I spoke with a riverside county sheriff deputy he said u can but ammo must be in trunk. Is this true please reply soon
Not true.
There are no ammo transport provisions in the California law. The only restriction, is to not have it in a position to be fired:
1) No cartridges in the cylinder of a revolver.
2) No cartridges in the chamber of a semi-auto.
3) No loaded magazines inserted--regardless if the chamber is empty.
Ammunition and filled magazines of any amount can be transported anywhere in a vehicle, including the carry case of the firearm.
Any amount of ammunition or filled magazines can be carried on the person. Magazines should not be carried inside a pocket, as that can trigger a separate charge under certain circumstances--they can be considered carrying concealed--. Magazines should be carried in specific holsters, openly on the belt.
Loose ammunition can be pocketed. Filled speed loaders for revolvers can be pocketed.
I carry 40 rounds in 4 magazines on my left side, 1911 in a competition Hogue speed holster on the right (or a Blackhawk "NRA" Sherpa on occasion). The Hogue allows really really open carry
