if you know when to use it. Swat teams use it when they think the person is using body armor. If they don't get a reaction from double taps to the 10 ring. They go for "pockets" to stop the individual. It is not the first target, but I would go for pockets before a head shot anyday
All this talk about where to put the bullet is driving me crazy. It is this simple
You shoot center mass until you get a reaction. Some people say shoot at the target 1.2 times in the upper left shoulder between the anus and skull. Thats bs! Sometimes you can't even tell you are hitting the target more or less pinpoint a shot. Don't count your rounds! Program your mind to shoot until you get a reaction. You shoot someone twice and pause...."umm ok did i hit you? no you didnt ok let me shoot you again" haha it does't work that way
sorry!
