I read a few things on the interenet and saw a commercial cast bullet that uses moly. It seems like the holy grail of casting. Supposedly it eliminated leading almost completely and since there is no other lube used eliminates smoke.
Whats the catch and where can I get some?

If he is talking about the moly coated bullets like Precision (http://www.precisionbullets.com/), he won't get what he is looking for with a moly lube. Good bullets, by the way.

I have read that Sandstorm is the company that makes the coating materiel for moly/poly coated bullets.
I have used Billy Bullets and they work well. A hard coating that provides a lube.

Now i have to ask the wife to bake for me :D Q: What is the coating?
A: We use a proprietary solid dry film lubricant. This is similar to the moly/poly coatings on the market but is much tougher. We bake the coating onto the bullets, then restrike the bullets in carbide dies after the coating is applied.

The "Moly" manufacturers and folks at home use to "Moly coat" jacketed bullets is very different than the "Moly" coated lead bullets. Moly is a fraction of the coating, but it sounds good and helps make em slick.

There's been sprays that coat pretty well with moly. Back in the 70's there was a company that made a liquid that came in cans, that was basically a moly PAINT. It was made for cast boolits, but it only worked on very hard cast boolits, even then it didn't work well alone, it needed a regular wax based lube as well. Besides the solvents in it were wicked, it had to be used with a lot of ventilation.

The only way a home based reloader could do it would be to get a moly coating kit from Midway, or another loading supplier. They consist of a tub of technical grade moly, along with instructions on how to use your vibratory tumbler to coat bullet/boolits.

I use a pill bottle with Ľ cup of steel BB's and a teaspoon of moly powder. Put this in a tumbler with media in it, let it tumble for 3 hours. Here's the kit I got;---well I see midway no longer offers it, but here's a link to the Lyman moly kit, and seperate components of that kit.

If you already have a tumbler, then the moly is available alone here;

With the moly alone, a pill bottle, some steel BB's, and whatever media you're using, you can coat your boolits. Be aware, the molly makes a mess. It'll get all over you and anything it touches. It does wash off, but yer better half is going to anoid!

I also see Lyman has a spray moly;

Dunno nuthin about this stuff, just mentioning it.

If you're referring to the black bullets--like the now defunct Master Blaster--you have to play with powders. They do smoke, but certain powders are more kind than others. I can testify that with Bullseye they put out a fair bit.

OH! If you'd have said that to begin with, I'd have saved the time it took to fish out those links to powdered moly coating systems.

Simple answer is YOU CAN'T DO THAT AT HOME. Pony up, pay the price of those precision bullets!

Frequently Asked Questions http://www.precisionbullets.com/

Q: Do I use reloading data for lead or jacketed bullets?
A: You will use lead reloading data for Precision Bullets.
Q: Can I use Precision Bullets in my Glock?
A: Yes and No. We have many Glock shooters using Precision Bullets in factory Glock barrels with great results. However, I tell all Glock shooters it is try and see. If you have tried plated bullets and accuracy was good without keyholing, then ours should be fine. If you have tried traditional cast lead bullets and accuracy was good after 200+ rounds without heavy fouling, then our bullets will work fine and shoot a lot cleaner.
If your Glock won’t shoot Precision Bullets, then it will have problems fast—heavy fouling in 50 to 100 rounds, very poor accuracy, keyholing, etc. Then you will have to stick with jacketed bullets. However, this is very rare.
Q: Can I pick out my bullets at the factory?
A: No—we are not set up for retail sales at our factory. Due to insurance and the proprietary nature of our coding and equipment, we run a closed facility. All prices on the web site include shipping.
Q: What is the coating?
A: We use a proprietary solid dry film lubricant. This is similar to the moly/poly coatings on the market but is much tougher. We bake the coating onto the bullets, then restrike the bullets in carbide dies after the coating is applied.
Q: Will Precision Bullets work in my HK?
A: No—we have had customers try our bullets in HK’s with the polygonal rifling , but the results were poor.
Q: Can I use Precision Bullets in my 38 Super Open gun?
A: No—we don’t recommend our bullets for compensated guns. When the bullet passes through the compensator, the gases are diverted and will cut the base of the bullet causing way too much smoke and leading. Stick with JHP’s.
Q: Does Precision Bullets have a dealer discount program?
A: Not at this time. We use the volume discounts listed at the bottom of our product page.
Q: How do I become a sponsored shooter for Precision Bullets?
A: At this time, we are not adding sponsored shooters.

RELOADING INFO


Handloads.com Maass IPSC Loads Steve's Reloading Pages The Reload Bench

Any powders for cast lead bullets will work for Precision Bullets.
Recommended Powders
Vihtavuori – N-320/N-340
Ramshot – Competition/Zip
Winchester – WST
Alliant – American Select/Power Pistol
Hodgdon – Universal Clays/HP38

Not Recommended Powders
Hodgdon – Titegroup
Vihtavuori – N-310

Note: If you are having a fouling problem or too much smoke, try a little slower powder. (powder burn rate chart)

Top of Page



RELOADING TIPS
Make sure to have a good bell on the case so not to shave off the coating during the seating process.
Do not seat and crimp the bullets in the same die. Use a separate taper crimp die.
We highly recommend Dillon reloading equipment.
Do not use a roll crimp or Lee Factory Taper Crimp Dies.
The roll crimp will cut through the coating. You must use a taper crimp die.
The Lee Factory Taper Crimp Die will undersize the bullets causing accuracy and fouling problems.
Most of the time a heavier crimp will work better.

TROUBLESHOOTING
Too much smoke and fouling
Make sure you have a good bell on the case and not shaving through the coating during the seating process.
If you are using brand new brass, make sure there is not a sharp edge on the inside of the case mouth (try used brass).
Make sure you have a good crimp.
If you are using the Lee Factory Taper Crimp Die, try switching to a standard taper crimp die.
If you are seating and crimping in the same die, try switching to a separate seater and taper die.
Try a slower powder.
Slug your bore, oversized bores will foul heavily and be inaccurate. (Midway USA sells a good slugging kit.)

CLEANING YOUR BORE
Normal cleaning methods will work for our bullets, but sometimes the coating will stay in the barrel. If you cannot remove the coating with traditional cleaners—Shooter’s Choice, Breakfree, etc.—see methods below.
Stainless steel barrels only
50/50 mixture of hydrogen peroxide and vinegar in a jar
Make a hook out of a paper clip
Remove barrel and lower into mixture with paper clip hook
Soak for 20 minutes
Remove barrel and wipe off excess with paper towel
1 pass with a bore brush
1 pass with a tight patch
Flush out under sink with water
Dry off, patch out, and oil
Carbon steel barrels
Take a “Chore Boy” stainless steel scrubbing pad
Cut off a spiral portion from the pad
Wrap around brass cleaning brush
Apply Breakfree CLP—5 or 6 passes through the bore
Patch out with favorite cleaner
Dry the bore and oil
