So your external reg needs to regulate to the numbers above depending on bolt system, and the pressure supplied to your external reg needs to be higher. The numbers athomas gave are based on the integral valve regulator, so the input to your choice of external reg may be different based on its flow rate.

Even with these seemingly high numbers, the ball only sees around 80psi, I believe, by the time all the firing sequence actions take place.

Thanks for clearing that up. That's actually quite surprising. My Nitro Duck X-Stream should work just fine then (in theory). It's flow rate is high enough to not starve any of my RT's and it is externally adjustable.
