Since I had said use two so it shoots behind you, you'll get a recoil back from accelerating the bullet until it hits the curved part, then you'll get a force pulling away from you as it turns 180 to head backwards. At this point I don't know which would be more, you'd still have expanding gas during the turn so in theory it would still be accelerating.

Probably feel like a springer air rifle, back when you pull the trigger from the inertia of the piston then forward jump when the piston bottoms.
