Always remember the following: "He who worries before it is necessary, worries more than is necessary." I say this, because you really need to be careful who you tell about your ammo (and etc.), especially when dealing with civil servants whose job is to protect the masses, but who too often overreact in the name of public safety.
A few years back, while living in an appartment in a large city, I purchased some re-loading supplies. The outside of the box had "Caution: Bullet Components" written on it. When the package arrived, I wasn't home and the Apt. Mgt. office signed for it. When they saw the "Caution" statement, they promply reported me. I then had to explain to LE that no reloading was done on site (it was done 100+ miles away in a rural area). Although, I was not arrested, I was certainly intimidated, and it was an experience I would not want to go through again.
Just as I couldn't have known the reaction to the "Caution" statement, you could not have know the reaction of the Chief.
The moral of the story--be discrete, or be sorry.
