I tried to translate it into my language, but it wasn't good. Anyone who reads the .pdf, if you could paste the section that deals with maximum pressure here, I would be very grateful.

Would agricultural grade ammonium nitrate work? It is typically made up of 70% ammonium nitrate and 30% ammonium sulfate...with some other impurities.

If you need high density, use a maximum 2-inch die, and work one disk at a time. Little dust and almost no water. The disc must be no more than 3mm thick. I do it this way and I get up to 2g/cc......

Good job!

.40 caliber = 40 grains BP.
.50 caliber = 50 grains BP.
Its is basic.

I use a PVC mold. And I have no problem.

Studying here... Cellulose and hydrochloric or sulfuric acid cause the hydrolysis of cellulose. creating Nanocellulose. Something old that is being rediscovered as a fantastic material. Today it...

Interesting...I'll follow your Mustang efforts! One thing I found strange is that hydro cellulose seems to be the only fuel in the mixture, but the quantity seems to be very little. Another thing I...

It is not necessary to use dextrin, not even in Golden powder, Crimson powder and any other that uses potassium nitrate and ascorbic acid as main ingredients, because after cooking, when it cools the...

use golden powder on the bottom and smokeless on top. It is the duplex load that works best... including for shooting with rifles, like .308, 30-06, etc. These duplex loads burn very clean...you'll...

CBC markets in the US under the name Magtech. Currently it also acquired S&B. CBC (Companhia Brasileira de Cartuchos) became the world's largest ammunition manufacturer. Which is part of the same...

Friend, this information of yours is very important, it makes all the difference in understanding. Maximum 36,000psi and stops burning when it exceeds this value. Could you provide the source of...

Yes I believe. The author made another .22 gun, but with flint... and in this arrangement it seems he couldn't achieve more than 2,500fps.

As soon as I do a test, I leave some of the powder on a plate on the table and observe. So I can observe the hygroscopic potential of each one and I discard the worst ones.

Today I watched a video on YouTube of a guy who made a .22 cal muzzleloader, with just an 18" barrel. It says in the video that he reached up to 3,200 fps with the lightest bullets.

Yes... some mixtures become more or less hygroscopic, dry powder has to be well packed, preferably with silica. I always prefer to make small batches to use within a month at most. I still have a...

Couldn't you use a sieve to put the powder in?

Magtech=CBC/Taurus.
CBC... Companhia Brasileira de Cartuchos.

Your formula didn't give me confidence. Are you really using ammonium nitrate? Do you know that it is very hygroscopic? You would make this powder very good if instead of ammonium nitrate, it was...

One thing at a time. First we find out how fast we can and then how fast accurately. Smokeless powder also faces these issues and to this day the development continues. Why should we end the issue...

25-20 ...I already said here that I would love to have that caliber! Make powder especially for him...press very thin discs, 2 or 3mm and very little water. This way I guarantee you can get up to...

Lags, good solution you adopted. Here I prefer eppendorf tubes with heavy loads. They are practical to use and guarantee accuracy.

The idea of ​​black powder pellets is a good one, it makes things much easier. The secret is to make the pellet with one or more holes. When the outer layer burns, its area decreases and therefore...

I'm sorry, this time the message was in my language. Thank you Mustang, for the translation.

Quanto mais clorato ou perclorato, mais forte será o pó.
