I was once told Re#22 and WXR are one and the same ? So RE powder are temp stable ? Can some one prove the Hodgens are ? What about RamShot ?
I have not found the extreme powders to be stable. I have done my own tests by placing ammo in the freezer and ammo in the oven at 110 degrees. I witnessed spreads of 130fps with the so called temperature in-sensitive powder. I also tried some of the temperature sensitive powders and witnessed about the same spread. From now on, I am gonna use the most accurate powder in a given chambering regardless of brand as I have seen no real benefit with Hodgdon Extreme. I would love to be proved wrong because before I performed the test, I used the extreme powders a lot. Viht high energy powders(N series) proved to be the most stable in my tests.
