The Hornady PTX Universal Powder Drop Expander for 9mm (.355/.365-inch, part no. 290030) threads directly into a Case Activated Powder Drop on a Lock-N-Load AP progressive press. Instead of running a separate expander die to flare the case mouth, the powder drop itself expands the case at .355/.365 inch as it meters powder, which frees up a press station for a taper crimp die or a powder cop instead. It works with both lead and jacketed bullets at this diameter, making it a flexible choice for reloaders loading 9mm on a Hornady progressive setup.
