There is a real easy test for this, I have done it many times. Load 20 of your standard/go to loads and stick 10 of them in the fridge or freezer overnight. Then when you are ready to test them take the cold/frozen load to the range in a good cooler with ice to keep them cold/frozen. Then chrono both of them and you will have the answer. I like the Reloader powders but they are all temp sensitive as you will see. I have even done this with the Hodgdon Extreme powders and they are very stable. I will shortly be testing IMR8208 for a coyote load and US869 in a 7MM STW load to verify the claims by IMR/Hodgdon that they are temperature stable powders.
