Barrel Life and Cold Temps

Maybe a dumb question, but figured it could be a good topic of discussion!

A coworker and I were talking about going out and doing some target shooting in the local State Forests that are open for it once firearm season comes to an end around where we’re at (central MN), as I, myself, am not opposed to getting outside and continuing to do some shooting when the temps start dropping, to an extent (not trying to go out and freeze my butt off when it’s -40f).

He brought up that he’d be up for going and joining me come Spring when temps start to come back up, as he won’t do any outdoor shooting when the temps fall below freezing as it’s hard on the guns, specifically the barrels, do go from dead cold, to hot, and then the rapid cooling off the cold temps around here bring.

I don’t know. I see where he’s coming from, and can get behind the science of it, but I just don’t know that it’s that big of a deal. I’m also no expert in firearms, or metallurgy, but the tinfoil hat side of me figures if my firearm can’t function for half the year because it’s too cold and will just break from using it, then maybe it’s not that reliable of weapon.

Now, for some context, my AR is just a basic PSA upper kit with the Freedom Barrel, and not the nicer FN barrels or anything, so maybe there’s some weight to the argument, but one would think it this was THAT big of a deal, then half the worlds militaries weapons would be useless for half the year as well.

The other half of me also thinks, my rifle build came in at only about $450, so I’m also not that concerned about treating it like it’s some gucci gun that can’t see the slightest bit of abuse because I have too much invested in it. I also have my own threshold of what I’m willing to go out and tolerate as far as cold goes, and likely wouldn’t be out if temps are below 0-10f, but I do have interest in testing the tools I do have, to see how well they’ll actually hold up, in the, hopefully unlikely, event I’d ever need to rely on them to protect myself/family, regardless of what the weather is doing! Not that I’m ever just out and about with a rifle strapped to my back anyways, but I would assume all the same logic could apply to handguns, as well!

What do you guys think? Do you have your own temperature threshold you’re willing to go out and shoot in? Is it because of reliability/shortening of lifetime of components concern, or more just personal “I don’t want to be cold, it doesn’t sound fun” reasons? Do you have weapons you’re willing to subject to more “adverse” conditions over others?

sorry for the novel lol

If i had a precision bolt rifle, maybe. With my AR? Not worried about it.

The biggest issue will be moisture and or snow getting inside the action/chamber, and inside the barrel. I wouldn’t be concerned with driving out somewhere in the forest to shoot the ar, it’s in your warm enough car/truck/van whatever, then you step out into the cold and let’s say it’s a 23 degree day. As long as the rifle is lubed, you’ll be fine to start blasting. When I’m out shooting in the warm temps, about every 400/500 rounds I pull the bolt and re-lube the gun. Dirty guns function just as reliably as a clean gun, the issue is burning off all the oil/grease whatever you use. Dirty lubed guns will continue to function, bang after bang if you care enough to lube it up, it’ll perform for you. I’m in the North East, upper part of WV. Our usual winter temps hover around 20/30 degree dead of winter. I have no issue with using oil, in fact all I use is G96. Smells wonderful, and isn’t toxic. I’ve never had anything rust, and other than the normal metal wear you’d expect with metal on metal and high pressures contained within a firearm, I couldn’t be happier with it’s ability to CLP everything for me. I would be sure to run a bore snake through the rifle once I got back home, normal clean for it and I can’t foresee any issues, especially using good quality ammunition. I could see steel cased having some hiccups with metal mags in the cold, buy maybe not? I don’t shoot in anything colder than 0 at the absolute most. Maybe bring some gun grease with you as well, just to see how things perform in those temps.

I wouldn’t care at all. I’ll blast mine all day in cold or snow. Do Army’s in cold and snow conditions care? Nope. Do their guns fall apart and warp? Nope. Do they let loose in semi and full auto in the snow? Yep. Do hunters in Alaska use expensive hunting rifles in the snow? Yep.

Blasting tons of rounds in cold military rifles and just 1 or 2 in cold bolt action rifles literally happens every day on planet earth. So I’m blasting like Yosemite Sam.

Stop using your body thats full of water and blood as a gauge to predict some imaginary scenario in a metal object. Cars fire thousands of explosions in their cylinders in the snow. Planes fly in the snow. Metal is metal, it can survive hot and cold.

I’m sure many will disagree and thats fine. Stay home, drink hot chocolate, I’ll be outside blasting and living life and my guns will be just fine. If they explode or fall apart, I’ll admit I was wrong and buy more and keep blasting. Until then have fun and just go do what you do. Blast away.

Ummm, planes fly e’rday -65 outside that window seat while you’re comfortable just inches away. I’ve bagged a deer from the monkey boards on a drilling rig in zero/sub-zero conditions, so have a few of my friends back in the day. 70 to 100 feet in the air made an excellent view. My how times and rules have changed.

My only care would be in bringing a cold gun into a warm house may cause condensation on the gun.

No, I never have an issue with shooting during the cold months. It takes a lot more temperature variance to effect steel and I don’t think cold temps effect lubrication but a little extra lube won’t hurt before going out to the range.

This is pretty much what my exact thoughts on the matter are, as well. Surely, if a car can survive just fine in the dead of winter with wind chill occasionally getting as low as -60, then why would a firearm be any different.

The hammer in my garage doesn’t explode into a million pieces during the winter if I hit it with a nail.

Don’t get me wrong, I have nothing against anyone who opts to put the brakes on shooting activities during the winter for whatever reason they choose! To each their own!

Yup, my gun my choice, their gun their choice.

I like training in the winter and sometimes in rain and snow cuz stuff doesn’t always hit the fan on nice sunny days and I want to know what to expect from my gear if it hits the fan on a bad hair day.

My Pop told me stories of the Actions Freezing on the M-1 Garand in -30 below Zero weather in Korea in 1950-51 …they even had to kick them open after Running a Zippo Lighter over them , covered by a poncho to not give away their position as easily.

The M-16 has been tested in Cold weather going back to Stoners first attempts to sell them to the Army in the late 50’s…I’ve had mine at -10F and experienced No problems at any level.

I understand the hesitation without Chrome Lining… but you need to know that thing is going to work year round in the conditions where you live. You cant always pick the conditions a weapon might be called upon .

I go out in the winter and shoot, never really thought about it loke that tho. Most hunting is done in the winter.

That’s a very fair point! I’ve never done much hunting, aside from a little bit of grouse hunting when I was a kid, but it does make sense. Hunting season is always right around the same time things start freezing around here!

Deer really start movin.
Rut season tho, almost hit a buck chasing a doe the other day. Didnt even look up at me, just sniffin that love.

“Surely, if a car can survive just fine in the dead of winter with wind chill occasionally getting as low as -60, then why would a firearm be any different.”

This be an engine block heater. Wonder what is used for?
Sorry, had to do it. Opportunity and the old “I have a hammer, everything is a nail” meme was just too good to pass up.

Folks; just remove that overpriced canola or Crisco shortening you grease your tool with. Should clean the gun and use low temperature rated lubricants or no lube at all. Don’t be a German on the ruins of Stalingrad with a frozen gun.
You are going to have to remove the condensation once you bring the gun inside, so yeah, Inspect and lube after every trip outside. Ask anyone who stood in the middle of a Louisiana swamp during duck season.

Entirely off topic and I know you’re not really asking, but this one in particular is for the Ford 6.0 liter diesel -quite the life saver when temperatures plummet. That said, I’d never use a barrel heater on my firearm. :ghost:

To answer the OP:

No threshold for me. Whenever shootin’ needs done, shootin’ gets done.
