Here are the new laws for California residents facing restriction in ammo sales.
For California residents, beginning January 1, 2018 you'll have to buy your ammo the same way you buy a new gun, through an FFL dealer. If you try and bootleg ammo back into California from another state, and you are a California resident, and the authorities catch you, its probably a felony. And there goes your professional license and, of course, your job, your career and your livelihood.
Starting January 1, 2019, California residents will have to undergo a background check to buy ammo from a dealer, same as the instant check. There may be a fee charged, for that check.
California residents can still buy ammo from the internet for delivery to an FFL dealer in California.
Also in the State of California, if you don't count all your guns, and report any stolen within a certain time period, or if you don't have a child lock on your gun, and some kid uses it, then you go to prison. That's because next year in California, the only way there'll be any legal ammo to buy, will be handled by the gun dealers. But the gun owners, can wind up felons for lending guns to kids or not keeping them locked, or not reporting one stolen. Also its a felony if you do not report a gun stolen within a certain amount of time to the police. I think.
Kind of discouraging to own a large collection in California so maybe some in California are saying maybe I can make do if I concentrate on shooting a couple shotguns. I don't know. All I know is, it stinks, it really stinks.
