Article: "How To Deliver Accurate Hits On The Move"

The article is from Shooting Sports USA, and the key point seems to be this:

      The key to shooting accurately on the move is to lower your center of gravity, smooth out your stride, and lock the gun arms onto the target for recoil control. However, the most effective stance can vary among shooters due to body type. The degree of crouch and knee flex will be different for a tall, slender shooter than for a shorter, stouter shooter.

      Find yours by setting up three targets, spaced 6 feet apart. Face the middle target at 10 yards. At the buzzer, draw and double tap each target as you move forward. At 5 yards, repeat as you move backwards. At 10 yards, start on the outside of a far target, and double tap each as you move laterally across the targets. Do this left to right and right to left. The time is not quite as important as the target score. This is one case where accuracy takes a slight precedence over speed.

      The “Crouch and Slide” covers ground more slowly than a walk, jog, or sprint. But it’s only needed when you’re actually pulling the trigger. Savvy USPSA shooters have learned how to enter and leave the stance quickly as they move through a course-of-fire. Practice this by starting at 15 yards, sprinting to 10, and then assuming the stance and engaging the targets while moving forward.
