Checking a C02 Build, looking for input

[gungecko]

Hey guys new member, but not entirely new to pneumatic cannon builds.

I am looking to assemble a C02 powered cannon utilizing a QEV and 3 way valve to fill a reservoir from a larger source to allow for proper expansion and consistency in shots. i've attached an image that roughly lays out the plan. previously i was charging an expansion with the 12g co2 carts but thats a little costly.

my concern is that the QEV will not handle C02 well, my other concern is i am over engineering this and i don't need to have so many parts to consistently dump 12g cart volumes through a valve.

the main must be included part is an electric solenoid of some kind that is 12dc this is triggered with a reed switch.

I should say try using a pcp tank

or a paintball tank if it can only work with air
