barrel to chamber size ratio on pneumatics

[Jimpson]

Does anyone know a good C:B size ratio for pneumatics? I have a copper gun with a 3ft barrel, and about 2.5ft of 3/4 chamber. THe barrel is 1/2. I want more power!


Thanks

I don't think there is an exact known C:B ratio, but if I was to guess i'd say something like 2:1 or 3:1

There is no best chamber:barrel ratio, going either way, for a pnematic. Why?
Because if you have no limmets on chamber size, you want it as big as you can afford.
...Or, if you can't change your chamber size, the optimum length barrel will vary depending apon your operating pressure. I suggest downloading the GGDT.

depends on your operating pressure
