Something along the lines of artillery or planes or something else where reload time isn't a concern... sure.

They seem to show the pistol version a fair bit, but... how ya reload the thing seems a bit weird.

They do sell a secondary under barrel attachment 12ga thing.  Apparently to reload you swap out the entire barrel.  I dunno if this means the entire barrel has to be replaced after every firing or if there's a way to load them yourself like you would a magazine.  I suppose you'd have to clean the barrels for proper electrical contact as well.

If you've got a quad barrel 9mm pistol with 3 rounds each at say 5 inches... dunno how much useful barrel length you get, but carrying the pistol and then 1 or 2 extra barrel sets might not be too bad.  Again, depends if you can load the barrels yourself (gotta be able to practice with the weapon if you're gonna carry it.... having to order a pack of 100 factory barrels would suck).

There were a few history/discovery channel pieces on the company / technology.  One of them went into more detail concerning small arms (ie: pistol)  and that you'd swap out the barrels to 'reload' and that it would use a 9V battery etc.  It appears they're sticking with military stuff at the moment which makes sense - that's where the money is heh.

I'm kinda curious about their projectiles.  It's gotta be your ballistic tip (ie: jacketed lead fmj/hp stuff)... but ... in order to avoid bore obstructions, the brass case would need to be attached to the bullet as well (so that it pulls the brass out of the barrel so the next round isnt obstructed).  This would in effect make each bullet a mini missile / rocket.... projectile head + empty cylinder that held propellant.

How tight the gas seal between projectiles is also curious.  As such, are the bullets seated within the rifling grooves or are they sabot'd or something ?  Bullet running distance to rifling grooves would be weird in something where the rounds towards the front of the muzzle have less distance to the grooves vs those towards the 'breach' (as it were) would have a huge run measured in inches.

Anyone ever read any of John Ringo's books?  He wrote a whole series set in the near future where earth gets invaded by a swarm of carnivorous aliens.  One of the weapons devised by the humans to defend against the aliens is a Metal Storm system, made of multiple M1A1 barrels mounted on an M1A1 chassis.

In the book it was painful for the crew to fire.  I imagine so, but I'd shoot it once....

Back in the day….  In the 1970’s there was talk of a “Gy-rock” weapon that used rocket propelled rounds without the necessity for cased ammo.  Bullet and propellant both in a single package with the bullet having stabilizer fins to provide the rotation for a gyroscopically stable round.  I seem to remember one company (don’t ask, I can’t remember) that made prototypes and had plans for retail sale. 

All that to say that there is no real need for a brass case, only the propellant and a bullet, if the weapon is designed properly.

Just finished book 3.  Gotta stop by my buds place and return them to him and get the next in the series.  Great books so far, personally I’m kinda partial to the rail guns the Space Forces use.   40,000 shots before reloading! :D

There is apparently nothing really new under the sun anymore.....

Anybody remember seeing one of these pistols for sale when Western Gun was still in business in Lincoln?

This assumes that these weapons make use of metallic cartridges instead of http://en.wikipedia.org/wiki/Caseless_ammunition (http://en.wikipedia.org/wiki/Caseless_ammunition)

Caseless ammo... well yeah, it would have to be.

If it's the traditional caseless such as mentioned in the wikipedia article, I.... dunno.

Looking at the metal storm gallery for their 3 shot 40mm launcher.... the projectile portion of the round does seem to form the gas seal for the round in front of it.  The rest of the round doesn't particularly make too much sense to me upon first inspection.... I'll have to think about it some more.  Looking at the action shot of the projectile leaving the weapon, it's hard to tell if the black/grey part of the round is attached or simply gone.

This does bet some questions though.  If it is entirely caseless ... and going with their system of multiple rounds stacked inside a single barrel.... what happens if a round doesn't fire and then you try to fire the one behind it ?  Does the system have a way of detecting this bore obstruction ?

A picture of their 40mm ammo:

This shows the grey thing at the bottom is hollowish.

The black could be a hard caseless-ammo propellant, and the grey plastic either vaporizes or just isn't a problem, particularly in 40mm which isn't really high pressure afaik.
