Moly

[Ruskin]

I have some moly bullets.  I am wondering if the moly does anything for accuracy or barrel fouling.  Is it better to forgo loading a moly bullet?

What about the barrel?  Does it coat the barrel?  If so does it change the point of impact?  Is it hard to get out?

Your thoughts?

Wouldn't shoot moly in anything I own. Here's why:
Any moly is corrosive if it does not contain an inhibitor to neutralize the naturally occurring acidic quality of the moly. Dry moly is particularly bad as it is chemically impossible to add an inhibitor to dry moly. Even the most highly refined and pure moly will contain (among other compounds/elements) some Sulfur and Sulfur Dioxide (S02). When the Sulfur or Sulfur Dioxide is exposed to the humidity in air, it combines with water vapor to form Sulfuric Acid (H2S04) which then immediately attacks any metal. The higher the humidity the more acid is formed and the more corrosion which takes place. One cannot detect this corrosion by simple examination as it takes place between the moly crystal and the substrate and is hidden by the moly crystal covering it. Corrosion can only be seen by first removing all moly thereby exposing the corrosion to view. Those who fire bullets coated with dry moly will have little corrosion as long as firing is being done as the heat from firing drives off the moisture. However, as soon as a firing session stops and there upon cools down, water vapor will begin to be absorbed by the moly and corrosion begins. And, the longer between firing sessions, the more corrosion which will take place. The corrosive properties of uninhibited or dry moly have been well documented by military testing as far back as 1968.

I also would shoot moly in nothing I own.

First of all, the reason for moly is to decrease fouling so you don't have to clean as often.  I don't need to shoot 100 or 200 bullets without cleaning so it's of no advantage to me.

Secondly, it is VERY hard to get out.  Kenny Jarret of Jarret rife fame gave a talk at the 2008 SCI convention.  He described getting moly out of a barrel.  It came out after he heated the barrel cherry red with a torch.  Since he makes his own barrels, I guess he can afford to torch one once in awhile; I can't.

Tried it once in a .243 Encore pistol. Sweet shooting little gun before I shot the moly thru it. The moly bullets shot poorly, and it took a $17 bottle of special solvent to clean the barrel so that the gun would shoot good again.
Will never touch the stuff again.

I read somewhere you could clean the Molly off with some type of "electronic contact cleaner" I  cleaned a few with steel wool. I'll do that if I have to.   TVC15

  I used a can of electronic parts cleaner to remove moly from some bullets . I also dumped some in a tumbler and ran them overnight to do the same thing. I found moly to be OK for shooting. NOT any more accurate than bare bullets. It DID take several shots for the barrel/load to settle in. The Moly loads needed a few grains MORE powder to reach the same velocity as the bare ones. Something to do with pressure being less so the bullets exited quicker at less velocity! You have to make sure you don't get a "layering" of Moly and jacket fouling. This is VERY hard to remove as you only get one layer at a time.
  To prevent this "layering" you must treat the bore BEFORE shooting coated bullets. Then you get Moly riding on Moly. It isn't hard to coat bullets your self, it just takes a few hours. Or spend a few dollars for some one else to do it. Personally I would not waste my time or $$ on them again.
