Build Your Own Gauss Pistol

BdosError writes "A Russion software developer has developed a homemade Gauss pistol. It's not very powerful yet, but as a proof of concept, it's interesting. Nice, non-chemical slugthrower that should appeal to fans of Science Fiction and related games, like Traveller and many others."

They don't exist?

Using a series of magnets to accelerate a metal slug - it doesn't seem like it would be that hard to do. Right?

Also, aren't "Guass Guns" are more widely known via the games (both board- and PC-) BattleTech and Mechwarrior?

Gauss Rifles are from battletech.

Interestingly, I don't think the mass of the slug makes all that much difference to the eventual damage - force = mass * acceleration

So using lighter weights would be advantageous, up until the point where the projectile becomes too light to keep a decent trajectory in a cross wind.

And of course, there is the Particle Projection Cannon, with a charged particle instead of a magnetic slug...

Evgenij Vasiljev does not claim this is a new concept. What he claims (and I do not know enough to validate this from his data) is that his prototype is the most efficient (by which I think he means velocity relative to power input) yet developed. It is dangerous to judge a book by its cover but, based on his site, it looks like a very interesting project.

This does not quite translate into how a round will effect a target. Particularly a soft one. A light projectile travelling extremely fast will penetrate a human (for example, lets take the NATO 5.56x45mm round) and do significant damage, but won't always be lethal, because the high velocity causes it to penetrate and keep going, rather than transfer all its energy to the target. Compare to a 7.62mm round, which is traveling slower, heavier than a 5.56, but it does LOTs more damage

I'm wondering how the existing laws of various countries hold up against this weapon. Don't a lot of laws specify the weapon by the method the projectile is accelerated (i.e. in existing cases a chemical reaction)?

Does this weapon circumvent any laws against firearms?

While the parent post is disturbing, I will respond regarding this post. Sub-sonic ammo with silencers take care of most of that problem with traditional guns, while coil guns are tunable with the desired weight and size of the projectile used in them to keep the round sub-sonic

Of course it is possible to keep the bullet subsonic, but then your weapon is pretty useless as a sniper rifle.

There are very active research programs going on in a number of defense groups concerning rail guns at all scales from personal defense to large scale cannons.

Yes, and of these I think the cannon are promising but the personal not. For example, by putting the this into artillery on an aircraft carrier you can shoot further and more accurately and you get power from the nuclear plant.

But for a personal weapon, you have just exchanged a small case of gunpowder for a big battery, and you have gained...what? Not range and accuracy; these are limited by the markmanship of the user and not by the speed of the bullet.

You know what else is small, silent, and powerful enough to kill a man? A rock.
And I can fit a whole shitload of rocks in my pocket.

Watchout! I'm an arms dealer!
