Best powder for LR 300 win mag

How is your temperature stability with R26? I have been tempted to try it but I have heard mixed reviews. I have been using Retumbo which gives about +100FPS velocity over H1000 in my 300WM and has excellent temperature stability from sub freezing to 75F which I encounter during hunting season.

It's rock solid 17° - 70° in the WSM from what I've tested. It changed 7 fps across 53°. I'm going to run some through WM to see what it does there.
 
Up, because Norma, Ramshot, and Accurate are no hazmat at Midway with code Augustpowder. Good shooting...stay safe. CWF
