I’m loading for my .308 and have the following “issues”. Using AA2520 and Varget, I’m within ~50 FPS of each other and getting groups around .6MOA. My concern is that AA2520 is not a temp stable as Varget and when I start competitions in the Virginia heat, I’ll have issues. Can someone point me to a chart or discussion on temp stability? Or tell me if I am making a mountain out of a molehill. I’ll give up the speed for safety. Thanks.
