Smokeless Powder & Primer Storage (http://www.beartoothbullets.com/tech_notes/archive_tech_notes.htm/60)

Covers all the bases, Marshall -

Glad we have it so we can guide future questions to the Tech Note section and save lots of bandwidth.

Certainly very complete.
Have you looked up a Materials Safety Data Sheet (MSDS) on smokeless powder? I have never seen one,but I know that the manufaturer of a hazardus material has to provide one for each product.
This may give us a more concise explanation that is "Official".
I emailed Hodgdon for one,but I'm sure tht you could get a faster responce.

Thanks,Jack
I see that the 'Storage' section gives very little detail;it just refers to applicable codes.
