Lee 90088 Quick Trim Case Trimmer Die for .357 Magnum

The Lee 90088 Quick Trim Die is designed for use with Lee’s Deluxe Quick Trim Case Trimmer to help reloaders trim .357 Magnum brass quickly, consistently, and accurately. This case trim die supports a streamlined trimming process by guiding the case while the trimmer brings the case mouth to the correct length. It is an efficient addition to a reloading setup for users who want repeatable case preparation without relying on separate measuring steps for every case.

Simply install the Lee Quick Trim Die in a compatible reloading press and begin trimming. The system is designed to trim the case while simultaneously chamfering both the inside and outside of the case mouth. This combined operation helps prepare brass for smoother bullet seating and easier case handling, while reducing the need for additional manual preparation after trimming. No calipers, measurement, or adjustment are required during the normal Quick Trim process, helping make case preparation more straightforward and consistent.

Built for .357 Magnum applications, the Lee 90088 is part of the Quick Trim die series and is supplied as a single case trim die. It is intended for reloaders who value a repeatable workflow and clean, properly prepared case mouths. Use this die with the appropriate Lee Deluxe Quick Trim Case Trimmer and compatible press equipment. As with all reloading components, follow the manufacturer’s instructions and use safe, established reloading practices when preparing brass.
