I got a couple of 1/4" ball valves that would make a good trigger style pilot, might make a "12 bore" high pressure co-ax...

Update--Tested it a long time ago, just haven't posted anything.

Have decided to abandon this project due to a disappointing lack of power, going to consider a hybrid cartridge with a friction fit tubing like JSR was considering with his burst disc-less type.
