I normally don't condone boosting, but if you really want this achievement, it's pretty much the only way. Even when boosting with friends this is tough. Basically, you need to have 4 people stand in a tight circle right on top of each other. Throw one stick to damage them, then a second stick to kill them. All 4 have to die with the second stick.

Kill 3 people without dying with one shot from the sawn-off shotgun. They can't be damaged, and you have to kill them in a single shot, so get close and aim for the head. This achievement is also very buggy, so it probably won't unlock the first time you do it.
