[QUOTE="bigngreen, post: 411377, member: 13632"] H4350 and Retumbo are, as you know, in the same line of powder formulated to be extremely temp stable. So you should be able to have some expectations from the fact that both are formulated to handle temp swings the same. Temp swings are extremely important for long range hunting, I have used H4350 over IMR4350 in my WSM because of the possibilty of temp stability problems over groups for hunting and predicting first round hits on game animals. Both shot well and held to hunting standards to my effective range but I can have a 45-50 degree temp swing in one hunting day so having a powder change POI on me mid day is unacceptable even though I can take it into account with my ballistics program, I choose not to. In the end I found Retumbo out performed H4350 in velocity so that is my powder of choice for my main hunting rifle. I admit that I did not take the time to check exactly how much change I had due to temp with IMR powders or IMR4350 but I have shot enough of the Extreme powders to know that I have not experience any of the temp problem with the line. Conclusive, NO. [/QUOTE]
