Sawdust- Before you condem me for not sifting through page after page of law to satisfy your curiosity perhapse you should do the reading yourself.
If you have any refuting evidence please offer it up, but keep it free of harsh attitudes.
It takes a certain amount of time to research a subject like this, and while it takes just a few seconds to sumarize previous readings of the material it takes a fair amount of time to prepare a lengthly discussion.
Anyway here is some of the documentation that I found.

Section 5.
Loaded Firearms in a Public Place
It is unlawful to carry a loaded firearm on one's person or in a vehicle while in any public place, on any public street, or in any place where it is unlawful to discharge a firearm (Penal Code 1231(a)(1)
A firearm is deemed loaded when there is a live cartridge or shell in, or attached in any manner to, the firearm,
including but not limited to, the firing chamber, magazine or clip thereof attached to the firearm. A muzzle loading firearm is deememd loaded when it is capped or primed and has a powdercharge and ball or shot in the barrel or cylinder (Penal Code 12031(g)
For the purpose of Penal Code section 12023 (commission or attempted commission of a felony while armed with a loaded firearm)
a firearm is deemed loaded when both the firearm and the unexpended ammunition capable of being discharged from the firearm are in the immediate possession of the same person.
Note, this section goes to the spirit of the law, and the common deffinition of what a loaded firearm is
It is unlawful for the driver of any motor vehicle, or the owner of any motor vehicle irrespective of whethere the owner is occupying the vehicle, to knowingly permit any person to cary a loaded firearm in the vehicle in violation of Penal Code section 12031, or Fish and Game Code sectoin 2006 Penal code 12034 Also, see "Other Prohibited Acts, Page 49.
In order to determine whether a firearm is loaded, peace officers are authorized to examine any firearm carried by anyone on his or her person or in a vehicle while in any public place or on any public street or in any prohibited area of an unincorproated territory. Refusal to allow a peace officer to inspect a firearm pursuant to these provisions is, in itself grounds for arrest (Penal Code 12031)
This allows for an officer to inspect anyones guns, regardless of permit status, furtuer grounds for arrest are specified in the CCW permit application

Loaded Firearm Defined
171e. A firearm shall be deemed loaded for the purposes of Sections 171c and 171d whenever both the firearm and unexpended ammunition capable of being discharged from such firearm are in the immediate possession of the same person.
In order to determine whether or not a firearm is loaded for the purpose of enforcing Section 171c or 171d, peace officers are authorized to examine any firearm carried by anyone on his person or in a vehicle while in any place or on the grounds or any place in or on which the possession of a loaded firearm is prohibited by Section 171c or 171d. Refusal to allow a peace officer to inspect a firearm pursuant to the provisions of this section constitutes probable cause for arrest for violation of Section 171c or 171d.
Imidiate posession = loaded in magazine = quick to make firearm functional
So in summary, I know for a fact (as illustrated above) That there is an extremly good chance that it will be construed as illigal to transport ammunition which is loaded in a magazine or clip thereof the firearm being transported. as it constitutes ammunition being in immediate posession.
The exact legality is relative to how nice the officer wants to be, how nice the judge wants to be, and how good of a lawyer you can afford. Its subjective, and in any subjective case, without a letter from the DOJ stating that its A-ok, then there is a darn good chance its going to get you in trouble, get your guns taken away, earn you a free nights stay somewhere and signifigantly depelte your bank account
Go ahead, do whatever you want, its your money/time/life thats going to be wasted on legal fees and court time.
If you admit to having a firearm (or you have a ccw which offers probable cause that you have a firearm), you have to allow the officer to inspect it to make sure it is the one on your permit, or if you don't have a permit to make sure it isn't loaded, refusal to allow the police officer to inspect the car for suspected firearms IS probable cause for arrest and they search it anyway.
Personal attacks and demands that I pull a post are uncalled for, and I don't feel that it is in keeping with the spirit of The high road. Its one thing to offer a correction and put your opinion forward for debate, its another to demand that someone pull their statement on the grounds that it had not YET been substantiated. this is an open forum for mutual discussion and education.
I don't mind being proved wrong, but there should be a certain amount of decorrum and courtasy, this community is what WE make of it.
