The old double tap works fine if presented with a single target. DT'ing when there are two or more targets may just allow the other to get you. I read somewhere recently of a tactic for more than one attacker. Shoot one once (which one is your call based on proximity, threat etc) then double tap second target, return to first target for finishing shot if needed. They didn't say anything about more than two targets. My guess would be single shot each (there is that peskly first shot importance again) then return to targets as necassary to neutralize. Any thoughts?
