Whats the best cold temp bolt lube ?

We had some sticky bolt issues in Wy last week. The temps got down in the teens or lower and we had some extremely stiff bolts. It was almost to the point where I thought I had head space issues or some debris was lodged in my throat. I could barely close the bolt. Both guns where using TM ultra grease, and very little. I would've never believed that a bolt could be that stiff. Any actual cold weather experience would be appreciated.

P.S. On a side note: I think when it's that cold and\or wet, it's good idea to dry fire your rifle to" potentially" break the firing pin free. That almost cost us an elk, even with a custom bolt. The firing pin didn't completely engage the primer and my buddy had to re-bolt, and thankfully the second time it fired. It was cold and snowy, with lots of moisture. I think it just froze up a little.

Thanks Brent

When it that cold grease pretty well goes to pot till it warms up again, A very thin oil works well though, like Rem oil, WD40. Or a dry lube, tungsten disulfide is some pretty interesting stuff

Re: Whats the best cold temp bolt lube ?

(I have converted this to Fahrenheit for you nice folks)

Depends just how cold it is. I live in Saskatchewan, Canada (no, I don't live in an igloo), and here we can get temperatures from 100-105 degrees in the summer to -40 or -50 in the winter.

For temperatures -10 or warmer, I coat the moving parts of my guns in light sewing machine oil, then wipe them off with an absorbent cloth, so there is nothing but residue left.

For colder temperatures, I don't really lubricate at all. Bolt action rifles are simple and tough, and they'll handle a lot of use with no lubrication. It won't be slick, but it WILL function. Such is the price you pay for cold weather hunting.

MOST IMPORTANT: Gun companies use heavy, dark, GREASE stuff in all the little crevices of their guns to make sure they don't rust while they're on the shelf. GET IT ALL OUT. This grease will positively cement your parts in place in cold weather, and there is no way to get it out while it's cold. If you can, take your bolt apart and get this grease off the firing pin and spring. If there is any of it on your firing pin at -30 or -40, your gun will become a very expensive club.

Go to a car parts dealer, and pick up some aerosol Brake Kleen- it's a solvent that removes oil and leaves no residue at all. Get a tub or something to catch the mess, and use the Brake Kleen to flush the nasty gunk out of your gun. Keep flushing until the liquid runs clear.

Please do this in a well ventilated area, wear gloves, and be careful about your stock, synthetic or wood, as Brake Kleen essentially eats oil, and it can also eat a lot of other things.

Not as effective as brake cleaner, but I use off the shelf carb cleaner just because it smells better, still seems to do the trick though. But an arisol can of brake cleaner gets everything out.

I think your right saskshooter about the " no grease "when its that cold. Good advice, probably take my bolt apart and remove the factory lube and clean it. Maybe use a lighter oil instead. I've never tried WD40...don't know why it wouldn't work. Have any of you guys ever used graphite lubricating powder?

OIL or NOTHING. Its not going to hurt that bolt to not cycle...or to cycle 2-3 shots while your out there... Of course as soon as you get to camp; home; wherever...you have to tear it down and "oil her up".
