OK you techno-guru’s
Just what the hell is this thing ? ? ?

Would like to see its penetration from a decent distance rather than right up against it. 10mm of steel plate is impressive, but doesn’t translate very well when that close.
🙂 Yes, but power:size, it is much out done by the Hybrid or ETG.
Heck, the hybrid produces a 5300 FPE with a 250 grain bullet, It would be much larger for a lead full bore projectile.
After the barrel damage, he added a golf ball barrel and shot golf balls through car doors like it was punching through paper

Railgun/Coilgun for the win!!
In theory, limitless FPS as long as you got enough barrel/electricity
That is no way aluminium, it clearly is hard for him to manouver and falls on the floor with a good thud.
The Barrel also bends like hell when the plate falls down on it, and he is using a thick walled tube, thicker than 1/4″ I know.
Here is the steel plate
The projectiles
933.3 Metres per second / 3062 fps with a 16.6 gram projectile.
A projectile stuck in the barrel and caused this bulge, second picture is showing wall thickness
Here are some of the drawings and parts

steel my ass, he moves that plate with such ease that its gotta be something else….my guess is aluminum….impressive however !
It really is surprising isn’t it 🙂
Dave
Holycow, that shit is powerful.
If you really want something fun, look up an ETG, or electrothermal gun.
High voltage is passed through aluminium powder which then vaproises into plasma which super heats the air and the expanding air fires the projectile.
A chamber the size of a smarties tube will yield over 9000 fps (Not a typo) at around 10% efficiency.
Here is a video and the original thread on a spudgun forum that I am a member of.

Or for something else, try a hybrid spudgun, using just HPA and regular propane, this gun has a muzzle energy greater than a .50 BMG
Here is it piercing 10mm steel plate like butter.
Everyone has seen a potato cannon, well basically, a mix of 4% of propane and 1 atmosphere of air (Regular atmospheric pressure) will combust. Add 5 times the mount of propane, and add 4 more atmospheres of air and you have a combustable mix.
Contain this mix with a burst disk that will burst when the mix is ignited and it is that simple.
Not bad for a 17 year old gun restricted Brit 😀
i can see the fun of constructing a thing like that….but judging from the video the power is still very low. i mean the projectile does pierce the microwave oven, but the spike doesnt make it though only the tip
the military one seen on tv is a part of a railgun project that aims to fire a projectile beyond the horizon, at speeds where where it cannot be stopped or shot down…and with power enough that it combust upon impact creating an explosion, much like a meteor would.
another one also seen on tv shoots a hunk of metal so fast that the metal literally melts off the projectile in flight due to air friction (like the space shuttle entering the earths atmosphere)
the govanator made a movie where such portable guns where used…fictional of course
its an interesting concept, no explosive materials, casings and such, just the projectile and a power source…..soldiers would in theory be able to carry much more ammo, but so far they have been big and bulky….capacitors and battery’s weigh a ton….so until thats been figured out i think it will be limited to ships and maybe tanks
there was a project of a space cannon, that could launch satellites into orbit, using massive amount of explosives, and a long barrel…..but most satellites disintegrated upon firring, or never made it up far enough…..maybe the rail gun concept could be used here as you could program a steady acceleration, vs the explosions rather sudden acceleration….hmmm
Isnt that the fucking point. Its not hunting its war.
The reason that the millitary is working on it is, they say that no conceiveable amount of mobile armor could withstand a direct hit.[/quote]
I think that the concept goes back to WWII. I believe that the germans were working on it. Their idea was to rain more bad news on England. They couldn’t figure out how to make it work.
These days we have computers that can sequence the magnetic pulses fast enough to make the concept work.
There are several amusement park rides that use this technology. I think of “California Screamin'” at Disneyland’s California Adventure Park, and “Superman; The Escape” at Magic Mountain here in So. Cal.. I have been on the Disney roller coaster and it’s 0-80 in in what seems like 1/2 second…probably more like 2 seconds.
Speaking of the For Sale Section; I have my just delivered, never even shot, Greg Davis tuned Marauder for sale. It comes with all of the goodies, cost me $840 and is going, right now, for $765, shipping included!
HURRY ON OVER THERE WHILE SUPPLIES LAST! Operators are standing by! 😆
The tank cannon that the millitary was testing had a truly awesome muzzle blast! It looked to be 3-4 times that of a M1A1 120 mm smothbore!
That coil gun had 2 major drawbacks. 1) It needed a generator that looked to be about half the size of an Abrams. 2) the violence of the firing, muzzle blast and energy dump would erode the barrel so rapidly that it was only good for a couple of shots.
The reason that the millitary is working on it is, they say that no conceiveable amount of mobile armor could withstand a direct hit.
Yea no shit good explanation. Next thing you know OG will be offering the up in the For Sale section. 😯 😆
Wow oldgoat… Good explanation. I’ve never heard of one, but sounds like I don’t want to be on the receiving end of one….

I just did the FPE calculation based on some numbers from the wikipedia railgun article. On January 31st, 2008, the Naval Surface Warfare Center fired a test projectile with 7497377.15 FPE. 😯 HOLY SHIT.
