I think i read somewhere that you can order spare (replacement) ejection charges from Aerotech - same pre-measured amount that comes with their motors.
Ask your local gun shops if they carry 4F blackpowder. Should cost about $12-$20.
This is probably a more appropriate discussion for the HPR forum so I've moved it.
you can get the vials from AT with Bp in them. You can also probably order them from mcmaster carr.
