I wouldn't worry about special storage. Just put the cap on and keep from getting extremely hot and it should be good for 50 years or more. I'm still using some WWII surplus powder.

Noted.

How does powder like the changing temperatures and cold though? It's never usually humid, or hot up where I live, but my reloading room drops to freezing occasionally during winter nights and during the day it'll get up to 74 as I open the door to the room and let the stove keep it at a comfortable temp.

keep dry and not to hot will last 50 years or more do not over think it

I just finished a 35 or so year old can of HP-38 about a month ago. I bought it new and loaded some .38spl with it, then moved on to other calibers and powders. Its been sitting on the shelf half used in its original container for 35 or so years. Decided to try it on .45ACP and finished the can up, it all went bang. As long as the powder does not smell acidic or bad, its fine to use and no special storage is needed for such a short time of a few decades.

"keep in a temperature stable room" is key here. Do that, and you're good for a long time. Long time.

In the original containers in a cardboard box under your bed.

Alright thanks for the replies guys. Time to store my H50BMG for eternity

Freezing isn't particularly cold. 80 degrees isn't particularly hot. Just don't put it in the attic during the summer (130+ degrees) or leave it outside in northern Canada during winter and you should be good.

I keep my powder and the original container, but it's in the garage, where I live I get temperature changes from a little bit below freezing to a hundred plus degree weather. The powder I have here is about 10 years old and so far no issues with it.

Pretty much, except mine is in my closet.

Ice chests. I store mine in ice chests.

I haven't done it with powder, but I've done it with paint cans. Stretch some saran wrap over the mouth then screw the lid on.

I wouldn't keep any powder, or primers, or any of my reloading gear, in a place where the temperature varies so much. Even if those temperature swngs won't kill the stuff.

On a related note, I recently loaded up some 40+ years old small rifle primers stored in a bedroom closet with no special care. All 100 went bang.
