In another thread a few people mentioned using old refrigerators to store powder to help fight humidity. I was wondering if those old fridges make suitable powder magazines. Now, I understand there's no need to keep smokeless powder in a magazine because it's not explosive, but eventually I'll load black powder and will want to keep it all in the same place. Will storing black powder in a fridge turn it into a potential bomb, or is the seal on the door weak enough that it's not an issue? Maybe the hole you have to drill for the power cord for the dehumidifier is enough to make it safe?
Which brings me another question. Is there anything wrong with having an electric dehumidifier in a powder magazine with black powder? My gut tells me it's not a good idea, but I don't have any actual experience with gun powder beyond shooting.
