Lee Powder Through Expanding Die .38 Special

The Lee Powder Through Expanding Die for .38 Special (model 90581) combines case mouth expansion with powder charging in a single efficient step. This specialized reloading die is engineered to expand the case mouth while depositing a precise powder charge, streamlining the reloading process for shooters who prioritize speed and consistency without sacrificing accuracy.

The powder through expanding die works in conjunction with Lee's powder measure system—either a manual powder funnel adapter or the Auto Disk and Pro Auto Disk powder measures. This integration allows the operator to charge cases and expand the case mouth simultaneously, reducing the number of separate die operations required. The .38 Special caliber is one of the most widely reloaded handgun cartridges, valued for its moderate recoil and consistent ballistics across a wide range of powder and bullet combinations. By consolidating expansion and powder charging, this die reduces handling and setup time while maintaining the precise dimensional control essential for reliable ammunition.

This die is designed for serious handloaders working with .38 Special—whether for target shooting, practice, or defensive ammunition development. Reloaders who process high volumes of .38 Special cases benefit most from the efficiency gains of a powder through die setup, as the combined operation reduces die stations required on a progressive press or speeds up single-stage and turret press workflows. Lee Precision's powder through expanding dies are industry-standard components for handloaders seeking practical efficiency without compromise on case integrity or powder charge accuracy.
