I've much less experience with it than others, but I'd say it is very similar acting to Varget and H4350 with regards to temp sensitivity...that is to say, a *little* but not very much at all.
I don't know about other applications but in 223 I found a 36 fps difference from mid 20"s to almost 100 degrees in my 75/77 loading.
My crony isn't the best but my come ups jive'd with a air density only change.
Wish I could say the same with my beloved W748.
