if you have the DLC just load chapter 9 act HORNETS NEST, kill first wave of enemy and then jump down into next section and kill all enemy that keep on spawning you should get about a 100 kills in a few mins of playing. Rinse and repeat.
Just a little update for this kill grinding solution once you have killed the 1st wave on enemies on the upper level, once you jump down the ladder to go into the warehouse section hold your AI partner so he doesnt steal any of your kills. After killing the 2 easy shotgun heavies, what i done was to take cover behind the forklift truck and you can see them keep spawning through the big shutter door infront of the forklift truck.
