cannon barrel ratio

[FlyingTaters07]

do air cannons have a good cannon : barrel ratio? if not is their any rule of thumb to how big the chamber and barrel should be?
Thanks, Mark

that did not make sense at all
to get the most bang for you buck, use the gun optimizer in the GGDT
works like a charm. it will tell you what your chamber or barrel should be for maxium power

sorry, i have no clue at all when it comes to pneumatics. I was going to try to make one from scratch and i was trying to figure out how long the air chamber should be compared to the barrel.

Like saladtossser said, download the GGDT, and use the gun optimizer to get your ratio.
