Considerations & Trade-offs
- Designed specifically for .38 Special and .357 Magnum, so it is not a general-purpose die for other calibers.
- Its function is limited to charging the case while expanding the case mouth; it does not replace other reloading steps or tools.
- It is intended for use with a powder funnel adapter or Lee Auto Disk, Pro Auto Disk, or Auto-Drum Powder Measure, so compatibility depends on the rest of the setup.
