Keep in mind a few things wrt ammo storage:
- The CMR puts this under the State Fire Marshal's jurisdiction. Therefore, any enforcement is under your local FIRE Chief . . . NOT police chief.
As my Fire Chief admitted, locks have nothing to do with fire safety (purpose of these CMRs by law).
It becomes obvious that while we (gun owners) were watching the front door (actions by legislators, police chiefs), someone in the anti-gun movement snuck in the back door (State Fire Marshal) to pull a fast one on us while nobody was looking. [If one "studies" how/who gets to be a State Fire Marshal, you will realize that it is a POLITICAL appointment by the Governor and the person does NOT have to be a firefighter or really know a damn thing about fire fighting! I did some consulting for a person who held that position many years ago . . . he was also a Deputy Registrar of Motor Vehicles at one time . . . all political appointments because he was a rich entrepreneur and very well connected scumbag.]
In general the "original container" issue (per Fire Chief) is important for storage of all powders, as the containers are designed with a pressure "weak spot" to avoid exploding. "Original containers" do nothing for fire safety wrt cartridge storage.
After any loss, your insurance company can make it an issue (use it as an out to deny coverage) wrt improper storage of ammo, but indications that I've been given are that you will not be prosecuted for it (and knowing this, it is very UNlikely that the local fire chief will write that level of detail into his report, according to what I've been told). YMMV
