QB79 1250 psi, the AirMan?

Hi.

Anybody used one of Johns "1250 PSI 13Cu In" bottles on a QB97? I'm concerned that 1250 psi may be a bit high for safety. Would this pressure be sufficient to drive a 0.177 8.8 grain pellet at 800 or so FPS?

Do Johns regs have blow out disks on the low pressure output side?

Regards Ora

I think Mike uses a trick valve spring..(taper wound?) that helps output - classicalgas on Jul 12, 2008, 11:09 AM
