How about a 10 megajoule railgun?

Actually it is impressive because high velocity projectiles and launchers are much more difficult to pull off than very massive conventional chemical propelled projectiles.
E=(m*v^2)/2. Whereby energy is equal to one half the product of mass multiplied by velocity squared. The addition of one unit of mass only contributes half that value to energy gain. The addition of one unit of velocity contributes the square to energy gain.
Its fairly easy to understand why additional velocity has much more value than additional mass. Material also acts funny under hypervelocity impacts and high velocity impacts appear to have much more destructive power than an equivalent traditional "standard" velocity impact.

Is that funny "Ha ha" or funny "Thats not normal"?
I remember one of them in the '80s that fired an 11 oz Lexan projectile with a muzzle velocity of 14,000 mph.
(that's 4,812.5 gr at 20533.33 fps)
Of course, the rails had to be replaced every other shot, and the SWITCH to activate it had to be replaced every shot.
I wonder what happened to the compulsator-powered 9 MJ coil gun the Army was testing back in the '90s? We never heard anything about the results... (Yeah, the Army was looking at slinging them on tanks... the size shells they were looking at, 'point blank' range would be out to the horizon!)

One unit of velocity adds half the square of energy gain, you silly goose.

Saw this story here:
http://www.livescience.com/technology/080201-electromagnetic-record.html
and a video here:
http://www.livescience.com/php/video/player.php?video_id=080201-railgun
Some of the still shots match the Fox story, but the Livescience video shows what is clearly a conventional chemical propellant gun with an extended barrel firing a high velocity sub-caliber sabot round from what looks to be an 8 inch gun. Cool video and really impressive muzzle flash, but nothing electromagnetic about it. You would think that someone at place called Livescience would have a clue about reporting a technical story, but apparently not. Another -1 for mass media reporting.
No high tech clean room stuff in this video. Looks more like some guys in a glorified garage that happens to have an 8 inch naval gun and suitable range out back. Looks like fun to me! Also like the background sound of a couple of bursts from a Ma Duce as the video pans along the gun barrel.
I tried the video link from Fox but it did not work for me. Maybe that has something to do with the fact that the link is to a .mil site and I am currently in the Middle East. No need to give some folks in this neighborhood ideas about big guns with a range of 200+ miles. They might try to sneak one into a shopping mall in Hoboken and panic the sheeple.

In Dale Brown's books starting with Tin Man, the BERP suit wearers use shoulder fired railguns. Can take out aircraft with em.
The government needs to contact Sky Masters.
