The Lee 90580 Powder Through Expanding Pistol Die is a workhorse tool for 9mm Luger reloaders who want to streamline their handgun ammo production. This two-in-one die handles case expansion and powder charging in a single station, letting you move rounds through your press faster without sacrificing consistency. It's built for shooters who are serious about efficiency—whether you're prepping rounds for competition, practice, or personal defense.
Powder-through expanding dies let you charge cases while simultaneously opening the case mouth to diameter, eliminating a separate step at your bench. This die works with powder funnel adapters or pairs seamlessly with Lee's Auto Disk or Pro Auto Disk Powder Measure systems, giving you flexibility in how you set up your reloading sequence. The design cuts down on handling and keeps your workflow smooth, especially valuable when you're processing volume.
Lee Precision dies are known for solid, no-nonsense engineering. This one is no exception—straightforward geometry, reliable performance, and a price point that makes serious reloading accessible. If you're building 9mm loads and want to cut bench time without corners cut, this die earns its place in your setup.
