Is it ok to store powder in pelican cases. I want to store about 20 lbs of my stock outside and pelican cases are weather tite

thanks

If the cannister lids are tight, the pelican cases aren't going to add anything. But then it won't hurt anything either. Heat and moisture are powder's enemy. Avoid both and you're fine.

Powder is supposed to be stored in enclosures that will let hot, expanding gasses to escape before the pressure becomes explosive. Pelican cases are unsuitable for that purpose.

OTOH, you are storing that stuff outside. It is possible the chance of fire is reduced, possibly to near-if-not zero. Even the chance of explosion during a fire might not mean much depending on what "outside" is like.

Those are the parameters. Yours is the decision.

Sure but seems expensive. Get a cheap plastic cooler. Put dessic bags in it & your set, just dont leave it in the sun..

I'm no expert, but I'd guess that being kept in a temp and humidity controlled environment is the key to powder storage... OUTSIDE might not fit that 'controlled environment' in my humble opinion. Hopefully some of our more knowledgeable members can help us out here.

Keep it in a dry, cool place with the lids on tight and you will be fine.

Build a wooden box to store your powder. There are many plans for them on the Net.

Store powder in cool dry places . Heat is not good for powder.
Outdoor storage buildings are not the best places because of the high summer heat and low winter freezing temperatures .

A long time ago I built a wooden (3/4 inch plywood) storage unit to hold all my reloading powders and primers. It has a locking door too. I keep it in my basement where the year round temps are about 65-70 degrees. Some of my powders and primers are years old but they shoot like as new.

The purpose of the wooden storage is wood is much slower to transfer heat than metal, better insulator. Yes, it will eventually burn through, but long after a metal container would have set the powder off.

All in all, once the house burns to the ground, it makes little difference how you stored your powder. Tight lid anywhere inside a climate-controlled house is fine.

I store my powder in a modified used refrigerator. The locking mechanism has been removed and replaced with a simple magnet arrangement. If there was ignition, the door would not allow any pressure to build. Running at the lowest setting keeps the humidity down as well as the temperature. I picked one up from an appliance company that removes old refrigerators when they sell and deliver a new one. What I got cost me $20.00 and works great. I have done this at least 5 other times.

A good container can take care of keeping out the humidity, but you also need to keep the powder relatively cool all the time. Temperature fluctuations are bad. If inside is absolutely not possible, I recommend burying the powder in waterproof containers. Even 3 feet underground is quite stable temperature wise. Plus, there's no risk of fire or explosion.
