Hey all, Thought I'd share a bit of interesting data from the other day. Temperature stability is often talked about with choosing powders and Varget is often touted as being really temperature stable. I decided to run a few rounds of my 600 yard service rifle load across the chronograph on a chilly ND afternoon last week. This load is 22.6 grains of Varget in Starline brass with an 80 grain Hornady ELD-M. I originally chrono'd this load on August 12th, 2018 in Moffit, ND when it was ~100 degrees ambient at 2719 fps. This same load chrono'd 2700 fps in -2 degrees ambient for a whopping loss of 19 fps or .69%. Pretty temperature stable if you ask me.
