Starting Jan 1st 2015 CA now requires a Hangun Safety Certficate (being renamed the Firearm Safety Certificate) for the purchase of long guns (cost is $25 - $30). But make sure to check out the exceptions because there seems to be a lot of confusion around this new rule.
One exemption says that anyone with a valid hunting license is exempt.

There are a variety of FSC requirement exemptions. In addition to the previous HSC exemptions, a person issued a valid hunting license is exempt from the FSC requirement for long guns only [Penal Code 31700(c)]."
