Obatex Black Powder From South Africa Is The Fastest



A South African company is making a black powder that's faster than Swiss.
The FFF is so light and fluffy that an equal volume only weighs about 1/2 as much as other powders,
and an equal weight and/or volume is generally faster than all other powders by about 200 FPS or more.
The manufacturer recommends only loading 1/2 as much by weight until a person can work up their load by volume.

"In comparison to weight and volume it was clear that Obatex is as a general rule a lot faster than Wano and Swiss.
No more than 55% of your loads for Swiss or 50% for Wano should be shot with this Obatex.
If the same equivalent by weight is used, the velocity is much too high and the extremely fast ignition will burn
through the nipple very quickly, leading to other possible damage on your firearms."

500 grains? That can would be about the size of a small aspirin bottle.

I’d guess that’s 500 grams. 453.59 grams = 1 pound

So what did they do to make it lighter?

I'd like to know the ingredients. Probably not using the traditional stuff. Maybe it's trailboss with black dye??

The leading theory is that they use a very light wood approaching balsa for the charcoal.
The only thing I can see wrong with that is that traditional gunpowder is 15% charcoal and if you replace it with helium that is not going to reduce the powder density by half.

That is the key point. I use to make my own powder and changing the charcoal from one wood to another is possible, but I must to change the proportions accordingly. Charcoal is what is converted into gases, so incredibly as it could seem...changing from a hard or even a mild wood as willow to a lighter or softer one, you will reduce overall weight of the final mixture.

You also get lighter powder if you don't corn it with pressure mills.

That is also right. But I suppose that being a manufacturing facility they do it.

This is the first that I've ever heard of the obatex, b.p. propellent. Very interesting and the story behind it is quite interesting, too. I've never gotten on the website (below) before, but it gives some insight into "world" m.l.s and the restrictions we don't have to deal with here in the U.S., today anyway. The comments on obatex powder is right below the beautiful English patterned flinter with the containers of standard GOEX and Olde Eynsford. the $180.00 per pound comment was a brow-raiser, too. The article is over a year old, too, so I guess this powder has had some time to be usage proven, especially in a country under some serious, harsh restrictions regarding their import of sporting powders. Looks like the powder may be restricted to South Africa's usage only(?) I didn't see any exporting comments on the powder; may have missed it.

If it says "BP" then it is so !!!

True BP is classified as a Class-A explosive where it's replacements are classified as a Combustible mixtures. True BP, has qualities that replacements are "trying" to equal and lots of luck with that. ….

When I first got started in this great adventure, I read where "Willow" made the best Charcoal, we along with the other ingredients went out and bought it. We could not corn it so finally stopped playing with making it and just bought it as well.. …

If it's true BP, it will say so, Otherwise it will list "replacement" …

Be Safe !!!

Somebody turned up a source that said Obatex was using willow charcoal, a good traditional ingredient.

I imagine that would be a rule here, but S. Africa? Who knows for sure...?

That may be true but once it crosses our border, it will comply with our laws.


Wait, that may not be true either …..

by volume

So the old adage, load BP only by volume, would especially apply to Obatek. And expect higher velocity as well.

I'm not sure why I would want to use the stuff, especially in a traditional side lock gun.

Except for fast lock time for flintlocks, perhaps..?

They specifically recommend loading by weight, just like the Sharps Rifle Co, ca 1880. But starting with half the charge weight as for other brands.

Never mind RSA, if it has been passed by the MLAIC, I'm betting it's the real thing.

Is there something wrong with the lock time of a flintlock ? Back in the 70s or so Don Davis use to write in a weekly publication, Shotgun World or something. He had high speed photos of a flintlock and a percussion lock going off. It wasn't humanly possible to tell the difference. A well tuned flint works just great.

weight v. volume.........percussion v. flint

I was not aware of the Sharps Co advice, but........could that specifically apply to cartridge guns? Seems like I've read that T/C (in their ML manuals) always recommended by volume?

If one ONLY loaded by volume, as done most frequently with a sidelock, how could you adapt to Obtex? Load only half the volume? My measures do not go low enough for half charges of some of my existing loads in certain calibers.

Not picking a fight, just confused.

Again, why would I want to use Obatex in a side lock? Is it cartridge gun intended?

flint & caps

Decided not to go down that path on this post, as it would sidetrack the discussion in all likelihood.

Of course Sharps was referring to their breechloaders, I just use the quote as a counterargument to the "grains volume" nonsense on the internet.

Obatex specifically recommends STARTING with half the usual Other Brand charge weight in muzzleloaders and adjusting to give desired performance. No reason you could not recalibrate your volume measure once you have gotten back where you started.
Bear in mind that this is in a country way off the usual trade routes and frequently embargoed for political philosophy. Domestic manufacture is a great advantage and just duplicating the old stuff was of no great importance.

I snorted when I read that. LOL

It would be great if they can get some to sell in the States too. I love getting 1000+ FPS from my 1858 in cap and ball mode and I reckon it would be good stuff also to charge the rounds for my .357 Vaquero.
