Forget powder and bullets, this is the future of guns
No recoil
No inaccuracy
No noise
And the best:
NO FUCKING ATF REGULATIONS
Why aren't you engineering coilguns guys
>>30331362
>Why aren't you engineering coilguns guys
No room-temperature superconductors.

Stopped reading your stupidity here.
Can't wait for the end of summer.
>No recoil
Newton says hi.
>No inaccuracy
...right.
>No noise
For a given value of "none". Just hope subsonic gets the job done.
>NO FUCKING ATF REGULATIONS
That will last until these get somewhat kinda sorta viable, and no longer.
>>30331448
He got a valid point, though.
What are the main obstacles to hand-held coilgun, beside compact enough superconductor ?
>>30331448
He probably wanted to say that recoil is negligible in comparaison of a classic firearm
>>30331489
>besides compact enough superconductor
Those are decades away. Maybe a century away. Maybe they don't even exist. And we don't know the theory on how to find them, even if they do exist.
Also, if you do without superconductors, you still need a fast-discharge high-density energy source; which doesn't exist in small enough form for handheld weapons either.
But couldn't the gun in the vidya related be improved to make it more powerful ?
>>30331362
Needs explosive ammo for some chemical killpower to make up for the lack of velocity and therefore lack of physical trauma.
Like a mini grenade launcher so that the guass developers can just focus on getting the range to a respectable number.
>>30331489
>He got a valid point, though.
That's future.
I'm a visionary.
Future people will mock us when they will see our ar15s an Aks
>>30331523
We have that very same discussion every two weeks. Recoil is function of the mass, and square of the velocity of the projectile, no matter the way you throw it.
>>30331479
>Just hope subsonic gets the job done.
seems to work just fine since 1911.
Rail assisted coil gun.
The projectile needs to have an electromagnet core powered by a two part conductive barrel/rail.
Magnets are shit bullet material but magnetic force on magnetic force will double the coilguns power.
So far we have only seen one half of the equation. Metal propelled with magnetic force so all prototypes are only half built.

and then i'll mock them as Muhammed Jefferson the 34th rapes them because they had to plug their gun into the wall.
>>30331362
>No recoil
I'll get to this below. You kinda have a point, the others are rubbish
>No inaccuracy
Any projectile is susceptible to inaccuracy
>No noise
Again, wrong. Once you have supersonic projectiles, you'll start having sonic booms. Additionally, any Gauss Gun will have to have moving parts, and these create noise.
So, the problems with Gauss Guns and why Rail guns are a better alternative: The Post(s)
First off, let's define what a Gauss Gun is:
Gauss Gun and Coil gun are synonymous for a device that accelerates a ferromagnetic projectile through the use of electromagnets. Basically, you have a chunk of steel, or iron with a coating, or some other ferromagnetic alloy (i.e. containing a large fraction of either iron, nickel, or cobalt) which, as you know, is attracted to magnets. So, you have a coil of wire, usually several, around a barrel, and they are switched on to attract the projectile. Because the projectile is only attracted to coils, not repelled, once the projectile is in the middle of the coil, it is switched off, so it does not decelerate the projectile. Then, the next coil is switched on, and the process repeats, until the projectile has left the barrel. Basically, a Coil Gun is a magnetic slingshot.

Cooling, energy source.
>>30331663
>Recoil is function of the mass, and square of the velocity of the projectile
If it was velocity square then there'd be no recoil, since kinetic energy is non-directional.
It's momentum you're after, so just mass times velocity straight up.
>No recoil
>What the fuck is the Third Law of Motion
>>30331870
This causes an almost constant acceleration, which is where the myth of "no recoil" comes from, I think. In a firearm, you have a sudden spike of acceleration as the gunpowder is ignited, which drops off sharply as the gasses expand into the barrel, pushing the bullet ahead. Good old Newton tells us that the greater the acceleration, the greater the force. Think of the difference in recoil between a forearm and a Coil Gun like the difference between someone hitting you with a hammer, where the hammer only touches you for a brief period of time, and someone pushing the hammer into you over a longer period of time. The average force is the same, and so is the acceleration, but the force for a firearm is a sharp spike that, at its peak, exerts more force on your shoulder when firing.
>>30331448
>>30331479
>>30331523
So, a coilgun exerts far less force on your shoulder, and therefore the recoil is (presumably) easier to manage. See pic related for my MS paint illustration
2/?
I don't know about the specifics of magnetic field guns but if there is no gases leaving the barrel with the bullet, there would certainly be less recoil.
>>30331479
Your last argument is somewhat flawed. There are a number of air guns out there...
>inb4 air gun memes
... that have the same ballistics as some high powered pistol caliber carbines and are completely unregulated because they aren't firearms. They can even have integral suppressors and don't require an NFA tax stamp.
The rest of what you said is correct.
>>30331932
Now, what are some of the problems with Coil Guns? Well, for a start, they run off of electricity, so you always have to have a charged battery to fire them. Additionally, they need to run on the same current, otherwise every shot will travel at a different speed and will therefore have a different trajectory. You can get around this problem by charging capacitors that have a high current output, but these are currently bulky (see https://www.youtube.com/watch?v=7LjnhhtHojM ) and take a few seconds to recharge, and therefore you can't rapidly fire.
Another problem is that, because you're sending a lot of current through these electromagnets, they'll heat up. However, because they are likely strapped close to the barrel (The closer, the higher the magnetic field strength, the higher the efficiency of the device), it can be quite difficult to cool them.
Additionally, you're creating a large magnetic field around yourself and the device, so any electronic devices nearby may be damaged, unless you have some sort of way to divert the field, which is usually in the form of steel plates that redirect / reshape the magnetic field. Steel plating is, of course, heavy.

Is anyone interested? If not, I'll stop posting
>>30332089
This is pretty cool desu senpai
>>30331362
Until they upgrade the ATF to include energy weapons like in Fallout 4.
Some madman did it?

Tbh, you'd have a better time learning to throw knives than have a coil gun. And, with knives they can be used in many situations. Seriously, asking for people to engineer a coilgun is like asking someone to make a not-so-child safe nerf gun that fires metal bits.

>Why aren't you engineering coilguns guys
Because at the muzzle energies that hobbyist coil guns produce, you might as well just put an air compressor on a hose with a hopper on it and make a BB machine gun.
No doubt they're cool, but they're toys until we can get better power sources.
>>30334665
Feels pretty fake.
>>30331362
Cool design.
Needs to be waterproof and completely self contained (besides battery and flechettes) to prevent gunk.
No rifling = no spin / stability means it can't shoot any significant distance (yet)
Redesign the dart with fins like any modern flechette weapon and it could have some great potential when velocity is up to par with combustion weapons.

>no moving parts besides ammunition

This isn't /b/ how the fuck did you get out of containment?
>>30331362
Why coilguns?
Railguns can get far higher outputs and are alot simpler.

The hot rail designs will corrode the rails. Guass cannons are better in this reguard as you will have a longer service life.
