Beside the POI change, why is this so important? And even then lets say 260 rem 2850 and 2925 fps at 600 meters it makes for a .8 moa change on my setup witch is about 4.8 inch. that is over a string of fire … not from shot to shot btw.. And I should change the load that perform for me because of that? My argument is that is more marketing than anything else. If you are not convinced of what I say there is a well known video of demonstration 800 yard F-class on YT often on this site too, where the shooter makes changes withing is shooting string of multiple clicks up and down…. temps sensitive powder?

I wouldn’t call 68 fps non-temp sensitive. Your not going to see numbers much higher from any powder.

I really would like to see the data for all temps. Then I could adjust the data to simulate where I’m shooting and the season. This would be a worthwhile consideration and would allow one to make a powder selection based on the best performing powder at various ambient temp.
Additionally one could consider the impact on chamber temp when shooting a string at those temps.

I do not care about impact. I do care about barrel tuning, so will stick to 4350.

Tibosresrex on Sniper 101 has been preaching that powder performance does not change in a liner fashion for over a decade.

Did you test the powder at 100 F. I have shot matches at 100 F not 140.
Since you said what I have belived that the velocity variations are not linear
with temp, the change in velocity per 1 degree temp are not accurate.
