Heat was not an issue, nor were significant temperature swings. Although I read a little about temperature sensitive powders, I really don't understand the specific impacts of temperature fluctuations or how much of a fluctuation is required to see changes in performance or safety. Now that we're back in the southland, I thought I'd pose a question or two. I'm hoping some folks with real world experience will share some thoughts and experiences. CFE seems to be the most popular powder mentioned when discussing temperature sensitivity and I have a few loads with CFE that do pretty well for me.
How high does the temperature have to hit before you see changes? Is there an actual top end, or is the issue more of a significant change in temperature? Are there other environmental considerations, such as humidity, that also need to be considered from a pressure / safety standpoint? How do you monitor changes? Is it all trial and error while tracking environmental conditions and load performance? What else should be considered?
I can say, I won't likely be in any 100 plus degree temps shooting, but I may be out in the 90's. We may bump into some humidity as well. Any thoughts or wisdom would be greatly appreciated.
