My hunting partner talked about temperature sensitivity . I said why bother, we work up loads at the range, it never seems to be more than 15 C in the mountains where the range is and we hunt at 5-10 C.. So I have and use plain IMR 4350 and IMR 4064. But it has caused me problems. When I was working up loads for my 264WM, RL-25 with each round of a 3 shot string would increase velocity, normally I would expect a decrease. It didn't go to waste, it works fine in the 6.5-06.
