wiljenTungsten Disulfide as a dry lube
Has anyone ever used, attempted, thought about, using Tungsten disulfide as a dry bullet lube. It looks to me like its .5 micron size and lubricity would make it compare favorably to moly. Am I missing something that makes it unsuitable ?

popenmannThe jacketed benchrest boys are playing around with several coatings, that may be one of them, I don't remember.
With regard to lead bullets, you completely miss the point of bullet lubricant. The #1 function of a cast bullet lube is to improve the gas seal. Lubrication is a distant second place.

wiljenWas honestly thinking in addition too rather than as a replacement for the wax based lubes. I know it would not do anything to help the seal but am seeing several commercial casting outfits that use both a wax based lube and then a dry(powder) lube over the finished product

jeffeossotungsten -- VERY HARD....
lubricity may be fine in atmosphere, but remember, graphite in vaccum or under great pressure, is abrasive.

good point jeffe. most of us are not metalurgists, engineers or ballisticians and would not know that.
thats why we pay you those exorbitant wages. just kiddin' ya.
thanks.

<xs headspace>Yeah, tungsten is hard, but this is tungsten DISULPHIDE. Read the specs on it--it's a lube that holds up under extreme pressure. The molecules act like nano/micro ball bearings, filling in the tiny roughness in the two sliding surfaces.

<xs headspace>Oh, yeah---never tried it for cast bullets, but moly on paper patched bullets is just like sex-messy, but nice.
