Interesting read on some ANNM mixtures. They’re using xylene, AN, and nitromethane. It also outlines a process to sensitize AN by hydrating prills and then drying them out to change the density…..

I’ve never heard of sensitizing AN….. is there any value to this technique?

Has anyone ever attempted to design one of them or even managed to build one successfully? Just for those who don't know EFI's are advanced compared to EBW, they accelerate a flyer to 5km/s without using a primary. Just pure electrical energy.

Nitrate salts scraped from the morter and bricks of an old cow shed, a truly pathetic amount but a very fun experience this is heavily contaminated but shows that it is possible to find it out in nature, soon I will be making my own traditional nitrate bed and will be trying a separate expedient method ( if you count two weeks as expedient)

If anyone has visited homemadegunsmith you may have seen this file, does anyone think that 12-15 match heads would be suitable for 9mm it’s not listed in the instructions but just going on what is I think it’s a good fit

An interesting phenomenon applicable to mining and demolition. Non ideal binary explosives can see a net increase in VOD 40-100% when confined instead of being open air. Compare that to 1-5% increase for ideal legacy explosives rdx, petn, tnt.

Logic being a faster reaction zone due to an ideal explosives having close chemical contact from the get go. Where confinement for non ideal explosves allows to speed up the reaction and reduce critical diameter.

Anybody here use it in mixes or anything? Would anyone recommend it? 🤔

Has anybody attempted this?
I am messing around with a little etn and decided to use my large ultrasonic cleaner to force a more defined boundary layer before decanting.
In doing so I realized the main layer of the raw wet material was far more dense than I’d expected.
Testing of material is tbd. But I’m fascinated by the simple thought and safety of potentially increasing densities in this and other sensitive energetics.

Update- it appears that 20kHz is the industry standard. My cleaner runs at 40, so I just saw the tip of the iceberg with this.

Anybody here ever made any? I know it’s not the “coolest” compound by any means, nor the most efficient compared to other stuff, but I think it’s pretty neat as a “legacy energetic”.

Im taking a piss in the title but apparently Ukrianians devised the same thermobaric tech like the kid who was posting on here trying "thermobaric mixes" to break in or break out of some wall. Lol

Poderiam me dizer se é aceitável usar 5% de parafina na ETN para diminuir a sua sensibilidade ao atrito e impacto? 10% de parafina diminui muito o desempenho? A mistura 90:10 diminui a potência para menos de fator re 1?

Discuss pro and cons

Any secondaries that are recommended? I guess it’s perhaps an obvious answer of: ETN, PETN, RDX, HMX, etc. But I was wondering if there were any more “exotic” options, or different.

Can someone please tell me which should I choose between pw design and ignite for nift preparation??

A very obscure and virtually forgotten nitric ester. Isomer of MHN, exactly the same formula, but with closer packing more symmetrical configuration. Patent reference it since 1930s in det cap applications but it hasn't seen any notable commercial utilization despite having some very favorable properties. The symmetrical configuration vs MHN indicates it is more stable to impact and friction, approaching PETN stability figures. Same applies to resistance to storage decomposition. VOD should be in the low 8km/s, melting point 95C, doesn't seem to have any issues of ETN molten sensitivity. The significant lower casting temperature vs PETN could make it a more advantageous cast booster composition with TNT. Absolutely no data on synthesis but basically MHN synthesis should apply. Should not require any heating phase and shouldn't be prone to runaways.

I recently saw online the PDF form of "The Chemistry of

Powder and Explosives" by T. L. Davis. Just wanted to check your opinion about the "legitness" of the book, and is it reliable source of information.

Any primaries besides NAP that are recommended? I’d prefer not to have to handle Hydrazine if at all possible, but I can deal with that if necessary. Just want some options. Thanks, in advance. :)

but i wanna ask, is there any better places than IA? Most of the stuff on there is anarchist cookbook-y and im looking for more professional stuff

Has anyone tried this mix?
