storage of powder and primers

[Raymond.Emsley]

I also understand that powder and primers needs to be separated with at least 3/4 inch plywood.
When it is in the same box or container.

If I was desperate for controlled temp storage of powder and primers, I would consider an old dead refridgerator. So long as the door seals and keeps out temperature fluctuations, I would think that that would be a good choice in a garage. Hasp and a padlock and it's locked. Shelves should hold a few pounds of powder.

Not the prettiest of solutions, but in a garage it should work.

why are people still building boxes? put a shelf in your reloading room and put the cans on the shelf.

That's my problem, my reloading rig is in the garage.

My first two years of reloading was done in my outside unheated shop. I had concerns but zero issues!

Everybody with a blasting licence that has a magazine in this province stores it all outside. Can it be that different?

Yes! I too...but under my bench. Just gotta keep the primers and powder separated.

An old welders trick was to put a single 24/7 light bulb (works better with a 'heating lamp bulb but is more costly to run) in an old fridge to store open boxes of welding rods in to keep the 'flux" dry...should work just as well for an unheated building reloading storage comp.

First thing to do is read the storage precautions on the powder container itself, which will answer most of your questions.

From SAAMI:

RECOMMENDATIONS FOR STORAGE OF SMOKELESS POWDER

Store in a cool, dry place.
Be sure the storage area selected is free from any possible sources of excess heat and is isolated from open flame, furnaces, hot water heaters, etc.
Do not store smokeless powder where it will be exposed to the sun’s rays.
Avoid storage in areas where mechanical or electrical equipment is in operation.
Restrict from the storage areas heat or sparks which may result from improper, defective or overloaded electrical circuits.
Do not store smokeless powder in the same area with solvents, flammable gasses or highly combustible materials.

Cold doesn't hurt smokeless powder but excessive heat does. Cooler is better. Keeping the powder at 15C or lower is a good idea. Heat and moisture are what you need to avoid.
