I begin by crashing the antlers together. Then I twist and work the antlers together in an effort to imitate the sounds of two bucks sparring. My entire rattling sequence only lasts about 15 seconds. I try not to rattle more than once every 10 to 15 minutes because the last thing I want is a buck to catch me rattling. It’s happened more than once and every time the results have been less than desirable.
