It should perform about like BreakFree CLP in the cold. They both use the same synthetic oil as a base unless one or the other has been reformulated.Mobile 1 thickens at a much colder temperature than regular oils. I would suspect if you lube your weapons with it you won't have to worry about the cold.
Can't agree. Pull your gun out of the truck and by the time you tromp through the snow to your blind it is damp. Haven't seen much dry cold air up here. Maybe snow in KS is dry but ours is wet and a wet cold Michigan day makes for horrid hunting conditions, unless you know how to dress. The humidity up here is different then where you are for sure as we are surrounded by water on three sides of this state. Michigan has the second most cost line in the United states with Alaska being number 1. Michigan is hummid all four seasons up here.
ai&p tactical said:I would recommend he consider the ammo he was using may have gotten damp because it was taken from a heated auto or Cabin right out in to the cold.
Don't know about the UP as I am in the middle of the state about 8 miles inland from lake Michigan. Winter humidity can be high as in 90's to a low in the upper 60's depending on what systems come through. Anyone can verify this on any weather site. Seldom if every do we have dry air. The lakes are wet and snow is wet.

+1 This!The thermal coefficient of expansion for carbon steel is 7.3 x 10 to the minus 6 power inches per inch/degree F. 400 Stainless is about 4.5 x 10 to the minus 6 inches per inch/degree F. That ain't the problem.
And that!I have never heard of an 870 freezing in my life.
I use Mobil-1 0W-40 in my car. Yes, there is such a thing as a "0W" oil It ought to flow very well at low temperatures.I use Mobile 1 synthetic on all my firearms. Mobile 1 thickens at a much colder temperature than regular oils. I would suspect if you lube your weapons with it you won't have to worry about the cold.
Same issue the Germans had after invading the Soviet Union. the weapons failed and the lube gunked up. MP40 held strong due to fixed firing pin and bolt slamming forward and could be run with minimal to no lube. Soviet weapons fared far better.Many firearms will freeze up at that temp; there are tons of Korean war tales of Garands, 1911's and Carbines freezing during engagements; in some cases they were urinated on to unlock their actions. All of these have longer firing pins than the hammer guns do so that explanation makes sense, especially if the oil on the firing pin and hammer area freezes up.
My South Dakota buddies use dry lube on their bolt guns, as these will also freeze shut on them.
