls about the ammunition shortly after the ATF made its announcement.
