[QUOTE="Calvin45, post: 1815598, member: 109862"] Hexagonal Boron Nitride happened. It is superior in every possible way. Molybdenum disulphide burns at something like 800 Fahrenheit. It gets way hotter than that in the tube. Hbn is a ceramic technically, and does not burn or undergo chemical change of any kind until temperatures exceeding the melting point of the steel in your barrel, it actually protects the barrel and greatly slows down throat erosion because of this. Moly is dirty to work with, makes a big old mess! HBN does not (though make sure not to breathe the dust in, as with any fine powder). Moly (and tungsten disulphide, another lubricant coating) is a sulfide which means it has an affinity for water and can even combine with it to make a mildly acidic result. Moisture and acid are no friend to your firearm! HBN has no such affinity for water binding, does not combine with water, and is not even remotely corrosive under any circumstance. moly sits on the surface of projectiles and barrels. Hbn, if proper particle size is used, actually impregnates the microscopic pores of the metal, bullets and barrel. Once applied you don’t have to worry about sloughing it off. You don’t have to see it for it to be there and do it’s job. [/QUOTE]
