I think the SAAMI prefered method is a wood storage box with at least 1" thick walls. My loading bench is supported on a "lower Kitchen Cabinet" type box that is double thickness wood. It has a locking cabinet door. The door is "weak" so that it would vent. Actually a good yank would pull it off the hinges. Anyhow it will store at least 50 lbs powder. Primers are in a separate cabinet.

SAAMI states you can keep up to 50 lbs at home. However, your homeowners insurance and even your local Fire Marshall may say otherwise.

I would think that an NON OPERATING fridge would be an excellent storage container as long as it did not have the OLD STYLE locking latch. Friction doors on any fridge made since about 1965 would be ideal. It's insulated, doesn't easily burn and has a weak venting friction door. I wouldn't use a operating fridge as there would be moisture issues.

Sorry, don't know anything about Cabela's metal boxes. If it's for powder storage, Cabela's wouldn't sell it if it didn't meet SAAMI standards.
