You chrono with a velocity screw but if I understand your question, you are asking which gives you the more consistent velocities.

The answer is Nitrogen because it is a regulated air supply. Each shot is at the same pressure.

CO2 pressure varies depending on the internal temperature of the tank. Each shot you take evaporates some CO2 in the tank and it gets cooler. The next shot is at a slightly lower pressure so it will be slower at the chrono.

On the field you get into a fire fight and shoot 50- 100 rounds in 5 minutes and your CO2 pressure has dropped to half it was when you chronoed and your velocity is WAY Down.

Typical CO2 Example:
90 degress F & 1000 psi and 300 fps at the chrono.
Drops to:
40 degrees F & 450 psi and 200 fps during play.

You get bounces and shooting a mortar while the guy with the nitro bottle is hammering you with paint.

: Does CO2 chrono the same as HPA/Nitro?
