The Lee Precision 380 Auto Quick Trim Die (part no. 90025) trims and chamfers a case mouth in the same operation, mounted right in a reloading press instead of requiring a separate hand-crank trimmer. Because 380 Auto headspaces on the case mouth rather than a rim or shoulder, keeping case length consistent matters more for this cartridge than it does for many others, and this die brings every case to a uniform length without calipers or manual measurement. It threads into a standard press like any other reloading die, and a click-adjustable stop lets the trim length be set in small increments.

Key Specifications

• 380 Auto is the caliber this trim die is machined for.
• Simultaneous trim and chamfer squares the case mouth and deburrs it in one operation.
• Click-adjustable trim length lets you set case length in small, repeatable increments without calipers.
• Standard 7/8-14 die thread means it mounts directly to a standard reloading press.

Frequently Asked Questions

Why does case length matter more for 380 Auto? 380 Auto headspaces on the case mouth, so uniform case length has a more direct effect on chambering and function than it does on rimmed or bottleneck cartridges.

Do I need calipers to use this die? No, the click-adjustable stop sets trim length without measuring each case by hand.

Does this die also chamfer the case mouth? Yes, it trims and chamfers in the same operation.
