The Hornady PTX Universal Powder Drop Expander for 45 caliber (0.451-0.452″) is a powder-through expander intended for reloading applications. It is designed for use with Hornady Quick Change Powder Die systems as well as case-activated powder drops. The expander is inserted into the powder die so the powder drop sits on its surface, producing an expanded case mouth to the desired diameter without requiring separation of the case mouth on a separate expander die.
