I have heard the same thing from instructor Gil Ash about engineers. They can be difficult students. The problem with engineers is that they are trained to measure precisely, and shotgun shooting is not precise. If shotgunning required precision, believe me, I couldn’t do it. Engineers, or so the stereotype goes, want to measure and double-check everything, including the distance between the bead and a target as they lead it. As soon as you start to measure with a shotgun, you look at the bead, and your swing slows or stops dead.
