Currently there are no California laws to forbid ammunition sales across state lines unless it is incendiary/Tracer, explosive, or armor piercing of a type there is a handgun that shoots it (exception made of M855 being classified as penetrator and not armor piercing).
Jan 1 2018 a new law comes into affect for the state that will regulate this. We expect ammo to double in price and become more rare. Come September you should be able to sell your ammo to folks in CA at high prices for the harder to find stuff as we have our own version of Gun Panic 3.2-AMMO RESTRICTIONS STRIKES BACK!
There are currently local laws that forbid such (think cities/counties like Oakland, San Francisco, Los Angeles, or any other city that also likes being called a sanctuary city, or thought Hillary was less corrupt than Trump though the Clintons worked for government all their life and have hundreds of millions of dollars that they did not pay taxes on due to hiding it in a foundation) that will have laws but would not be enforceable to someone living in a red state (your courts would never allow it) unless you came to CA and had contact with LE. The local laws are enforced with the big merchants-that have a CA presence or Federal license so they can sue and get lots of money to support the corrupt CA political system, also it can affect the resident receiving it. You can google for these places but many like sportsmanguide are not accurate and cast a wider net than is reality on the location restrictions.
If you live in a red state you are good to go!
Just don't mail it by USPS as there is Federal laws about that. Use UPS and label with the ORMD and ship from a UPS owned hub and bring the customer service number for ORMD shipments.
