Storing Powder

[Metal God]

Wow I'm in trouble. What about limits on primers? They seem far more dangerous. Don't ask how I know.

Aren't we all especially with regards to primers . I'm sure there's a number , I think someone posted earlier 25k was max but I don't have any info on that either way .

I have a very small reloading room in the basement. It’s not suited for high volume, so I never have more than 10# on hand. Room is always around 70 degrees with low humidity. Powder is on a wood shelf with lots of space between original containers. Primers are on the opposite side of the room in a wooden box with three drawers. HVAC vent is outside the door, so room stays cool without the blowing effect of the vent.

I keep it in a, well, cool dry place. My basement in a locked metal cabinet (not a safe- just a flimsy home depot sheet metal cabinet. I don't keep too much around for financial and logistical reasons - I try to standardize on a small number of powders and primers. Typically 4 types or so of each does the job for me. Safety wise - I'm not all that concerned. I can't imagine what would set it off that wouldn't already mean I have a house on fire, and if it did go off in a fire, I doubt anyone would notice as I don't keep much on hand.

I don't keep my powder in the house but in a small wooden cabin about 20 ft away that is built of a 1" layer of Poplar covering a 1" layer of Oak. I keep a dehumidifier running year around and it stays at about 50% humidity.

But I don't worry in the least about fire even though we have a volunteer fire dept that won't show up for at least 20 to 30 minutes. In fact my house isn't insured, it is what you call self insured. It cannot burn, only the contents are at risk. It's one foot thick poured in place concrete walls and 10" thick poured concrete floors and 6" poured in place roof.

That's not a house , It's a bunker haha

Depends on your insurance company and what they tell you about smokeless powder.
As for laws on storage and container, etc. those apply to black powder usually, not smokeless.

I've found several on the requirements around storing smokeless powder. Both at the national level and at the state level.

This thread is a good read.

Wrong,many laws and regulations on SMOKELESS POWDER...Federal,State, and local.

This is the BOCA regulation:

. . . holds more powder than we, as private citizens, are allowed by Federal law to store at home (25 Ibs.).

There is no such law.

It's not the laws that matter so much in most places, it's NFPA. . . (and) SAAMI quotes NFPA in its powder storage recommendations

There it is.

Currently I have my powder stored in Flammable Safety Cabinets. That's the best that I could come up with.

It's not the best you could come up with, but might be the worst. A propellant magazine is designed protect the propellant from the heat of a fire (thick walls) and then to vent at very low internal pressure. Propellant needs pressure to burn efficiently; depriving it of pressure creates a "whoosh" instead of a "boom".

Your fire safety cabinet is designed to store liquid fuel that requires oxygen to burn, and specifically to contain the pressure of a fire so as to reduce ingress of oxygen to the fuel.

You're almost exactly wrong, and you've built a cabinet bomb.

Post the code and locations of such. i.e. penal code, health and safety, fire. So all can read them. Even the insurance regulations or local.

Come on. Do a google search.
NYS is actually more stringent than the NFPA.
