Been here a long time but seldom ever post but this time I couldn't resist. 6MM obviously hasn't been in North Dakota in the winter either. If you couldn't shoot a rifle at 40 below you'd have to pack them away until spring. This is only partly being a wise ass (smile). I will admit to having fired a rifle at those temps and it didn't explode and the bullet exited the barrel. But then I've only lived here 73 years and don't know what others experiences might have been.
