Lee Powder Through Lee 90620 Powder Thru Die 40 S&w

The Lee 90620 Powder Through Die for 40 S&W reloading streamlines your handgun ammunition production by combining two essential steps in one pass. This powder-through die expands the case mouth while simultaneously charging it with powder—a smart efficiency play if you're working up rounds on a progressive press or looking to reduce your turret station count on a single-stage setup. It's designed to work alongside a powder funnel adapter or with Lee's Auto Disk or Pro Auto Disk Powder Measure systems, giving you flexibility in how you feed powder into prepped cases.

If you're already running a Lee reloading system for 40 S&W, this die slots naturally into your workflow. The powder-through design eliminates the separate expanding step, which means fewer tool changes and faster cycle times when you're processing brass in volume. For handloaders who prioritize efficiency without sacrificing consistency, this is the kind of purpose-built component that makes your bench run smoother.

Lee dies are known for solid build quality and straightforward design—no frills, just reliable performance. The 90620 is a standard addition to many 40 S&W reloaders' toolkits, particularly those running Lee progressive equipment where every station matters. Whether you're breaking in a new reloading press or optimizing an existing setup, this die delivers the functionality you need to keep production moving.
