I have a wood stove in the shop, so when I have a few hours, I fire it up and sit at the bench. I'm in the Midwest, so it gets into the teens and twenties her pretty regular through this part of the year. Oddly enough, there's no grass to mow, not much outside work to consume time, so I find I do more loading and shooting this time of year.
I'd rather have to put on an extra sweatshirt under my Carhartt than sweat my can off trying to test a load or chrono a new load.
Happy New Year to all.
