Headspace is set once and for all, by my gunsmith. I only unscrew the barrel by hand, and screw in the new one. In theory, I can bring one rifle and four barrels to the range, and switch barrels with no tools, as easily as switching muzzle devices.
Winter have been weird, and mild. I live in the south-eastern low-lands of Norway, 200 feet above sea level. We have 4 inches of snow, most of the winter we’ve had none. Usually, we have 2-3 feet. In the highlands, we have a lot! Like 12 feet. This winter, explosives have been necessary to clear the road on some mountain crossings.
