My gum powder is stored in a dry environment. But where I live gets -20° Below. Do you see in any way where this could harm gun powder? Never had a problem with it before but just got me wondering. Thank you in advance for your opinion.

Nope heat is what kills powder.

I keep mine inside the house in an unheated room.
it doesn't get negative 20 in there, but it don't break 60-65 in the summer.

Heat and humidity kill smokeless powder.
I still use powder from WWI that is as good as it was made in 1917.

And its 10-20% humidity

How about storing powder in a domestic chest freezer ?
Would that cause any deterioration over time or affect the powders qualities in any way ?

what heat temp. is bad to store rifle powder.? just asking

My general rule is below 90 F is desirable. Low humidity.

-20 below does strange things to anything, I would not store powder or much of anything at that temp, and don't thaw it out in the microwave!

Two things are wrong with that idea. First, powder should not be stored in a container which confines it such that it could explode with force if ignited. Second, condensation tends to form on anything inside a freezer which would contaminate the powder.

Just store it somewhere in your house or a heated work shop is best thats where mine is and idaho gets real cold at times..Changes in temp is hard on powder, some powders are better than others in stored conditions...Keep your powder dry has been a saying for a multitude of years and keep it in a "cool dry place" on the warm side of cool!

Like StoneCreek, I'm not a fan of condensation in any fuel.

Any moisture in the powder, even from factory, will magically appear out of the powder when stored below freezing and brought up to ambient to quickly. I don't know if tempering would make much of a difference.

Wish the R&D guys from Hercules Kenville were still alive to ask these questions. Hercules and others made powder and dynamite in some of the most humid states year round.
