I dunno. Hairspray is a pretty sucky propellant. I wouldn't think It''d get anywhere above 30 PSI. 16 PSI actually sounded pretty reasonable because I think this guy's measurements are all about 10 PSI short. So about 26 PSI average.

Switch to starter fluid if you don't want to go with propane.

Butane would also give your gun a better shot. But with the little nozzles on the refilers are a pain in the a$$ so it would take some time to get the mix right.
