What is this Lube?

I have been made aware of a company in Louisiana that sells cast bullets that are not lubed in a traditional manner. As sold they are green in color. As I understand the process, after the bullets are cast they are dipped in a "proprietary compound"
that is then baked on. After the bullets are cooled they are sized and ready for use. Here's a link to their website. http://www.bayoubullets.net/
There is a demonstration video and there is very little smoke and they claim no leading.
What is this lube? Anybody know? Sounds interesting. I wonder if it is available?

I wonder if Robars Np3 coating wouldnt do the same thing if you could get ahold of it.

it's not a lube it's a coating.
it's used in australia and other countries and is just starting to take hold here.

It appears we have two threads that I am in that are kinda spiraling around each other.

Yeah, Bayou Bullets. That is owned by Jerry Miculek's brother, Donnie.

I talked to Donnie over the phone a few months ago because I was running into hiccups trying to coat my home cast boolits with this Sandstrom 27A liquid. It is some sort of moly coating.

He gave me some hints/tips.

And at the time he wasn't aware of the Sandstrom 27A liquid.

The Sandstrom folks way back when I ordered a quart confirmed that some of the other moly coating bullet manufacturers (possibly Precision, Black Bullets Int'l, and/or Bear Creek bullets) were using their 27 A liquid.

I am inclined to think that the less smoke you see in that video is a result of using some powder like Winchester Super Target or Solo1000, not necessarily because of the proprietary coating.

This past summer I did an experiment where I shot UNlubed cast boolits out of 1911's. They still smoked. :veryconfu And that was with either Clays or Titegroup powder... probably Clays.

Yeah, RN, it also contain antimony trioxide. That one is the dangerous one, and combined with the MEK to keep it wet it makes it especially questionable for "home" use. Be careful and treat it as fumes coming off of the pot. ... felix

The coating that Donnie is using is stated by him not to have any moly in it.
This according to a thread on a local forum here. Below are two direct quotes from that thread.



(Just exactly what this stuff is, he won't say. I asked, and was told 'Its a proprietary coating'. Which is innovator talk for "None of your business".)



(Moly-coated bullets have been around for years. But the graphite-based molybdenum compounds are, if anything, even messier than conventional lubricant. Donnie emphatically stated that there is NO moly of any sort in his coating. I can believe it.)

The Coating as used by Bayou, is both a coating and lubricant as one product.
When the alloy is coated, and coating baked, then sized, the resulting film self lubricates and separates metals, and requires no other lube.
It is not affected at heat at 190-200C aside from getting harder and more slippery.
It differentiates from all other coatings and lubes that the cotaing has ability to self react to firing conditions and cope with hydraulic deformations without leaving any deposits.
The coating does not contain any heavy metals, that are contained in many other lube systems.

Generally all lubes and coatings can be considered messy. I suppose that the messiness factor will depend on how a set up is established to aplly these lubes, and, if the final results meet users requirements.

Proprietary means just that. I do not believe that a designer/manufacturer of a unique material will simply hand over the formulation to any one that asks.
I simply find it curious, that the minute any one seems to get something right, every one wants the recipe, and hang any proprietary matter considerations.

The HI-TEK-LUBE coatings do not contain any Moly Disulphide.
Many do not know, that Moly Disulphide will ignite and burn and generate Sulphurous irritating fumes. In right conditions, Moly Disulphide may form Sulphuric Acid fumes, seen as white clouds with moist air. Because of formation of acidic vapours when Moly is burnt, and, if there is also a possibility of generation of atomised Lead, due to incomplete lubrication, then there may also be a possibility of formation of solubilised Lead salts in gasseous emissions.
Such acidic fumes generated by burning moly disulphide, are also corrosive to steel materials, and can be considered damaging to the bores of guns.
This can be considered counter productive for the desired application.

Moly is an excellent lube but care is needed as to where and how it is used.

The Moly to sulfuric acid story is a myth. See above link.

If you think it is myth, then just simply get some moly, and ignite it with a match.
Smell the fumes if you dare, and then advise what you experience. The Moly is more reactive with fire the smaller the particles.
With adequate air (Oxygen) and right conditions, (Fire Heat and Oxidisers) the burning of Moly produces Sulfur Dioxide and Moly Oxide which is also black powder residue.
This black residues in guns are difficult to distinguish from actual Moly Disulphide.
Please read Material safety data sheet (attached),where it clearly states that material with Thermal decomposition may release toxic and/or hazardous gases.
What do you think gun powder heat and the temperature produced with powder burning will do to the Moly Disulphide????
If adequate Moly Disulphide powder is generated as dust, and is ignited with powder burning, then you can get Sulphur Dioxide gasses being produces and well as Molybdenum Oxide dust.
I would hate to be shooting next to you when that happens.
I would appreciate your reply after your investigation.

SO2 does not form Sulfuric acid. Sulfuric acid can be formed by flowing SO2 gas over a hot platinum or vanadium pentoxide catalyst and dissolving the resultant SO3 gas in water. These conditions are not met in a firearm.

If burning sulfur created anything that corrosive then the black powder shooters would all be replacing their barrels quite often since BP is 10% sulfur.

If you'd like to sell your product do it by representing it's positive aspects not by misinformation about other products.

Thanks for the heads up.
I will try to comply.
You seem to have ingnored the warnings on the MSDS on Moly disulphide, about generating fumes with burning.
I am referring to formation of Sulphur Oxides, that in moist conditions will corrode even Stainless steel.. Sulphur Dioxide is an acidic gas that is readily soluble in water and moist air.
Many folk are affected with SO2 with allergic reactions.
I could also consider using Moly in the coatings, but do not wish to do so.
I have seen a manufacturing company making gease type lubricants have a fire from ignited Moly disulphide that settled on rafters on building framework. The factory was evacuated as people could not breathe from choking fumes.
I just will ignore such event and will refrain from making any alleged misleading statements.

SO2 does form Sulphurous acid however (H2SO3) on contact with water/water vapor. Not as bad as sulphuric, but still bad. I used to manage a plant that made sulphuric acid.
