The last thing you want to do is call any kind of official and tell them you have x pounds of potential bomb making material in your house.
I tend to agree with Joe 6-pack.
People really need to think about what they’re doing before they store 80,000 rounds of ammo at the house...
...prepositioning it in multiple, off-site, secure caches is a better plan and offers a lot more flexibility.

Especially not the ATF!
Just got a call back from my local fire marshall. In the 2003 International Fire Code, CHAPTER 33 EXPLOSIVES AND FIREWORKS, Section 3306 - Small Arms Ammunition; there is a restriction limiting you to 10,000 primers, 20 lbs of black powder and 50 lbs of smokeless powder.
