The Lee Precision Collet Neck Sizer Die for .243 Winchester resizes only the case neck using a collet that squeezes the case against a precision mandrel. This approach promotes consistent bullet alignment and reduces runout while eliminating the need for lubrication. The die is offered as a single-unit (die only) option for reloaders focused on neck sizing and accuracy work.
