Colloidal graphite as an action lube.

[DarkStar]

Several threads exist about using colloidal graphite as a barrel treatment. Would there be any positives or negatives using it as a bolt lug lubricant in conjunction with grease on the lugs? My hazy early morning thoughts make me think it could be a super fine final insurance layer against galling.

No need to put anything other than a quality EP grease. You may alter the qualities of the grease for the worse.

Big negative, it is not intended for an application where pressure is exerted on the intended surface.

I’m a big fan of colloidal graphite but not for locking lugs.

Graphite’s a fine lubricant for certain uses but I don’t count the high pressure bolt lug interfaces in modern rifles among them.

Would that also include bores, since a bullet passing will be pressure exerted ?

Since Moly has been around a long time, obviously, no, talking about 2 sliding surfaces under pressure.

Two different conditions entirely: one exhibits sliding, transient friction while accompanied by high heat, the other has higher peak peak pressures with no movement until the pressure's relieved.

Some shooters use it on a patch,after cleaning for Cold Bore 1st shot,liqiud evaporites,leaving the graphite in barrel.Like LOCK EASE has to be superfine graphite
