Ashley Archiblad has written a piece in The Union Democrat which discusses the rise in firearm and ammunition sales in 2009.  It features quotes from store owners regarding the current and future effects of AB 962 on their businesses.  Here's an excerpt:

AB 962 will take effect in February 2011.

“It’s more work for us, which will drive up the costs for customers,” said Bill Adkins of Bear Mountain Guns and Archery Shop in San Andreas.

The ammunition limitations imposed by AB 962 have created some challenges for gun shop owners to keep enough ammunition in stock. Buyers descended on stores trying to get as much as they could before supplies ran out.

“Ammunition has been a tough thing,” Reynolds said. “We’re one itty bitty gun shop and people are buying hoards of ammo. All of those people shopping all of those stores, and ammunition makers can’t fill that pipeline.”

Youngman had to restrict the amount of ammunition she would sell to any given customer to two boxes. When she heard about AB 962 and saw the increase in gun sales, she knew people would be looking for ammunition and started stockpiling herself.

“That’s how we outlasted Wal-Mart and Big 5,” she said.
