When weather ruined my zeros

I zeroed my rifle in 70-degree weather, hunted in 20-degree cold and my point of impact shifted four inches. I didn't know temperature affects zero that much, so I missed my shot and learned an expensive lesson. I now verify zero in conditions similar to when I'll actually be using the gun..
 
My rifle was once fine in the summer but it started shooting low later in the season. So I always double-check my zero when it gets cold now
 
The first time I shot in cold weather, my zero shifted more than I expected. Since then, I always double-check it before the season, instead of trusting months-old settings.

Four inches off? That hurts. I always zero my gun the morning I shoot, even if I checked it last week. Weather changes, brass shrinks,and somehow life always interferes.
