just wanted to confirm how i could increase the muzzle velocity of my pneumatic rifle ????

Should i try increasing the chamber volume or should i try increasing the chamber pressure???
(Currently running 30 cubic inches at 150 psi)

Help Needed......thnx!!!!

What is most efficient depends on the barrel. How long barrel u have and what is the diameter at the barrel?

Both will do it, but I'd suggest increasing pressure since that's usually easier, but not if you'd be pushing the pressure rating on components.

Increasing chamber volume is effective up to a point, after that could can double the volume and only get a 1% increase in velocity. Increasing pressure on the other hand should give a roughly linear increase in power.

Download Gas Gun Design Tool and have a play before cutting.

Then increased chambervolume wont make any noticable difference :)
