My methodology is a bit different, but I do get those nice surprises often. I rarely saddle up or stick with one enemy for a long duration fight. My convergence in the jugs are set to either 225 or 250. I rely on deflection shooting within that range, which 90% of the time equates to a kill, or at least catastrophic damage. After I take the shot, I keep on trucking to the next opportunity.
