I once shot in a counter-terrorist rifle compertition/assesment where the targets are large photographs of terrorists with hostages, the ranges were variable and unknown between 60m and 250m and some of the targets were partially obscured. You had one minute or two minutes to engage as many of the targets as you liked, they were scored differently depending on how challenging the shot was but the big factor was that if you took a shot and missed or hit the hostage (obviously!) you incurred massive penalties. It really teaches you to shoot with confidence but only within your own (or environmental) limitations. The scoring system was very well worked out so that competitors had to take on the shots to win, you couldn't just play safe. I only scored averagely as I played too safe looking back. Glyn
