[QUOTE="kcebcj, post: 858966, member: 10391"] All powder is temperature sensitive some more than others. I develop all my hunting stuff in the spring and fall like now when the temps are within 20 degrees of what I hunt in. Most of the loads developed like this usually end up a couple grains below what Quickload deems dangerous so if I shoot them when its warm I don't need to worry about having a problem and if they shoot a little off I understand why. One powder that I have fooled with that was pretty good whether hot or cold and accurate is H4831. Just could not get the velocity out of it that I was after. You also have to understand the consumer chronographs are not perfect. I use the Ced M2 and at times I just shrug and ignore the data. Your real fps will become evident when you prove the come ups and make the corrections in your ballistic program. Yes a temp swing can really mess with the load. Just letting the loads sit in the sun will have a impact. [/QUOTE]
