Dr Malcolm Plant, chairman of the Institute of Clay Shooting Instructors, gives a masterclass in target practice
Down-the-line trap (DTL) shooting will refine all the four building blocks mentioned, but this clay discipline is particularly useful for honing the first two: stance and gun mount. Quality DTL shooting needs to be disciplined and precise, with a considerable amount of mental focus. Unless you consistently get your feet in the right position, you will not be able to reliably cover the sky down-range with your gun, and out in front.
Furthermore, freedom of swift, but smooth, gun movement is critical and very dependent on your feet and upper body balance. An easy dry-run test is to set yourself up with an empty gun fully-mounted and cover the down-range sky with the gun; if any position of swing seems inhibited, adjust your feet.
