Reloading and Storing Powder In Unheated Garage?

But more of temperature change and the resulting changes in humidity. I'd be more concerned about freezing to the chair. How cold does it get there?

I've stored powder in an unheated building for more than twenty years (some of the powder is that old too) and have never had a problem. This is with the old metal IMR cans and the cardboard type Winchester containers. The newer style plastic ones I also store that way, but for not as long of course. As far as I can tell, as long as it's kept dry and out of direct sunlight, it's not affected at all. I think heat would be more damaging by far.
Our temps get well below -40.

Same here and some of my powder has to be 40 years old. Primers are out there also and have been for years. Have no choice and no problems to speak of so far
Cheers
 
Temp. changes could cause condensation in the can. I know I can feel the condensation on my tools and you can actually see the beads of water

Not very cold at all. Next to the weather on the west coast, I believe Creston is as mild as it gets in BC. I was more worried about moisture content in the air than frigid temperatures ruining my powder.

All my powders are in their original plastic containers. I think I don't have anything to worry about. Maybe I was over thinking after I was questioned about my storage choices, but it never hurts to look into what may be a potential problem.

The powder is out there, but not as easy to obtain when you need something specific. I don't want to waste any over a problem that I didn't see coming.

Due to space issues, I reload in my unheated garage. I figure this is fine in the summer, but I'm looking for any thoughts and/or advice for storage and doing this in the winter.

Will the moisture content in the air adversely effect my powder during the cold winter months?

Cheers all

My powder is in the basement and has minor temperature swings. IIRC temperature fluctuations are the thing to avoid. Go ahead and reload in the garage, but do you have a crawlspace or basement where you can store your powder? Another option would be to store powder offsite (parent's or brother's basement etc.) and keep small, quickly used up quantities in the carhole.
 
I had a problem with bad skeet loads from storing them over winter in my shed which is heated with wood stove. Store them in house from then on. Condensations was culprit, every time I put wood stove on.

If necessary, I could build myself a locking cabinet and just store it a closet in the house. I'm ok with where it is now.
 
if your going to keep it in the garage you could insulate your cabinet with styrofoam and then I would paint the styrofoam to keep the chances of static down . if that's too much of a hassle get a coleman cooler and store your powder in it .
