How is the best way to make ammonium nitrate? Is urea nitrate an impact explosive? If so are any of these able to act as a makeshift primer? If not do you know of an explosive easily manufacturable that can serve as a impact explosive? The main reason I want to know this is because I know how to make an improvised powder but not an improvised primer and wish to know how to reload a spent casing with easily improvised materials.

you asked
"How is the best way to make ammonium nitrate?"
oh my god you ask this and your a moderator
sh!t you can buy it as fertilizer at 50kg for $32
or get it from instant cold packs
why would you want to make it when it's so easy to get once you have it it's easy to purify anyway

I mean from stuff found for the most part in nature.

Alan, Ammonium nitrate is insensitive to detonation by impact, Better lay in some factory made primers or percussion caps if your'e concerned about long term survival in case of anarchy or whatever. Mercury fulminate with potassium chlorate added can be used to reload primers, But the case can only be used once if ths is done, The byproducts of combustion weaken the brass.
I've seen strike anywhere match tips used to reload primers,But I don't know how reliable the primers would be.
Calcium nitrate can be treated with ammonium sulfate, Giving ammonium nitrate and calcium sulfate as a byproduct.
As calcium nitrate is found in nature, It is a universally available material, And reaction with sodium or potasium carbonates will give sodium or potassium nitrate, Respectively.

damn I wonder what that chemicle is It is ammonium somthing. say It in the cookbook and I cross refrenced it with the big book of mischeif, which is a more reliable source. IT is an impact sensitive explosive, I hope urea nitrate is it was my first choice for an impact sensitive explosive.

Alan, I think what your'e referring to is ammonium nitrogen tri-iodide, A _CONTACT!_ explosive, Not suitable for gun primers or anything else. You'd best read some more literature before trying anything in the BBOM for your own sake. Be safe, Not sorry, CrAzEdByTcH

To the reader: I checked out the BBOM and PMJB, As well as the Anarchist cookbook, I wouldn't try _ANY_ of the formulas in those manuals. Pray for Mr. Smithee if he does. CrAzEd (But not stupid)ByTcH

I wouldnt do anything from the anarchists cook book, the bbom is a slightly more reputable source though. Idealy Id like to find it in an army manuel, yes it was amonium nitrogen I still want to know if urea nitrate would work.

Urea nitrate won't make a primer, Alan, But I have some formulas for primers,you can get an idea from them what makes a good primer mixture. (For reference only, I've never made primers, And have no other information or instrutons.) #1 Mercury fulminate 40%
Antimony sulfide 20%
Barium nitrate 10%
Pb TNR 30%
Pb TNR is lead trinitroresorcinolate.

#2 Pb azide 5 parts
Cu Silicide 10 parts
BaNo3 15 parts
Tetrazine 15 parts
This one contains Lead Azide, And must be kept from contact with copper or brass. REACTIVITY HAZARD

#3 Mercury fulminate 90#
Potassium chlorate 10#

All of the above are too sensitive for any amateur to attempt self production, And are provided as study materials only.

You can see what you're up against, Alan, I've never even heard of some of the required chemicals, and the actual prouction methods are trade secrets.

Now you can see why anyone with experience reloading ammunition will advise buying all the required items at a gun store.
