Staball 6.5 and staball H.D.

As previously noted, I used to be Hodgdon extreme powder (https://hodgdonpowderco.com/wp-cont...est-results-for-temperature-sensitivity-1.pdf) user only. What you seek has been their selling point for many years, and it still does. They supposedly tested them for the 0-125 degree temperature range. Good luck!

This is beauty of it all, you can have plenty personal choices to choose from.
Looks like I need to start getting some H4350

As noted, I still use Hodgdon Extreme Powders. My records shows (10/2014) I am getting 100 FPS more with RL-17 over H4350 with Berger 215 in my .300 WSM. So, it has almost 10 years of longitudinal use. And no, I am in no way endorsing it, but simply saying I made it work for my intended use.

I am currently using H1000 and Retumbo in my pressure testing in my .257 WBY and 163 Chinchaga. Good luck!
