A few years back, two of us went on a winter cow moose hunt.70 miles in by sno-go we set the wall tent and wood stove.
After camp was set, we put dinner on the stove and tried to pour a nice sundowner but the Crown Royal wouldn't pour.....froze.
How cold was that?......damned cold. The next morning we harvested our cows and headed home with no thought to rifle
metallurgy.
