Everyone who does home reloading would love the RCBS Neck Expander Die-Complete Die. For sizing the neck of a case, this expander is an excellent choice. The die is affordably priced, made from high-quality steel, and comes with a lifetime guarantee from the company. In addition, this die comes with a neck sizer with expander/decapping unit that is made to flare the inside dimension of the case neck to just a little more than the actual bullet diameter. With this, alignment during the seating process is perfect. Included with the die is a convenient plastic storage case.
