I grew up and spent most of my life in norther IL where it gets cold in the winter. The way I was taught to deal with cold was to wash out all the oil when I am going to hunt I normally use alcohol for this then I use powdered graphite to lube all the moving parts. I have hunted in below 0 weather a large number of times and never had any problem.
I also think the loading processes described in the article sounds like a beginner.
