Temperature stable powders.

Which powders have you used that show the least variation in velocity when exposed to extreme temperature fluctuations?

I've read Varget and 8208XBR are supposed to be good in this realm, but have not tested them out for velocity fluctuations personally.

Any others that would fall into this category?

The F/class crowd likes Varget. With judicial loading parctices they are getting their SD down to 3-5, which is phenominal. I shudder to say this because it's getting harder and harder to find.

The Hodgdon Extreme line does very well. I have used them as my match powders shooting around the country in different temps from the teens to over 100 and they never let me down. Varget, H4350, H1000 stc are excellent.

Stay away from Alliant rifle powders.

H4895 I have had good luck with it in 308 and mixed success in 223.
