If it's made like a normal multibarrel cannon only one barrel fires at a time and the rest of the rotation is used to reload each barrel.

Could be running at 1200psi. Just have to use a smaller volume of gas for each shot than if it was using a lower pressure.

If it is CO2 then 1200psi might be a tad optimistic.

quote, "It starts out fine but near the end you can hear only 3 out of the 6 barrels firing. The catches on the other three wore down and wouldn't release." endquote

He hadn't hardened the catches on the barrels so they wore down. That's why we only heard some of the barrels going off.

Ive seen this in a (aus) PCPowerPlay mag. In the geek gadgets. They cost $15000 US.

They work. But for 15,000. Crazy.
