Yes, found it somewhat temperature sensitive.
I did all my load work at 70 degrees preparing for his Arizona deer loads. (Did the middle of the road)
Was thinking along the same lines as you as to what the temps might be.
I will say this though, he had no issues whacking his buck at 400 yds and the temp was about 50ish degrees when it happened.
Was using a CDS turret and stayed on track.
