Danzac coating?
- Thread starter Splatter
- Start date
Been doing it for about 8 years. Presently I am not coating match bullets because the tumbler system I was using was damaging the meplats of the bullets causing me to take more material from the bullet when I trimmed meplats. I never tried a vibratory tumbler.
Splatter, what did you want to know?

Ok I read a great long thread, and I've come out with this:
Barrel temperature is reduced, a big plus for people with thinner barrels or semi-autos. (velocity drops a bit too, but even with extra powder to get velocity back up the reduced friction should still keep temperatures lower than an uncoated bore)
Moly or TD makes bullets 'sleeker' because they don't get big 'fins' pressed into them by the rifling. That comes from da Germans, so it's got to vee precise. Sleeker=higher B/C
Moly-coated bullets do not coat a bore evenly. This means you have to shoot a bunch to get a bore coated. (this is wasted shots, and thus wasted money). And if it gets coated some parts could have more than others. Using bullets to spread moly around is just dumb and wasteful and not consistent. And there's concern that you could just be trapping fouling in layers, fouling and covering it with moly, and fouling and covering, and fouling...
The biggest concern is possible inconsistency.
You have to clean in a special way, "Berger's recommended cleaning method using JB and Kroil"
And over the course of a millenia the steel may be weakened by the moly compound.
So I guess the best thing is to use that Danzac stuff, and put it on a patch and run it down your bore after you've cleaned it, and just shoot plain bullets. This way you have consistency, the barrel is always coated evenly and predictably, and if it wears off or the barrel gets too dirty or something, and shots become erratic, then just clean and re-apply.
-more info:
Seems that with tungsten disulphide there will be little or no copper fouling, so there will be much less frequent need for any cleaning. And you don't want to remove it once it's on the barrel anyway.
(The lack of copper fouling makes sense, since the bullets aren't getting deformed and having 'fins' pressed into them.)
And some people have barrels with 7500 shots through them and are still looking good, using TD.
And I found a supplier, since that DANZAC thing is dead as a Dodo, and Sinclairs doesn't sell any TD coatings. Plus they're in Canada, so cheap shipping

Anyone want to split a 170kg drum? $30/kg, you can't beat that...

Oh yes, and you can buy just the powder and mix it with alcohol, which will evaporate away, for a great coating method!
Slightly OT:
I read that if you put a bit of moly on the trigger catch it will break much cleaner.

Heh I was kidding, they also sell sample sizes. Grease from $13 and powder by the pound for $48. From my understanding that's a dozen life-time supplies.
I'd order some right now, but I want to talk to them on the phone. I'm pretty pretty sure that alcohol and powder mixed, put on a patch, and run through the barrel would be the best way to apply it... But they're the experts, they might say one of their grease types is better.
Hell, I'll probably throw some in the oil on my Jeep, it can't hurt.
But damn, 7500 rounds some guy got through his barrel and it's still going strong.

Danzac
I have recently been using Danzac (Tungsten Disulfide). It was recommended to me by both "Humble Henry" Rivers and "Smokin Joe" Entrekin. It is easier to clean, and I don't have much copper fouling problems. Danzac is a high temperature lubricant. As to barrel life, Joe Entrekin's "Grey Mare" is over 7500 rounds, and still shooting well. We used a bore scope on it yesterday, and it appears fine. It still shoots fine. I think Joe is going to try to get over 10,000 rounds thru it. Be advised that a little bit goes a very long way. I coated 1000 rounds with a Pepsi cap's worth, and have enough to coat another 1000 from that initial cap's worth of Danzac. This included coating the BB's in the tumbler. It works great.

Got the high-temp grease and powder both coming. Good guys to deal with.
And O.T. I was curious so I asked, and if you throw some in your oil it does help the car. They recommend 15g per litre for the first 5 changes, and then your engine should be completely coated.

$45 including taxes per lb.
If he quoted $90 maybe they're not such nice guys after all!
But if we go for bulk it's about $15/lb. ...
Incidentally I remember reading that if you get tungsten under your skin it can cause tumors. Not sure if that still applies with WS2, but I'm not going to take any chances. I'll be handling the stuff with a mask, gloves and glasses - even though their data sheet says it's safe. Heavy metals are heavy metals.
