      I was thinking about those, but I understand they tend to suffer from inaccuracy due to even slight imperfections in the manufacturing of the jet openings.

      I think something more like a conventional round, with a heavier casing and more propellant might work. The casing gets ejected backwards and the projectile forwards, without imparting momentum to the barrel. You do need more propellant to get the same muzzle velocity though.
