How do I train the 360-degree turn required in ranch riding patterns?

The 360-degree turn in a ranch riding pattern is a full circle in place — the horse rotating around its hindquarters in a complete revolution before continuing with the next element of the pattern. It is not the high-speed spin of reining competition; it is a controlled, correct turn on the haunches executed at a pace appropriate for a working horse demonstrating its training. Judges evaluate the turn on the correctness of the footfall — the hindquarters remaining relatively stationary while the front end crosses around them — the willingness of the horse, and the evenness of the pace throughout the revolution. The foundational work for the 360-degree turn is the turn on the haunches, built progressively from the horse's ability to move its front end around a relatively stationary hind end in response to a direct rein combined with a supporting outside leg. This foundation is established at a walk, with the horse making a deliberate, correct quarter turn and then half turn before the full circle is introduced. The correctness of the footfall is established at slow speed before any pace is added. The primary fault that judges note is the horse's inside hind foot walking a circle rather than remaining as a pivot point. This fault reflects either insufficient foundational training or excess speed that causes the horse to lose the pivot as it tries to carry its own momentum. Returning to slow, deliberate work and reconfirming the pivoting hind foot corrects the fault more reliably than attempting to hold the foot in place through rein pressure during the turn. The turn should begin and end cleanly — no preparatory steps that add extra movement before the revolution begins, and a clean departure into the next maneuver when the full circle is complete.
