OP of original threrad here
bringing this shit back to life
does this not interest anyone else?
>>29875976
Eh, this is beyond esoteric for most and the chemistry involved with getting even further into gets outright terrifying given how fast lead styphanate can and will fuck you up and how hard and expensive tetracene is to get.
>>29876105
To be fair, Hamilton himself said that tetracene was made in house and gives thorough instructions for synthisis using far cheaper base ingrediants. Though I wouldn't reccomend anyone without some very extensive experinace be fucking about with priming compounds of all things.
I'd be up to making a progressive draw die for 9mm or something just to do it. Hard part is figuring out a way to get the extraction groove cut in an efficient manner.
>>29875732
Guy who said he'd keep it alive... sorry
>>29877595
It seems to be made via the same process as the initial draws with no cutting.
>>29873223
mediafire never works for me, can you MEGA upload?
>>29878418
That is true of rimmes cases. Cases that have no rim have it cut as far as I can tell via all of the videos and shit I've watched.
>>29879127
I've tried in the past and it never worked properly.

First time using MEGA, is this right?
>>29879289
Wait, here it is.

>>29879272
Mega or media fire?
>>29879312
Considering the stuff is linked to a Mediafire account I made in 2011 for the Ultra Do/k/ument project I think it's safe to say I can't get Mega to work.
Also found where I had stored these. Variations of the Eley prime system. Several more I;m still looking for.

>>29879377
I'm chemically illiterate but from what I can understand it still involves lead styphnate and tetracene, just the method used makes it easier to mix instead of having to start out of lead styphnate to begin with, it uses lead monoxide and apparently very pure styphnic acid is needed or the mix doesn't work right.
Am I missing something or is this just a safer way to manufacture the same product?
>>29879830
It's mixing dry ingredients then dosing them into the case. Once in the water is added and the mix undergoes a reaction to make lead styphnate in the case itself. It's incredibly safer compared to the wet rpiming.
>>29879846
Ah, I missed the part where the water is dosed with tetrazene. Surprised they managed to get a patent for this, is it for the compound, method or machinery?
>>29879909
My guess is method.
The priming mix was already established in the literature as was the machinery.
The tetracene can be dry mixed as well. You simply need the water to activate the styphnic acid/ lead oxie reaction.
>>29879967
Tetracene is very impact sensitive, m8. The literature says to mix it in an unspecified amount of water to desensitize it and then dose that into the lead monoxide and ground glass.
>>29880008
If you read all the patent info they specifiaclly mention that at the concentrations present in the dry mix it poses no hazrd. it has been buffered by the other more inert components.
>>29880107
On mobile so it's hard to read the darn double columns. So is there anything about how pure the styphnic acid needs to be? They say 'pure' but I'm not sure what that means in an industry context.
>>29880143
Relatively pure. There is mention commercial grade does not work well for the previous methods but this mehtod would avoid that.
Any help with this it's a .50 Cal but I don't know what the markings mean

Mostly bump , however
I have many a time thought about this .
The feasibility has always seems a but beyond all but the most determined diy-er
Kinda like what's the point , I mean how far do you take it . Your not going to mine and the smelt ore from scratch .
For all this talk about primers look in Chlorate based formulas , it's simple and has been done
Cast Boolits forum has a whole thread on making primers , they have done just about everything one could think of when it comes to reloading .
I have never come across someone who has actually made their own cases , but that doesn't mean it has not been done
Don't get me wrong , I hope you succeed , but it's a lot of time and money and learning to get their
>>29882212
>Cast Boolits forum has a whole thread on making primers , they have done just about everything one could think of when it comes to reloading .
Link to thread? Have they done anything with swaging jacketed bullets or alternatives to lead cores? I think it'd be rather helpful.
>>29882212
Chlorate primers are easier to make but at the cost of being corrosive. Using the Eley prime system and following synthesis of various harder to get components on Frost's instructions.
Following the calculations in the previous thread it should entirely be possible to do so with a 20 ton press, though sourcing dies would be a matter of fabrication.
It could be possible to form cases in tact in the same way that copper plumbing fittings are made - From a slug injected with high pressure water into a mold. The excess is trimmed off.
I once read about a company that made cartridge cases for some obscure calibers by just cutting the fucking things on a lathe. I imagine that would be more than adequate to get a straight or slightly tapered case in a few operations. You could give it a neck or whatnot with some dies afterwards.
>>29882618
I used to reload for .38spl and .380 ACP using just armstrong's mix for primer compound. It's surprisingly effective in a pinch.
>>29882620
Necking down a turned case is never recommended. The grain structure of the brass means it will crack much easier.
>>29882751
I don't imagine that you'd use a turned case in anything but the most desperate possible situation anyways, but it's much better suited for pistol cartridges. Easier to control the thickness.
>>29882706
Been there and done that too. Did you have any problems with the awful residue it leaves behind?
>>29882868
Turned cases are quite common in the blackpowder crowd and with the guys firng very large rifles.
>>29882881
Yeah, they don't really have much of a choice. There isn't really much in the way of parent cases for them to reform or anything.
>>29882751
>The grain structure of the brass means it will crack much easier.
Couldn't you solve that with hammer forging, like they do to receivers?
Wouldn't this be reasonably feasible in the garage?
>>29876105
just use perchlorate like the rest of us peasants
>>29883746
Is it even that much easier to make than just making stypnic acid and tetrazene?
>>29883779

>>29883409
I own several factories manufacturing casings and primers; if you want to ask me anything.
See attached, my transfer press tooling used to make 9mm.
I also manufacture 100 million primed 22 casings per month and boxer+berdan primers.
>>29883978
Why is there no 25-70 ammo?
>>29883978
Yuo willing to post time stamped pictures or any other proof this time?
>>29883978
>berdan primers
How available are these in the US? part of the reason I never got into surplus rifles was the realization that the cheap Berdan primed stuff would eventually dry up.
Is the demand for .22 waning at all?
>>29883978
I remember you. Still refusing to hire anyone from 4chan?
How much in-house toolmaking do you do? How much do you contract out?
>>29883978
Why are lead free primers so damn impossible to find?
All I want to do is shoot some primer only wax bullets in my basement :(
>>29884032
Because the low volume, its hard for anyone to justify production with tooling change over.
>>29884043
I'm at home, but can post some more equipment pics/videos with the watermarks.
>>29884079
Non-existant in the USA. I'm importing them to load steel case pull down casings which then go back overseas for customers.
Demand for 22 is lessened from distributors/investors, but still selling everything that can be made. But prices are coming down, as more manufacturers get their lines up prices will drop.
>>29884091
90% all tooling in house. Some crazy stuff we send out for EDM. I got to stay anonymous.
>>29884128
Mainly because scheduling in production when 95% of orders are for standard primers.
>>29883978
Steelcase 12ga shells yes or no?
bumperango
>>29873223
I'm going to bump one more time before bed
I would like to know more about the metallurgy , surrounding this topic .
Would steel be more suited for turning cases ?
>>29884909
World market is flooded with hull manufacturers. We use pre-primed low-brass hulls from Spain, made from actual brass.
Full length steel casings are only a Russian thing, and are not economical. We could although do the whole shell on a single transfer press if we wanted too.
