I found rumble was my best friend for this quest. Usually what I would do was use a hand cannon (I was using ace of spades) to get a feel for the other players then I'd switch to TLW if I was doing well. It also helped that I ran into a match where 3 people where trying to kill me with sword hilts. (Although I later lost all that percentage by playing while drinking). It's aggravating but doable.
