[QUOTE="nicholasjohn, post: 1645880, member: 109113"] I think you'll find that what delivers the best SD & ES in one rifle/cartridge combination may [I]or may not[/I] be the best in that regard in another. There are so many variables in the equation that each one is different. If you bought two consecutively numbered production rifles, in the same chambering, barrel length, etc., you could developed a load for one that was absolutely perfect, and it wouldn't surprise me one bit if it didn't perform worth a **** in the other. I think it's best to look at the things that are known to contribute to delivering good SD & ES and make that your starting point. If there's a shortcut to finding the best formula, I'd sure like to know about it. I don't think there is a way to know for sure. I do know that I have had best results with a powder that most nearly fills the case. As far as the temperature sensitivity issue goes, most of the guys on this forum ( and others ) seem to be finding that the Hodgdon Extreme line of powders takes the trophy in that arena. I have found this to be true, as well. The table somebody posted here in answer to your question bears this out. I noticed that the old H-4831 showed more temperature sensitivity than the H-4831SC. It must be that the old version doesn't employ the same technology as the short-cut version. [/QUOTE]
