hollow point filled with potassium. upon contact with ttissue it explodes, is corrosive, extremely poisonous (causes cardiac arrest) and causes extreme pain by directly stimulating pain neurons. when you really want to frick upp your target.
I'm interested in ceramic penetrators.
Cheap, uses common materials, and extremely hard. Can be used either for a core material or as a nose material to different specific effects.

Stuff seems very promising.
It couldn't. It'd destroy your barrel if you tried and probably just break apart in the barrel afterwards.
In that pic the copper lower still functions as the driving band material.
would be nice if the whole process could be a single series of casting tools to make it cheap. I see in the ncbi paper they are using ceramic ball bearings as the tip and using a tungsten core for weight
Tungsten is heavy and hard, so it works well to drive the ceramic ball.
The problem of course is that its also a pain in the dick to work with on account of being so hard.
Ideally some kind of replacement could be found. That is reasonably hard, but primarily very heavy but non-toxic.
Tungsten tig electrode rods aren't super expensive. And pure tungsten rods arent bad to sharpen, you just need an alumina/diamond grinding wheel and itll make short work of it. You're probably thinking of tu gsten carbide, which is a b***h to work with. You can buy 3-5mm tungsten carbide drill blanks rather than alibaba fishing weights for more consistent products.

TIG welding tungsten is not the right kind of tungsten, I have tried.

Ideally some kind of replacement could be found. That is reasonably hard, but primarily very heavy but non-toxic.
There really isn't much out there that is of similar weight to tungsten that is also not even more horrendously expensive.
Tungsten might just be the easiest choice for the job of a 'hammer' here because everything else that could fill its roll is either super rare, toxic, or a combination of the two.
There was an anon who posted in one of these threads a while back, he had pictures of shooting (iirc) an ar500 target with a 9mm FMJ hollowpoint after he had placed a synthetic diamond in the hollowpoint cavity. There was apretty significant divot/mushrooming crater appearance to where the bullet had struck, in comparison to what a normal jhp would have done. Still not huge, it looked to be about 3mm across, maybe 1-1.5mm deep at the center. But it sparked some interest in what might happen if he were to do the same with some sort of high velocity projectile, e.g. a liberty civil defense schp at 2k+fps. And a discussion of how to forge synthetic ruby projectile cores or penetrator tips at home. If you look at buffmanrange's "obscure 9mm threat" test, DM91 (with an approx 3x12mm penetrator of tungsten carbide) penetrates polyethylene level 3 plates cleanly, even at a relatively low velocity of 1500fps. Would be neat to see a diy'd projectile tested with say a chunk of sparkplug ceramic or a small piece of synthetic ruby placed in front of a hardened steel penetrator in a polymer shell. Thanks for those links, btw.
>diy ruby
I've made some before, even posted on here about it. eventually trying to get lens quality rubys, but currently they are all amorphous. I want to use it for a gun sight for UV purposes. Never thought about using them specifically for bullets, and If I was to I would go with a THV style outside profile and solid inside.
The current plan is to build a machine out of a stick welder and inert chamber that: >spins crucible >pulls tungsten tip out at a rate of <16.4 thou a minute >reaches temperature hot enough to keep the melt molten >insulation enough that it doesn't require much power to maintain temps
Few other things but those are the most important.
Please document well. Always cool to see projects like this.
>FMJ hollowpoint

Being awake 24+hrs will really do a number on a dude. It was a JHP he posted pics of.
Assuming you're not lying, he was.
He literally posted pics in that thread. I'm not exaggerating the dimple that whatever he shot had left. Along with the typical lead rings around the impact site from a normal bullet. I'll see if I can dig up a screencap.

Would still need to add material to increase the mass, and wpuld need something, be it a copper base and driving band or ssome sort of coating to seal the lands ajd grooves of the barrel without stripping the rifling right out of it. Look up the belgian VBR "paralight" round. Capping it with a ceramic tip might be both easier and more in line wjth what the two research papers above showed to be effective.
My best idea is a custom 9x39 round
Take a 7.62x39 case, enlarge the head to fit a standard 9mm bullet, rebarrel an AK with a 9mm barrel or put a 7.62x39 bolt in a 9mm AR
???
Profit
Fit it with a 65grn 7N21 projectile to stay with the russian theme. Otherwise something like swedish m39b 9x19 projectiles are a good starting point. Its a gilding metal jacket with a very thick tip. Perhaps a similar design could be made with aluminum rather than steel, would likely be in the 70gr range, and just as unyielding. Aluminum oxide would be rough on barrels, so it might need to be a thou undersized and poly/powdercoated to seal against the barrel grooves.
Google what russian 7n21 is then. And what swedish m39b is. They are both 9mm projectiles.

Well if you ever do it please post pics and make a thread, I've been talking about loading 9x39 into 7.62 for years now but everyone has always said it's a stupid idea
The Russian 9x39 isn't the exact same diameter and everything as 9x19, so I think doing what I suggested would be alot easier in America since you can just use normal standard 9mm barrels and standard x39 bolts
>not just building something in .350legend
I dig 9x39 but .350 would be way cheaper to do with off the shelf components, barrels, brass, etc.
Melt silver solder inside hollowpoint, for werewolves.

Would it really be cheaper and easier though?
Isn't 350 kind of a meme round? There can't be that many barrels and bullets available for it at a reasonable price
7.62x39 and 9mm are both super common calibers with alot of cheap available components, you could drop a $120 x39 bolt in a $300 9mm AR upper and have it work

You'd have to get the chamber cut/reamed to fit 7.62/9x39 brass dimensions in addition to buying the upper. Likely peices it above just buying .350 legend brass, barrel/upper.
I'd like to try shoving a 9mm bullet into a 5.56 case. Cut the case down past the bottleneck, reshape it a little if necessary, and make a nice carbine round for use in short barrel ARs or something.
2.7mm Kolibri with DU core ammo, belted and loaded into a gatling gun the size of a 10/22 that can be fired from the shoulder.
Name a flaw. The DU gives it viable penetration and the ammo is so tiny that you could hold several thousand rounds in something smaller than a drum mag.
sorry for the error, fmj not jmj
I have no idea what you are talking about, but check these sweet bare tip new manufacturer x54R AP..

why not step it up to francium?
I like it when I don't get radiation poisoning lugging extremely radioactive bullets around all day
potassium is cheap and safe when sealed away from moisture.
Only a few grams of francium have ever been made, super unstable
Potassium doesn't explode on contact with tissue.

Not enough case capacity. I want a proprietary 2mm bottlenecked mach five cartridge.
A little bigger than 2mm, but I think it'll get the job done
They make .17 caliber rounds that get to 5kfps way way smaller than that

What the frick
Any way a layman can make his own tracer rounds? Preferably without creating mustard gas or burning his house down in the process?
Instead of AP relying on kinetic energy, would it be possible to create small caliber HEAT ammunition?
Theres a point of diminishing returns as you decrease diameter.
But has it been tried against body armor? How would ceramic materials react to HEAT compared to steel?
