4.75in FN Five-seveN was the test gun.
Pertaining to the original question: Even with an additional 600-700fps it still comes in well under 22cal cartridges generally accepted for hunting (.223rem, 22-250, 220swift, etc). Unless you are active duty special forces, the 5.7 is really just a novelty.
Since we're debating basic reading in reloading manuals; assuming the same bullets are used: How does 4-8grs of powder produce velocities (or muzzle energies) equal to 22-48grs of powder?
