California's gun laws are even tougher this morning. Starting Monday you have to pass a background check to get ammo in California.

That means waiting longer and possibly paying a little more. Advocates say this will help keep bullets out of troubled hands. Critics say it takes away law-abiding gun owners' rights.

The new law was part of Proposition 63 that was passed by California voters in 2016.

In addition to the background check on ammo, the new law

• Outlaws possession of ammunition magazines that hold more than 10 rounds
• Makes it a crime not to report lost or stolen guns
• Provides a process for taking guns from people upon their conviction for a felony.

"It was a repudiation of the National Rifle Assn. and the gun lobby. They lost badly," Governor Gavin Newsom said in an interview back in 2016. "It’s a very important initiative because I think it’s the beginning of a national debate on relinquishment (by felons) and ammunition background checks that will I think will have a very significant impact on reducing gun violence in this country.”
