Though I am curious, at the end of the day I think I'd rather have a load that I know will work consistently regardless of the season.
I asked Mas Ayoob about that in the self-defense forum. He said that my usual loading of my G17 (WW +p+ 115gr JHP @1400 FPS) would penetrate winter clothing just fine, but he noted that winter clothing material tends to fill the hollowpoint on most bullets, which is why he carries a .45. Well, if my JHP fills up with clothing material, it will act like a semi-wadcutter at 1400 FPS. I can go with that.
