[QUOTE="Wedgy, post: 1471532, member: 64108"] This is only my experience from out West where it gets over 100F for a couple months and rarely gets below freezing. I see very little rise in velocity with temperature, usually 0.5 to 1.0 fps per degree F from ~50F until about 84F, then the velocity will start to pick up much more per degree of F increase, some up to 2 fps per degree. At that point it is not a powder I can use because if I test it at the higher temp it loses so much velocity at the lower temp it's not in the node I tuned for. It can easily be close to freezing in the morning and near 100F during the day, very low humidity but I don't think that affects the burn inside the case. For me Reloder 26, 33 have shown huge increases over ~84F and I have had very good success with H4350, Varget, H1000, & Retumbo, As well as N570 but I can't find it anymore. Again, I only have to deal with the upper ends of the temperature swings.....hot flashed if you will. [/QUOTE]
