Rifles were carefully cleaned of all lubrication and left outside ( we were in the company of a very good guide and native Alaskan.) I even managed to locate finnish ammunition for my rifle, their powder being famous for maintaining velocity in cold temperatures. In this case the primer was firmly dimpled. There is a point where extreme cold will inhibit detonation. My point, is that when a rifle won't go bang an even more fragile human body belongs inside <img src="images/graemlins/shocked.gif" alt="" /> I didn't need to look at the cabin thermometer. The sound of Spruce trees shattering was enough <img src="images/graemlins/grin.gif" alt="" />
