Is DIY Smokeless powder possible?

  • 🐕 I am attempting to get the site runnning as fast as possible. If you are experiencing slow page load times, please report it.
Nigger did you just join two days ago to whine about telling home chemists to not make nitrated propellants?
Long time lurker, you could've replied to me directly. I'm not "whining" but instead of posting news articles of people getting 5 finger discounts and face removals or something you're telling them to make a crossbow like that will convince anyone at all. At least black powder would be a good stepping stone.
 
"I reasonably want to make smokeless powders (and primers) myself, also in a STHF situation"
>There are NO known ways to safely manufacture such propellants and especially the primers, even if you don't give a shit about the law, because the logistical and technical overhead will kill you
"YEAH WELL THERE MUST BE SOME WAY OR SOMETHING
>I've listed out in detail what the problems are for you, what kind of equipment and space and safety measures you need, and it should be obvious that without million dollar budgets for specialized equipment, a mastery of chemical engineering to use it, land for your blast bunkers that dry and age the product, and supply lines of chemicals that WILL NOT EXIST in a STHF situation, you either won't get off the ground, or will blow your face off
"Post news articles of people getting face lifts and carpel tunnel removal or I won't believe you"
OK then.

Also, I DID say black powder was a good idea. A great one, even. I even discussed electric ignition if you didn't want to lean on caps (might be hard to make in SHTF), flintlock, or matchlock!

"Niggers who refuse to accept no get shit done"

I don’t deny that, in theory, a DIY propellant (or even primers) could be made safe and proof-tested.

The problem is that the path from “gram scale and ice bath” to “reliable nitrogen-based propellant” is a stinkditch full of ways to kill yourself. Fuck it, let's go ditch-diving!
  • Residual acid stuck in voids or fibers fucks you extremely fucking hard. Sulfuric or Nitric acid eats the ester, makes heat and NOx, runaway autocalysis -> you get Sig Sauered.
  • pH fuckups BEYOND the above can fuck with metal casings. Cu/Zn in brass casings catalyze below a pH of 6.5.
  • The outside can read dry even if the core is over 60C and exothermic. Vapors + Hotspots = 🤯
  • Grain pores/micro voids can create deflagration to detonation transitions that are also less than 41% safe.
  • Uneven moisture changes burn rate, splitting casings or giving you facial piercings
  • Wrong plasticizer or bad plasticizer distribution? Pick something from above and enjoy your facial.
  • Stabilizer done wrong? Self oxidizing in storage, pressure builds, fun times.
  • Particle size correct, and consistent enough? Look carefully at the propellant grains you can buy bulk for home loads. Little tubes.
  • Rolling, cutting, or pressing dry propellant can raise impact sensitivity.
  • Propellant dust in the air is flammable. Home vent hoods can sometimes pull that right through motors. People who don't have one get facials.
  • Off gassing propellant can attack things it's stored in.
  • If you want to do just straight guncotton, you still need to have an overabundance of water, tons of sulfuric acid, some kind of alkaline wash/dip, ways to wet-pulverize, filter, and some way to press to ~150-300MPa to remove air pockets. YOU DO NOT WANT DETONATION
  • Unplasticized guncotton that isn't kept wet can blow up pretty fucking easily. So, you have to make colloid or plasticize or whatever.
Walter White could do this with seven-figure budgets and a clandestine plant. You, post-SHTF or otherwise, cannot

Cap-and-ball revolvers are going to work as long as we have primers, and black powder long guns can work without.

I'm going to recommend air guns for as long as you can replace the seals. Lewis and Clark carried Girardoni air rifles, Austrian sharpshooters did from 1787 to 1806, and you can see people take hogs with modern ones. These are so stupidly slept on but whatever, and they go back to the late 16th century.

Bows, cross or otherwise, are no joke, and are always worth learning to use.

But what the fuck do I know? People who likely don't even grasp the primary synthesis, never mind washing and neutralization, pressing, stabilization, proof testing, etc, think they can just make a 1:1 replacement for propellant.

If anyone wants to try, stream it, please :story:
 
I did a little more autistic thinking I feel like sharing.

Air rifles can work with oiled leather seals and hand pumps. People really need to stop sleeping on this shit. Not a bad idea for SHTF at all. You don't even need an ATF check to buy one, and they're easily legally silenced so you can shoot without ear pro!

Black powder doesn't even need sulfur, but it helps. Sulfur can be hard to come by after SHTF, but hey. Bows never went away for a reason, same with crossbows. Don't knock the classics.

I did come up with a usefully retarded idea: rocket candy "bolter guns". Potash isn't that hard to get, same with sugar. If there's RC left in the bolt when it smacks into someone, if it's fragile enough to shatter or break, you just dumped 900F/500C caramel-napalm on your target in addition to the terminal energy on target. Not bad. Fucking batshit. Don't fucking do this.

As far as propellants go, you're going to run into issues with supply lines in post SHTF, FULL STOP, and even if you somehow had a magic jar that pissed out chemicals for you, you're still dealing with all that shit I said above (acid spots, voids, grain shit), proof testing (EVERY BATCH IS DIFFERENT) and needing a danger shed or bunker full of kill-you-or-poison-your-land chemicals to do it.

On top of it all, assuming you got here, you need to either sell your spent chemicals (nitrogen waste) to farmers, use it yourself, use a river to dispose of it for you (and piss off people downstream), or make a denitrification trench. If you dump it in concentration on on land you're farming you'll over nitrate it or leech out elements by dropping PH too low.

There are multiple steps that are beyond someone without a plant and a team of autists that will invariably kill someone who isn't doing this in a plant. You need to carefully test the propellant, explosively, with instruments, before filling to see if you need to go up or down with batch variations, or always under fill your loads. You need a literally industrial supply of clean water, two strong pure acids, several solvents, inert reactor vessels, mixers, hydropulpers, presses, and bunkers/barns separated by berms far from anything valuable.

If I could think of any chemical you could safely squeeze through a pasta press I'd just fucking tell you, but there isn't one. Do some fucking rows or chinups, mix potash with charcoal, or pump a tank.
