I was wrong about one thing, a bullet does have more kinetic energy than a sword. I knew momentum would be much less, but I would imagine kinetic energy is more important. Using these numbers I found:
M16 Bullet:
0.0039 kg, 853 m/s (muzzle velocity, I would assume if we are talking sword vs gun the range wouldn't be more than 50m)
kinetic energy = 1419 J
momentum = 3.33 kg*m/s
Two Handed Medieval Sword
1.6 kg, 27 m/s (source on speed is a bit sketchy, but from what I can tell it should be close)
kinetic energy = 583 J
momentum = 43.2 kg*m/s
a sword would have to be swung at 42 m/s to have the same kinetic energy
