Hodgen Extreme Powders ?

What I wonder if IMR 4350, R25,R33,IMR 7828,Retumbo, H1000 & does temp sensitive relay matter, since final sight in my rifle is in the Fall right before going hunting. Temps when sighting in 40's & temp when hunting 35-10 F, most of the time.
So we are talking 30 degrees spread average. Has anyone tested for temp changes ?
