Might come in a future update, but that would be after the rating period has ended. We'll see. I do agree that I gave people too little ammo. Didn't have time to balance stuff.

If it's the very first jump, you need to time the shot about at the same time as you jump. Sounds counter-intuitive, I know, it's a weird physics thing. If you're talking about the second one, spoiler ahead, you're supposed to fall into the ditch and find a pistol you can combine with the shotgun to fire faster.
