Lube Questions

[unclenick]

Veral,

My questions are about mold lubrication.  Over the years lubrication technology has changed.  One outfit advertises a pH neutral form of sub-micron molybdenum disulphide (moly) in a solvent suspension.  He claims it is a semi-permenant lube for rifle bores.  Anyway, I wondered if this kind of lube might make a permenant substitute for smoking mold cavities, or perhaps even be useful for the sprueplate sliding surfaces?  It should take the heat.

Also, I want to buy some of your bullet lube.  If I buy just one formulation to serve both for mold lube and for bullets, which would be best?  I have the RCBS lubri-sizer and a heater for it that I bought on-sale, so I can use any of your three versions.

Thanks,
Nick

I cannot knock the moly lube you describe, because I have no experiance with it, but it sounds like it would work well.  Molds will not be hurt with trying anything, so long as one watches closely for galling and binding, and reapply lubricant when needed.  -- LBT mold lube is just powdered graphite and beeswax, and must be reapplied as needed to keep the sprue plate sliding smoothly.  It works well with other high temperature bearing areas as well, such as wood stove hinges etc, but the dry moly lubes which I have tried don't.  With LBT mold lube, the beeswax is a carrier or spreader for the graphite and keeps it spread across the area needing lubrication.  Anything I've tried which is bone dry will scuff off in the high friction areas and fail at that point quite quickly.  So our mold lube is not for bullets, just molds etc. as explained above.

   All of our LBT lubricants are equal in performance, so select the one you want depending on whether you have a lubricator heater etc as described in the catalog.
