DRY-Fire Drill: 90 Degree Transitions
Due to this drill using the corner of a room to simulate transition angles it is difficult to actually specify distances for the targets. If possible, I recommend simulating seven yard shots. Set this up so you get the full 90 degrees of swing between targets.
Work on wide transitions.
Start facing directly downrange with your hands relaxed at your sides. Engage each target with two rounds. Alternate which target you engage first.
