This is a subject I know very welll, indeed....
Ammo can shrink, in the deep cold, enough to get light strikes, and delayed ignition "hang fires" of a second or more. Ammo using rims has a much better ignition rate in deep cold as the cartridge is held to by the rim, rather than the shoulders, as overall length isnt so important to rimmed cartridges...
Ammo will freeze to your fingers instantly too....
Plastic/synthetic stocks break easier.
Scopes fog inside and get drops of condensation, as well, your breath is a big factor on the outside of the lenses. Leupolds are the only 'old' scopes I see around here. Iron sights do so much better in deep cold
Stocks freeze to your face, and hands ( another reason for wood), as well as stocks warp sometimes when subject to -20 and lower
Thick gloves and mittens make for a hard to get to trigger....
Springs stiffen, and hi-cap mags need a few less bullets for better lift reliability.
The deep cold makes 'mirage's' and that makes sighting a pain sometimes....
Guns brought into a warm house will have condensation almost immediatly, and needs to be taken care of, no different than dropping a rifle in a river, you must disassemble and clean and dry. If you decide to go back out, and its not dryed, it will freeze, somewhere in your mechenisim......at the least, it will rust where you cant see. Greasing the metal under the wood is always a great idea.....
Lube solidifys , so we clean, lube and wipe clean. Real cleaning and greasing happens indoors, for storage. Graphite or 2stroke (snowgo oil) engine oil with TCW3 is the best, as it wont congeal untilll -120.......wipe any oils from any place you may touch.....-40 lube on your hands is just like water at that temp, itll get ya, ruin yer gloves, etc.......
There is a solution, developed in Arctic Country's
But a Finn M-39 has a rimmed cartridge, an easily adjustable firing pin, a wood stock that protects the hands from the barrel , burning or freezing your hands, a cleaning rod for snow in the muzzle and a shorter stock, because you will be wearing way more clothes than Fall time, and a side mounted sling for better carry, excellent sights and a large trigger guard......... True, but ~~LOL!!~~
