Tungsten Disulphide (WS2)

[jo191145]

I'll throw a few tips in.
I use my Hornady case gauge for prepping the bore to keep my chambers from getting any lube in them. Unless you have a high end cartridge specific bore guide I think it's a good idea. I have used Kroil but stopped that practice because of it's creeping ability.
Toss a few patches in the tumbler when coating bullets and you'll have a nice supply of pretreated patches for that lot of bullets. Saves a little on the mess factor.

Greyfox if the BB's didn't work for you how are you applying WS2 to your bullets. I went back and read all post but found nothing to how you are doing it. Even another guy said that he did just like you but didn't say.

You misunderstood what I was saying (I probably didn't make it clear). The BBs didn't do anything wrong they just added an unnecessary step to coating. I was bullets in acetone, dry and put in a square sided pasta sauce jar (forget what size, but it's smaller than a quart). I will coat as many as 500 68gr 6mm bullets at a time. I add a small amount of WS2, put the lid on tight and tumble in a Thumler for as short as an hour or as long as all night if I forget about it. Then I empty the coated bullets on a towel or into a tube sock and remove the excess dust/WS2. That's it.

Rick is a good friend of mine, and there is more than one way to skin this cat, but my preferred method is the Lyman moly coating kit, minus the moly, of course. We just use different methods that both work. The Lyman kit is pretty inexpensive and gives good results, for me. I simply use it like it's designed for using except replace the moly with danzac(td). Everything else is very similar to what Rick describes. You can skip the cleaning, but bullets coat better and faster if cleaned like he described. Another thing is that warming the bullets helps, but I think that's due to lower humidity in the bowl, TD gets clammy and doesn't coat as pretty and evenly as if it were very dry...just from humidity in the air. In the summertime, it's as simple as laying the acetone(or similar) washed bullets out to dry in the sun before adding them to the tumbler. In the winter, I use a heat lamp over the tumbler, before and during the coating process. It just dries everything up nicely and yields a better job, IMHO.


The two biggest differences between what Rick and I do are the type of tumbler and the media. He uses a Thumlers Tumbler...I use a RCBS vibratory cleaner with the smaller Lyman bowl that is made to fit inside of the RCBS bowl.


The other difference is the tumbling media. Rick's method lets the bullets themselves impact against one another to do the plating. In my method, the Lyman kit includes ceramic media that does the impacting.


Again, two different methods that both work...I just like mine better or I'd do it like he does.---Mike Ezell

There are great discussions out there about using plain water with dry lube(of choice) for bullet coating. I think I may try this next batch of bullets.

That is, same as described, but adding water to the container to cause slurry. I would not have thought it would work, but the results I've seen pictured really look good.

That is surprising. I dump my bullets in acetone to remove any bullet lube, and if I don't let them dry in the sun for several hours, and I proceed to tumble them ( rotary, with shot and a tiny bit of WS2) I end up with translucently coated bullets and a gummy mess. Apparently the hollow point cavity in my bullets retains the acetone for a long time. I really try to avoid using water on my cases and bullets used in competition.
