PCP on other then air or co2?

You can use Nitrogen (a good choice), or Argon (although the performance will be less than air).... or Helium.... On NO condition use Oxygen, any small remnant of any lubricant inside the gun can explode violently....

I was thinking of Nitrogen or helium, I can get them in tanks with a 6000 psi limit. The PCPs I have been looking at are 3000 PSI max so I will have to step it down. If I can't find a way then I'll just get a scuba Tank and use air for now... thanks.
