I’ll bet you $1 that this new law has zero impact on gun violence in California.

Employees inside the Los Angeles-area gun shop had their hands full chatting with customers who were looking to replenish their ammo supply before July 1, with some customers spending hundreds of dollars in the process.

Why the hurry? That’s the day a new state law will require almost all buyers to go through background checks before being able to buy bullets, potentially increasing the amount of time and money it takes to make purchases.

“We’re probably up by 400% from where we were last year for this past month, and this month, in total sales,” says Daniel Kash, the store’s president.
