I've seen lead bullets listed as Moly coated. Is this a superior lube to what is normally available? What problem does the molybydenum address? Do I get less leading, faster velocities? I have six ounces of the stuff sitting in a box and lead bullets already lubed by the manufacturer. Do I just dump the bullets and a small amount of moly into a tumbler?

[swifter]

Keeping in mind that I cast, size, molyplate & molylube my own, and it has reduced leading to almost none, what I think I'd do in your situation is either roll the lubed bullets in the moly powder to imbed it in the lube, or shake the bullets with a little powder in a plastic tub to do much the same thing. One major reason I do my own is because they come prelubed...:(
Generally too hard, too, but a six month wait cures that.
Hope this helps,

With bullets that fit the bore, are of the correct hardness, lubed with a decent lube, and are loaded correctly there is zero leading. I would not moly coat lead bullets. Moly is extremely hard to remove from the bore once it is coated. Moly is hydroscopic as well. Moly serves no purpose in firearms other than marketing products to people....

Moly on bullets traversing your barrel leaves some moly which attracts moisture therefore pitting your barrel.

Also moly coated bullets are fired it becomes another contaminant in the air to breathe and also whle becoming aorborne when handling it, it is reputed to be worse on your lungs than asbestos.

I feel it is something that should not be marketed at all to shooters.

You guys missed the:" It turns to radioactive waste and causes your children to be born with two heads" myth. Other than that, you got all the urban myths...:neener:

I, with all respect due:p , disagree, gentlemen.

Tom, moly being hydroscopic is common knowledge and fact, nothing to discuss there.

Moly "works" by attaching to a surface and having a chain of 9 moly molecules making a "barrier" between friction surfaces, and it is this lubricious barrier that reduces friction. The moly that gets worn or broken from the chain of 9 attaches to the first chain that is less than 9, yet it won't exceed a chain of 9 molecules. Pretty cool. Always a chain of 9 between surfaces when free moly molecules are available. The problem lies in the EXTREME environment of a gun barrel, moly will not withstand it so the chains are broken until another coating is provided. So you run another coated bullet down the pipe and it replaces the moly, great right? Nope, it too gets damaged by the powder gasses and ash and flame and pressure that is following that bullet. It does not reduce barrel wear by any significant margin, or at the least it has never been proven scientifically that it does. So you go to get it out when you figure out that the only thing it provides is cool factor and expense. Good luck breaking the molecular bond and getting all of it out by hand. You can shoot it out, but not easily or quickly.

I have done the research and the testing. I too respectfully disagree.

All I have read about Moly coating does not impress me ... theory seems fine - at first.! A buddy of mine is convinced he ruined a match bull barrel on his .270 thru Moly ... hard to prove/disprove ... but it ain't for me.

Small amount of leading? No real prob ... Lewis lead remover is a short and simple answer.:)

Sounds like some of you guys first reloads used fletching and flint.

I think Molly/polymer hard dry coated bullets are fine performers and pose no safety issues. They don't smoke. They are cheap.

They do not build up moly in your bore that needs any special cleaning beyond a pass with a brush and a patch.

I think some of the info here may be a bit dated.

[Gary H]

So, anyone have studies..tests..etc. to support their position on Moly. I understood that barrel erosion might be a problem if you didn't coat a very clean, dry barrel first and used only moly bullets. Any citations..URLs?

[swifter]

All I can say is, I've read the tests done by Dupont and Norma, I've used moly for about 10 years now and have experienced exactly none of the pitting or other problems I've read about. I molyplate my own bullets, both jacketed and lead, and clean my bores on a regular basis. Based on this, I think moly works really well for me. I plan to continue using it. I'm willing to share my techniques with folks, with the caveat: YMMV!
I've been reloading about 30 years, and handloading close to 20 now. I've learned a few things. I don't know it all, but I'm pretty positive about what works for me.
