: 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?

Sorry, you misunderstood me. Let's say I have my gun chronoed at 280 with nitro, i then unscrew it and attach CO2 and my gun shoots 210. Is this noraml? It seems to be to me, but a ref told me they should shoot the same.

Thanks in advance.
