DIY Black Powder -- just getting my feet wet

[shaman]

I am picking up a Brown Bess later today. I've been firing smokepoles for nearly 40 years; this is my first flinter.

I have been running through the 240+ page thread on BP. I had some questions:

1) What is the best beginner's method that requires the least initial outlay and gives the best results. Is it the CIA method?
2) If I jump in with both feet, is Fly still making those puck makers?
3) For a Brown Bess, is there any special considerations when making BP. I assume a 2F-3F final product suffices?

Yes, that's the thread I was meaning.

Welcome to the world of us Powder Monkeys.
I am sure that lots of members will help you get started

BTW: I nearly got banned from The Muzzleloaders Forum for mentioning that thread in a post. Yikes! This must be really subversive stuff. Should I be wearing my MAGA hat and a yellow vest when I make my own BP?

They won't ban you right off. They'll give a warning first and then put you in time out for awhile if happens again. I don't know why they get their nickers in a bind over it. It's not like it is illegal and it's becoming more and more a necessity. You can PM someone there about it and not get in trouble.

If you are just starting out making your own then yes the CIA method is a good starting point, especially for the main charge. I would recommend you still try to fine a can of commercial BP for the priming pan. I have been making my own for 30 odd years and closely to the CIA method , with flinters I still use commercial in the pan.
If you can introduce a ball mill for milling the charcoal and sulphur before adding to the dissolved Kno3 you will increase the consistency of the shot. I also just use stale urine so ingredients are just Kno3,Charcoal,sulphur, stale urine and nothing else. Charcoal is probably the most important factor, I use Willow.
Enjoy your new hobby.

You don't add something as a binder?

Nope just what I wrote.

One of the most popular (possibly THE most popular) method is so-called "screen powder" - biggest expense would be a ball mill (a $50 rock tumbler from Harbor Freight would work) - I recommend this video from Brushhippie -

A significant problem with the "CIA" method is that you inevitably lose some of your potassium nitrate, dissolved into the water/alcohol (which is discarded).

Since you have a Brown Bess, it's worth noting that compressing BP into a puck was not developed until the 1800s.... screen powder might be a touch more authentic.

Interesting that I have never discarded any liquid from manufacturing powder. I use 450ml of stale urine to 750 grams Kno3 , heat to a simmer and dissolve the Kno3 then add the other 2 ingredients. As it cools it solidifies and no moisture is lost. I do think some add too much moisture.

Drat! That was part II, and part I is missing. That looks really interesting.

Apparently we have some confusion over the “CIA” method mentioned by the OP. The CIA method I’m familiar with entails boiling the ingredients in water, then dumping the slurry into ice-cold alcohol, and then separating the solid material from the liquid. It is described in Von Maltitz’s book (see page 97 in the book, page 98 in the PDF file) -

The process you describe sounds more like another type of “precipitation” method, supposedly used by the Chinese over 1000 years ago (Von Maltitz did not specify the type of liquid… Water? Urine?). See page 154 in the book, page 155 in the PDF file).
I agree, this so-called “Cool Marble” method does not result in any loss of potassium nitrate.

I think Part I got lost when Brushhippie moved from Youtube to Gunstreamer.

You are probably right. The only reference I had Seen to the CIA method was a video on youtube. If you search black powder the CIA way it should come up. Thanks for adding the PDF, that's going to make some interesting reading.

ofitg, an interesting fact you mentioned about pucks. Do you know if civil war powder was “pucked”? That would certainly make a big difference in loads then and now

What I’ve read indicates that compressing BP into “pucks” or “cakes” as we know them today (density 1.7 gm/cc) was not feasible on a “production scale” until the invention of the hydraulic press, around 1800.

https://firearmshistory.blogspot.com...-pressing.html

This U.S. Ordnance Manual of 1850 mentions hydraulic presses (page 215 of the book, page 244 of the PDF file), along with a couple other less effective methods. It sounds like U.S. arsenals may have been upgrading to hydraulic presses at that time -

I think it’s safe to say that at least some – perhaps most – of the BP used during the 1860s war was the “modern” form that we still buy today.
However, some of the Confederate powder manufacturers took shortcuts, trying to keep up with the demand. One of the “innovations” practiced at the powder house in Augusta, GA, was to bypass the hydraulic presses altogether.

That brings up the next question. I wonder what the difference in velocity of a given amount of powder, pucked vs. non-pucked would be. Obviously, the amount of available energy is the same, but I suspect the non-pucked would be slower. Are you able to quantify the difference in any particular caliber and load?

[LAGS]

The FPS is faster with the corned powder.
But ,
If you shoot say 50 grains by Weight of both screened and corned powder , the FPS is almost the same.
But if you shoot the two powders by Volume instead.
The corned powder weighs more per the same volume of screened.
So say you shoot 50 grain load of each by volume.
Then the corned will give more FPS because it is actually more weight.
Now this is my opinion from past testing.
But others may see it different.
