The best way used to be to go into classic rumble with a fireteam of 3 and just shoot each other in the face. This may have changed by now, but if not, that's your best bet.
But don't you need a 7 kill streak without reloading? Maybe I'm just not understanding the concept here, but doesn't that mean 7 kills in rapid succession and getting that triple tap bonus?
