Please , now i try make ammunition, now I try to replace nitrocelulose by anfo, will be that can work?
please help :)

There's no way that will work, ANFO is not even really flammable.

Regular old black powder is the most effective, easiest and safest propellant that I know of for an amatuer to make.

Making black powder with a ball mill can be quite dangerous, I recommend milling the ingredients seperately.

Ammonpulver was a AN-based propellant ─ google it?

From totse.com:
"AP was developed in the late 1880s as a replacement for black powder. It
is an intimate mixture of 85 percent ammonium nitrate and 15 percent char-
coal. ... It was extremly powerful, being on a par with double-based powders containing 30 percent nitroglycerine, and was virtually smokeless and flashless. ... when it was heated to moderate temperatures (32.1C), a change in the crystalline structure occured, causing the powder grains to crumble.
This would cause a drastic increase in the chamber pressure of guns using
this propellant, often causing burst tubes."
. Doesn't sound like DIY material to me.

In video from link (and from text) I see very modest living conditions. I recommend start your education on classic black powder. If is you needed target shooting or hunting of meat. For this purpose is black powder best. Almost Non hygroscopic. Ammonium nitrate is very hygroscopic always. In any mix. And especially during preparation. Dr.

Thank you by the help liptakov,OneEyedPyro and hissingnoise , i try black powder, yous suggest me the right ammount , i will go put 20% in the litttlo piece tube? and i have doubs about the bullet projectle?

This reminds me of the recent fiasco with ammonium nitrate in airbags. It seems this problem has been around for a long time.

It appears that ammonpulver will not fire in a rifle cartridge with the primer alone. A small booster charge of conventional propellant was required. Once that was sorted, it performed well.

don't try to replace nitrocellulose by ANFO, it will blow your shit up
