[QUOTE="morcey2, post: 950868, member: 71004"] I can't speak directly to IMR4350, but IMR4064 is my go-to powder in most of the chamberings I load for and it's somewhat temperature sensitive. I also use a lot of H4350 and it's been extremely stable (pun intended). Here's a page that Hodgdon did comparing some of the Extreme powders with IMR, AA, some Reloder stuff, a little Winchester, etc of the same burn ranges: [URL]http://www.hodgdon.com/smokeless/extreme/page2.php[/URL] Raw-er data: [URL]http://www.hodgdon.com/smokeless/extreme/page3.php[/URL] Since Hodgdon distributes both IMR and Winchester powders, I don't think they'd have any reason to fudge the numbers on those powders to make them look worse compared to the Hodgdon offerings. One of the interesting things I found in their raw numbers is that they found AA4350 to be inversely-temperature sensitive. Higher pressure and velocities at 0* than at 70* and the lowest was at 125*. I've picked up some AA-4350 to replace the non-existent H4350 in some newer loads. I'll hopefully have some better numbers on my own in the next month or so. If there is no significant difference between the temperature at which you work up loads and the temp at which you hunt, I don't think you have a whole lot to worry about. Matt [/QUOTE]
