A homebuilt, portable railgun is claimed to have achieved projectile energies comparable to commonly available air rifles.
In the picture above, the capacitors, which store the railgun electrical energy, have been painted white. They are the large cylindrical objects at the front and bottom of the gun..
Here is a video of a test of the railgun. The rail gun can be carried, contains its own power supply for a single shot, and expels a projectile fast enough to make a half inch dent in plywood. It probably would have penetrated the plywood, if the plywood had not had a steel backing.
The original post only says that the velocity was over 250 meters per second. That translates to 820 fps, or 560 miles per hour. A poster on freerepublic noted a critical, and missing bit of information. From freerepublic.com:
“How heavy was the projectile? An arrow traveling at 800 fps is a formidable projectile, for instance. Mass matters.”
I was able to find the mass of the projectile with some Internet research.

My airgun shoots .22 pellets at 1200fps. and the pellets are readily available. Five hundred rounds for $9 at WalMart.
Go to a car audio store, get a bank of Subwoofer caps and blow holes in schools.

I got me a Ruger squirrel break-pump rifle, I just wish there was an air rifle I could load up with multiple rounds even if I had to pump for each shot, it is annoying trying to load little pellets one by one with gloves on in winter when i am plinking squirrels and small game.
There are some out there:

what does ‘fps’ mean in this context?
sorry, but as a software guy, all i see is ‘frames per second’
what does ‘fps’ mean in this context?
Feet per second. 820 feet per second.
Air rifles attain those velocities with about the same weight projectiles.
Career 707 is a Korean (another reasopn to buy it) vs. it being some chinese crap.
I have a Daisy pistol where I can shoot five pellets fast as I can pull the trigger. It’s CO2 fed but those pellets can bust glass bottles at ten feet or so. Crawling in the basement for mice or rats it comes in handy.
Yes, and you don’t need to charge it for an hour or two before you use it!
wile interesting, it seems like a silly endeavor when one can buy a really good air gun (1200fps/.177) for under $200 and have nearly unlimited shooting.
What is the make/model of yur air gun? I think I want one of those.
A tiny tungsten pellet, small bit of water, high energy electrical discharge to push the round and overcome the initial inertia. From there, use laser to time the discharge of the coils.
What level does it spawn on?
I had a Crossman semi-auto 22 cal C02 pistol once upon a time. It had a tubular magazine on the barrel and a widget that transferred the pellets to the chamber for firing as fast as you could pull the trigger. It had enough power to take down a grown cotton tail rabbit.
Here's the pro version:

It accelerates a projectile to Mach 6, about 6700 feet per second.
Do you know how they guide the projectile?
