The "hot to cold" isn't an issue with the powder, it is an issue with the primers ensuring consistent ignition in deep winter conditions. That is the reason for "milspec" primers using a "magnum" primer charge even for standards rounds.

Lots of old wives tales about powder. But the military will continue to use ball powder because it gives the required performance cheaper than extruded, that is the only reason.
