A quick, short term solution is to get a big cooler and just put the powder inside. Fill any open airspace with bottles of water to get some thermal mass inside the cooler. That alone will slow down the temperature swings.I no longer have climate controlled outdoor storage for my powder (15lbs), no prospect for regaining it, and am not willing to store it inside my home.
Would loading the powder and keeping ammo outdoors be better, worse, or no difference?
Unairconditioned garden shed only option.
A small refrigerator is the next option. Turn the thermostat inside it to a reasonable temperature (60-70 degrees?) and it won't run very often. You can probably pick up a dorm room sized fridge for cheap right now.
Make sure there is venting in the shed to allow the hot air out the top and cool air in from the bottom.
