Moly lube

[greener]

I've been using moly lube (molybdenum disulfide) as a lubricant since last spring. Seems to have worked well until last Sunday. Temp was about 40F and the two Ruger MK's I had out shooting had a real bad case of slow bolt closure after loading a magazine. Seems like my lube didn't like the cooler weather.

Must be older guns, I don't work well in cold weather either.

bolt closing slowly?

Sounds like the lube you are using gets thicker when it's cold. I have never used moly lube. I have always used BreakFree CLP, and for me it works great.I do a lot of shooting in cold temperatures, my local club does not have a heated range, and during the winter bullseye league the temps get below 40 degrees at times. I would try cleaning the whole gun and lubing it with something else.

For a long time, folks who have to depend on their guns in cold weather (think Alaska, Arctic, Montana, etc, clean them very well, and use NO lube when it get really cold.
Even car manufacturers advise a lighter weight oil in cold weather.
A gross example, bacon grease is pretty solid even at room temp, but the more heat added, the thinner it gets.
On some guns, in critcal areas, I use 'Gun Slick' graphite lube, and wipe all visible lube off until I can just barely feel it on the part, or sometimes 'sili-Kroil' from Brownells. Kroil also works pretty well in getting out copper and lead fowling.
Just my opinion.
Also, I'm kind of like B&OM, I don't work so well in cold either anymore. For me it's mostly arthritis in my hands.

[Bullseye]

Typically around 40°f is where most guns have feeding issues with traditional lubricants. Less is better in cold weather. When the temps go up your usual amount of lubricant will work fine again.

I was referring to the temps in the range not outside.
