CO2 equilibrium pressure at 20C ~ 800psig
propane eq' @20C ~ 115psig
HFC134a eq' @20C ~ 70psig

800psig requires well engineered failsafed containers. Cast aluminum mags are pretty far off from safely storing CO2 compressed to liquid.

I have used CO2 regulated to 250psi for a custom shotty I built. I used engineered high pressure containment for the CO2 compressed to liquid and a pball regulator to consistently reduce pressure for the rest of the gun.
