How about something like a PEST, but with a pneumatically driven rotor?
Or better yet, use an air tool to spin the rotor. Maybe a Harbor Freight die grinder or something.

70,000 rpm
With a one inch disk (lets say it goes down to 40,000 rpm) it could potentially shoot at well over the speed of sound.
The question is, can it sustain that actual rpm. Maybe with 1mm BBs
Realistically, a larger grinder is better for 0.177" or airsoft BBs
