I've burned a lot of 231 in sub freezing (and some in sub 0) temperatures and I've never experienced anything like that. I've never even noticed any loss in power.

I'm not sure why Speer shows such a hot load, but according to the Hodgdon reloading data center, a 158-gr. lead bullet (plated data is interchangeable with lead data), shows a minimum load of 3.1 grains of WW 231 and a maximum load of 3.7 grains.

The minimum load for a jacketed bullet (Hornady XTP in their data) shows a minimum load of 3.8 grains.
