43.2 gn RL-15 and a GM Match primer, All rounds leave at 2640 to 2648 FPS.
So 43.2 gr of Reloder 15, gives you precisely the same mv all the time, regardless of temperature?

I tried it in 54R and .308 loads, and went back to Varget due to what I perceived was temp sensitivity, and found a lot of other similar findings online...
