But you're wasting some energy from the band into the blow back mechanism. It's interesting you all are taking the same approach of actuating the mechanism right after firing the band. My original intention was to actuate the mechanism only after having fired the bullet so as not to waste energy and to slow down the fire rate to something reasonable. But best of luck, hopefully this concept turns out.
