Theoretical Bullet for Sci-fi

Any context for why a ferrofluid would be needed?

Why can't the ferrofluid be inside a metal jacket?

>ferrofluid projectile

JUST USE MAGNETIC METAL GLASS IF YOU WANT TO SOUND TECHNOBABBLY YOU FUCKING RETARD

Just put your fluid inside a tungsten sabot. The sabot absorbs all the heat, peels off and the fluid should form a very aerodynamic tear drop.

Partially for artistic reasons, the title is Black Jacket Bullet. But the other reason is a liquid bullet to help eliminate ballistic evidence that comes with a solid slug.

That sounds like it could be an ideal solution. I'll have to look into the science behind it to make sure it's what I need, but it sounds like it'll be ideal.

you could always go the Halo route and make the gun project magnetic fields/have a projecting core that keeps the fluid together and provides some guidance or tracking

A container that is shed whenever the electromagnet in the bullet activates so you can do neat things with the ferrofluid.

I mean, you already have electronics in the bullet if you're going to be manipulating a ferrofluid on its surface.

Why not just have its casing dissolve or shed with the activation of the ferrofluid?

You're presumably shaping it into something cool midair and then it should harden before impact?

no need to be such a sassy molassey, anon :^)

A glob of liquid doesn't have the cohesion to work as a bullet, it'll be torn apart by wind drag, and it'll refuse to be spin stabilised while we're at it.

Why not just have it deliver something that burns up on impact with the target instead of using the fluid? Like the bullet hits deforms and it starts a primer that burns up some mg or something i don't know. I'm just imagining it not being stable at all because it's a fluid.

Figure out how to keep Gallium bullets cooled during firing. Gallium turns to a liquid at 29.8°C and seeing as how body temp is 37°C....

Just use "nanomachines, son".
Ferrofluid that has nanomachines get fed into the chamber, where the desired bullet shape and other info get fed to the nanomachines, which then take shape before leaving the barrel.
Want to shoot a bunch of needle shaped flechettes? sure why not.
Just one solid bullet? coming right up.
APFSDS? can do.
All your projectile needs in a one-stop-shop solution.

maybe some kind of fancy pants technomagic core that is electromagnetically charged during the projectiles acceleration and holds the ferrofluid to itself? upon contact with a target the increased amount of force could cause it to shear off and fragment.

The core could be fragile enough to do the same or you could have it stay intact and use it as a clue.

to be fair, it is a scifi novel so you can say that we found some magic 2150 bullshit way to freeze it and all that

Not to be that guy, but isn't it going to be a significant forensic marker when the dead dude has ferrofluid in his wounds?

you're a "writer" just make something up. it's called creativity.
