You've never seen a gun in your life, have you?
That question aside, there's literally no reason to ever chamber a weapon in 1.85mm, for any purpose, ever. Your round will achieve great armor penetration, before exiting the target with no lasting damage. If the tiny projectile isn't deflected by things like blades of grass or raindrops first, that is. Or, to better explain, .22 LR is a better military cartridge than what you're proposing.

I know what you mean, in fact, the project is a bit 'too virtuous, but there are other aspects to consider, before you jump to conclusions.
A .22LR traveling at 320 m / s with a power of 133 J.
While a 1,85x66mm travels to 1350 m / s with a power of 1822 J.
Just think of the formula E = mc2
According to some calculations, the kinetic power of the indenter is ok, if it enhances the propellant. Everything depends on the tip of an object, for example if you use a system FTX Flex Tip EXspanding, placed inside a hollow nose cone, the penetrating effect, serves as a power to destroy tissues internally. In other words, it apparently has the effect of a kinetic penetrator, with some internal improvements, ie a hollow tip. At that speed a cavity like that can create harmful effects. If this were not enough, you could shoot another burst, because in the end, in the magazine, are placed many more bullets weapon standard.

I have no idea what you're saying. I take it english is not your first language.
In any case, you're missing the point. The projectile has too much kinetic energy, while having an incredibly thin projectile. This will lead to an affect known as "icepicking" where the projectile will overpenetrate and do little lasting damage because of how fast it's going. While yes, your round might have a special projectile, a 1.85mm hollowpoint isn't going to be very effective on account of being tiny. That, of course, is on the off chance the round slows down enough for the round to expand inside the target. There's a reason micro-calibers and flechettes never caught on.

If it were a higher caliber I could agree with you, but it is a dart very light, and hollow point, it can be slowed down a lot.
Over 340 m / s (supersonic speed) a bullet, creates forward to if, the Mach cone and the relative shockwave, all this if unable to penetrate, protections, garments and skin. Much energy, falls after this series of obstacles. (Consider the little weight) Once the projectile (equipped with aerodynamic cap FTX) impact with an obstacle, the cap dissolves, leaving the penetrator hollow-point advance in the rest of the target. The bare hollow point projectile will penetrate the defense alone and at that point the resistance of the materials encountered, halve large part of its energy (without excluding bones). Within the tissues as it will have an explosive effect.
There is still no effective mathematical formula to figure out the best stopping power.
As for the program "flechettes", it was abandoned due to lack of funds and advanced technologies, not only for their inefficiency, it is more economical to use materials such as copper and lead which use small penetrators metal more dense. it differs from my project, being only simple darts.

You're not getting it.
A projectile kills through loss of brain function, not through energy. Projectiles achieve this by stemming flow of oxygenated blood to the brain, lowering blood pressure and starving the brain of oxygen, thus killing the target. The other method is simply to sufficiently damage or destroy the brain and/or central nervous system, so as to incapacitate the target; no need to starve the brain of oxygen then, as it is already dead or unable to relay signals. Your round however, is too small to create a large enough wound cavity to be fatal.
Stopping power is a bit of a misnomer, and an oversimplification. The proper term is "terminal effectiveness" and is related to a projectile's ability to cause a lasting wound cavity. It's also worth noting that economic concerns didn't kill the flechette, being hilariously ineffective did.

This concernes only sectional density, but if the projectile was a lot ductile it would get deformed. Also, the lenght of the bullet is not specified, only the propellent one is (66mm). I could shorten the bullet, thus increasing the energy relase on or in a human body.
The S.P is different from the harmfulness and death from internal bleeding. You can stop an enemy even without Killing him, it's the gauge neutralization power.

You clearly have no idea what you're talking about.
I'm done here.

You really like bullpups, don't you?
Anyway, it's nice!
