Seems silly to risk blowing out O-rings. What output is the tank? If you can get it to 550, you are fine, but pumping 800 psi into it just to test it before you play seems like a bad choice.
This is how I feel. Its really to make sure you arent blowing frame orings, which is a legit concern. Normal LP should suffice tho. If the regs are doing their jobs, they should be able to handle the pressure. I feel like Bob would keep that in mind. People are going to put HPA tanks on the markers. If you send them out with regs that will self destruct under standard HPA pressure, youre gonna have a bad time.
