How cold temps affect your reload performance

[Nando]

I noticed last winter that my reloads didn’t behave the same once temps dropped. Velocities felt inconsistent and even my groups opened up a bit in the cold. It really hit me how much temp messes with how powder acts. Has cold weather messed with your reloads before?

Yes, cold weather exposed it for me too. Velocities dipped and it taught me to test loads in real winter temps, not just summer range days...
