Concentration is learned and earned through practice just like proper trigger control and grip pressure. You learn to tune out noises and talk by doing it .In the informal blackpowder matches I have shot if you can't take a ragging and still shoot you don't stand a chance,they will beat you without firing a shot. You learn to tune it out and stay with your shot routine,then you get to give a bit back. So learn to tune it out for the 5 to 10 seconds it takes to break the shot and you will be a better shooter for it. J.M.H.O.
