what type of bolt lug grease??

Just a question about the question, but who has had a problem with galling and/or headspacing opening up due to wear?

I was once shooting in a dusty place (Raton) and got a snootful of dust in my action. That evening I flushed it out with a brake-cleaner-like spray product (made quite a river of muddy solvent). I neglected to re-grease; both my action and my bolt lugs were (super) "dry". The next morning, on the second or third shot, I felt the lugs seize and gall. This was just with ordinary opening and closing forces (i.e. the ammo wasn't being jammed in). Admittedly this was an extreme case (bone-dry lugs) but this is what we're trying to avoid. So that action has permanent (though minor) damage to it.

Nice idea on cam assembly lube, my only concern would be if it might "wipe off" or at least "wipe thin" before you get a chance to re-apply a drop... I presume this has worked out OK for you.

All the lube in the world isn't going to stop the high spots of rough machining from flattening, or over pressure loads from setting back action lugs. Opening and closing a bolt isn't really a high wear application, assuming you don't have an action full of dirt. Am I missing something?

Had lugs gall up on a custom bolt. Also had the cocking cam on the same bolt gall. The bolt is fluted, the flutes are all galled up from when they machined them. What ever type of metal it is it galls up bad and I hate it.


I now use Copper Cote an anti seize lube with copper in it. I think the copper in it makes a big difference on rough or gall prone steels like stainless.
Now that I tried it I will probably never use anything else.
 
This all very interesting to me as a novice shooter. But where do I apply this lube on my bolt/action?

I apply a thin coat on the rear of the locking lugs, where they mate with the receiver. I prefer a grease that is quite thin, and that clings well to surfaces.
 
I use a graphite based product called gunslick that I bought years ago!

I also use it on the sear face and primary extraction ramp (where the bolt handle hits the action!)
 
i have sprayed my action and bolt with silicone lube from crappy tire, i was woundering would paste brass sizing lube work as well,???

Silicone is not the best lubricant where there is metal to metal contact. I also avoid spaying any cleaners or lubes directly onto the action, as it seeps into the bedding area, where it can cause problems.
 
Aside from specific products (I like MolySlip AS40 (or AS60) Assembly compound), the key things to look for are:

1.) Moly content is always preferable... the higher the better.

2.) The lubricant used to contain the moly should be rated for High Temp and High Pressure

3.) Just a dab 'll do ya.

4.) Avoid sprays of any kind in the action area -- your beautiful Jewel trigger will thank you.

As stubblejumper said, Silicone is not ideal, as it has a very low surface tension -- which makes it spread too thin in high-pressure situations.
 
So reading this tread I went to the shop to see what various greases I have that I could possibly use...

I came up with "Lucas heavy duty wheel bearing grease" high temp (575*) high pressure and some other thing like "great for marine applications" "won't thin out" etc



Would this be an appropriate substitute for greasing my lugs ??

Based on the MSDS info, this stuff uses a Polyurea thickener in the grease, and while there's nothing wrong with that, polyurea greases have horrible compatibility with all sorts of common grease... Something to keep in mind if you'll be applying a different type of lubricant to the same area.

The nice thing about Moly grease, in general, is that it continues to lubricate even when dry - this can't be said about most other lubricants.
