Pyroninja its going to shoot golf balls, the only thing i dont like about it at this point is the length of it, The barrel is 5 feet plus the stock and bolt. Any ideas about making it shorter?

Instead of the stock, you can just use the bend between the chamber and barrel.
What will the ignition be?

So the fuel injection will be via a solenoid?
Sweet.
You should get a four-way manual valve and a double acting cylinder and use the propane pressure to make an autoloader as well. 8) Just run the exhaust, (if it's a four-porter), back to your meter.

It was just a joke, really. I was saying to make a pneumatic auto-loader with the propane pressure to move it, basically.
