(Installing second A/C unit directly in new loading room and man stuff storage facility, this spring. Right now, Brrrr!)

I meant, “No, I do not at this time”.
I keep mine in the house in the ac. I also return the powder to the bottle after my load tray is full. I most likely wont have the big swings some do, and was trying to keep all the stabilizer from off gassing. 4227 has the strongest solvent smell, I love it.
Bulk storage of powder is in a detached shop that I keep climate controlled with its own HVAC system. Besides keeping my powder dry, I keep the humidity at a level that prevents rust forming on my tools.
*Edit- Move powder to plastic before any signs of deterioration.
The new plastic containers should solve any problems. Any HDPE marked bottle in black should be ok to use. HDPE is on the bottom of some Hodgdon smokeless bottles i have. Black is to keep the sun off the powder. Transfer powder from metal cans to HDPE plastic.
The 2 other cans of IMR 4895 had no issues. But may have been a different lot number? Age?
The powder may well continue to deteriorate in its new quarters and could possibly start a fire.
Check it out carefully for proper appearance and smell before you repackage it into HDPE containers and put it back into storage.
Ya, that is one corroded can!
This, my stuff is stored in my safe room under my garage. It's on it's own zone for the geothermal system and in the summer I run a dehumidifier. I keep the room right at 50% as I've also got some pretty nice wood stocks, so I don't want to go to low.
Our coastal retirement location reaches 100% humidity during winter rain season.
All the powders are kept in factory original plastic containers and any powder remaining in the hopper is dumped back into containers.
Going on 7th year and no moisture issues.
I would guess, not fact, that the majority of issues come from leaving powder in the dispincer long term. The more difficult the dispenser to empty the bigger the issue.
No one I know uses desiccant in the powder hopper.
If humidity is a concern, once reloading session is done, unused powder in the hopper NEEDS to return to factory plastic container where it was intended for long-term storage.
You can consider running dehumidifier in the reloading area also but I do not recommend leaving powder in the hopper of a measure long term.
I see a lot ot cans in my line of work. Paint cans to be specific. 15 years ago, the cans were absolutely phenomenal at lasting forever. Nowadays, or pre-covid, cans would come in with rust on them. Seen them rust out in under a year. Yet cans we have from 1990 are still perfect, in a heated, but not air conditioned warehouse in the eastern KS heat and humidity. Its all about the steel quality.
Back before the 2015 shop fire, I kept my powder in a mini wine fridge at 55 to 60° in a heated but non air conditioned shop. I had plastic, metal, and cardboard containers in there. All were fine, and due to keeping it at the 55-60°F range, there was no condensation when removed unless the outside temps were near 100°.
