Oil for locks?

[Jim Chambers]

I am so glad you guys are using something (anything) to lubricate your locks.  You wouldn't believe how many locks are sent back to me because they won't work, and the ONLY thing wrong with them is a complete lack of any lubrication at all.  I got one back just last week.  A little lubrication applied to the working parts made it work perfectly.
I used to use and sell the Accuaguard and Accralube, but it is no longer being made.  I now use a good quality oil on rotating parts and a grease designed for high pressure applications on the sliding parts like the mainspring hook and the frizzen foot.
There are many good lubes available these days.  The most important point is to USE them.  That is a concept some guys just don't understand.  How in the heck do they keep a car running!

I trust not greases or wax-base oils for they fail in cold or wet weather. Once per year I disassemble locks completely, clean thoroughly with toluene and brush. Apply two coats Jet Lube Moly Mist to all surfaces and let dry completely before reassemble. Then thin film Kw's synthetic gun oil on contact points. Shot four guns no problems throughout day with warmest being -31°C.

     When my kids were in Scouts we used Moly Disulfide on the axels and bearing surfaces of their pine block racers.  We won a few trophies, until they made it illegal to use...A little messy, but sure reduces friction.

 Although modern lubes are better, I knew and old time Alaska bear hunting guide who used to insist that his clients disassemble their rifles and degrease the bolts ect with gasoline and put NO lube on them during the hunt. he had had some close calls with bears due to malfunctionind well oiled rifles.

So would something like Ballistol oil be sufficient for the internals inside the lock? I must admit I never heard of using grease inside the lock,  I just always used oil.

That being about -24 Fahrenheit. The only thing I'll be shooting, is "the bull".

With the mention of temperatures, I would point out that when hunting in minus 25 and less , I'm more concerned about the springs in the lock than whether or not my bear oil will gum things up [ it won't ]  I missed a shot on a nice deer some 20 years ago . Bringing the lock to full cock, the main spring snapped.  I had fired that rifle at least 1000 times before without a problem, but not in that kind of cold..  Now, I anneal all the springs in my locks myself, just to be sure, and I always carry spares.
