coxial shells for gb cannon

[carter]

i was thinking about making a new golf balls cannon but i have having to pump up the bloody thing all the time. i was think of making cartridges when i'm on the move to make things quicker. anyway i thought about using a coxail piston valve. but so its more compact using a burst disks triggered by a sharp blow like a spring loaded nail to exhaust the piston?

tell me what u think
