[QUOTE="Lefty7mmstw, post: 1113789, member: 48043"] I stay away from Hodgdon unless they are the only one with the burn rate I want. I've seen their temp stable powders drop the ball pretty badly... nearly as badly as (shiver) "ball" powders...I use retumbo and h4985 on occasion (I may even have some h4350 and h414 around) but I have 4 # or more Alliant to every# of Hodgdon I have. I think I have more IMR than Hodgdon too. Alliant walks in fps in a predictable fashion so if I find a load with any window at all I'm good. A load with a very narrow accuracy node will likely prove flaky with even a bit of atmospheric pressure change. I've gotten 150 fps spreads with h4895 between the cold and hot extremes in my 25wssm tossing 100 sierra pills. There are things other than the powder that can be unstable when the temp. changes. You have to test your system and not follow blindly. [/QUOTE]
