Are there laws/ordinances regarding how much ammo one can store in their home? I've got about 5k rounds of various calibers in the house (I know that's probably nothing compared to some of you!) but even this modest amount would pose a danger if there were a fire or such in my home. Is there a legal, or more importantly, a common sense limit? Is there a best practice/location for storage? Right now I just have it all locked up in .50 cal ammo boxes next to my gun case. Is there a better or safer way?
