Ballistic Knife + Sickle. If you knife him in long series for 10-15 mins, he will die. Combine this with a friend Floppering, he dies faster.
Usually the guy with the ballistic should get the wunderwaffe, while the other guy has the upgraded AK74u, upgraded HK with the dead shot perk. Should get you round 45+
