You'd need to reclaim a lot of energy very quickly because after the projectile's exit the atmospheric pressure is going to slow you down right quick

You could slam a blast door closed behind the exiting projectile. It should be possible to place it in the exit tunnel so that it is fully closed before the inrushing atmosphere gets to it.

Plausible. Do you know how fast such doors can close?
