No one, I mean no one moly coats like me...

All I know is what I have read regarding steps to apply both moly and ws2 and my success with ws2. There are less steps for ws2 which is why I chose it as my preferred coating. Never claimed one to be better than the other. I don't know why you have been so defensive and rude but it's Uncalled for. Have a nice day hassle someone else.

All I am trying to say is hear say may not be correct, and if you have no real experience Why do you feel u need to have to comment on something you read? The world was flat at one time. My last comment on this.
 
Small amounts of moisture combine with the sulfur in moly disulphide to create concentrated sulphuric acid. Want corrosion? H2SO4 is a good way to get it.

Oh bull... Just bull.

Even if that chemistry is possible under incredibly particular conditions it does not happen with bullet coatings. This whole notion that moly causes rust is just bull. Considering the 10,000 moly coatings used in machine lubrication. It's just bull!!
 
I think David Tubb won about 20 national championships shooting moly bullets. Walt Berger set a world record shooting moly, and John Whidden dominates today shooting moly. And no one complains about rust.

I think someone had a bug in their butt about the Neco process where they used WAX TO COAT THE BULLETS.

If I were going to see a culprit there in rusting my barrels I might look at the wax, but that's just me.

I don't have a dog in this fight but I do read the chemistry literature.

From https://doi.org/10.1016/S0167-8922(99)80018-2

"Laboratory tests confirm that in the absence of effective corrosion inhibitors molybdenum disulphide can cause corrosion in humid environments. Apart from the corrosivity of the molybdenum disulphide itself, molybdenum disulphide films give relatively little physical protection to metal surfaces. Burnished films are fairly permeable, and the crystal structure is itself permeable to vapors and gases. The oxidation mechanism, which is thermodynamically favored, is the one which leads to the production of sulphuric acid. Even in the virtual absence of moisture, molybdenum disulphide can react with iron or other metals to produce the corresponding sulphide. The formation of iron sulphide, or any other metal sulphide, and subsequent hydrolysis to release hydrogen sulphide, represents a corrosion process."

Yup that's it. Comes up every time.

Like I said I have moly coated bullets that are ten years old that still look as shiny as the day I made them. Why aren't they oxidized?
 
Not true bubba. Who cares about the bullets?
You can find corrosion where ever sulphur and moisture get together including in your rifle barrels.

Urban, as you can see moly is a very sensitive subject for some... It’s basically like beating a dead horse. None the less I think we are in the same boat. All these theory’s about the awfulness of moly yet in the real world not one of the top shooters have seen these horrible, horrible effects... speaking of which - time for me to go Moly a couple thousand Hybrids.
 
Does that mean you like brawndo?
I take it you are not technically inclined.
I was involved in a project to replace the insulator pucks on the Blackhawk helicopters equipped with the Quickfix system.
In that case the sulphur came from the engine exhaust and the moisture came from morning dew. And you got to pay for it with your tax money. It is real....

Brawndo. It's what plants crave.

Back when folks used moly way back i tried it. Only time ive ever had corrosion in a stainless barrel. Weird stuff. Folks use it to not have to clean but carbon still happens.

Everyone to his own methods. Back in early 1997, I tried the moly-coated bullets in my 6 PPC. At first they seemed to work well, but there was a build-up that took a lot of scrubbing with JB to get rid of it. When I talked to Speedy Gonzalez and the late Don Gentner, I discovered that these two bullet makers were totally against coating bullets. Don was almost offended that anyone would take his carefully made bullets and beat them with steel balls and coat with a substance that did not improve accuracy. Also, he stated that the shooter had to increase powder charge to get back to his desired velocity.
Speedy took another approach and encouraged all of his competitors to use moly....because he would worry less about them beating him. Of course, he said this with a somewhat "tongue-in-cheek" attitude, but he may have been serious.
I quit the moly habit back in '97 and haven't regretted it. Good shooting....James
 
I predict there will now be dozens of posts condemning moly coated bullets. Once it starts its like an infection.

There will be a series of name dropping posts of course, with so and so said this and so and so said that, and he's an expert of course... And the obligatory "I tried it once and ruined my best barrel" stories, you gotta have a few of those or the pile on would not be complete. I mean, it's tiresome in its repetition.

I would love just one time to share what I do on the subject, and people to look at it and say "maybe I was doing it wrong".

You win best post. :)
 
Whether you use Moly, or hBN, the coating on the bullet reduces friction, and friction generates heat. It also allows you to extend strings between cleanings. For those witnessing bullet jackets coming apart on certain bullets, coat a few of those bullets with either of the above products, shoot them in the same gun, and you will likely see the bullets remain intact.

Edit: If you are going to plate your bullets, use a plating method. Stainless Steel balls, or my preferred method… ceramic media. Wet coating is just that… a superficial coating. Like a car wash that sprays liquid wax on your vehicle:rolleyes:

Well for those that actually apply it correctly, know how to handle it, know how to clean their barrels, there are absolutely no disadvantages. There is NO accuracy loss, you can shoot longer strings between cleanings before accuracy tanks off, better barrel life, and easier cleaning. OK I guess one disadvantage is that you will likely never talk anyone into doing it because it was not advertised like the Creedmoor and due to all these false statements made about Moly. Some of the best LR BR shooters through out the past number of years have used it and 1000 yd records have been held with Moly bullets. Believe it or not but Moly works, no matter how many people say it doesn’t.
 
So i have tried to remove wet method moly coated bullets. It was a 6 hrs process in the tumbler with fresh media to remove about 70%ish of the moly never was able toto remove 100 %. Do your a favor try doing it wet method and then try removing it. You will see its not superficial.
