Lee 90088 Quick Trim Pistol Die 357 Mag

The Lee 90088 Quick Trim Die is a dedicated case trimming die for the .357 Magnum, designed as the caliber-specific die body for Lee's Deluxe Quick Trim Case Trimmer (sold separately). Once installed in the Quick Trim tool, fired cases are trimmed to the correct overall length and have the inside case mouth chamfered in a single, repeatable operation - no separate prep station required.

The die is cut to Lee's standard 7/8"x14 thread and requires a shellholder matched to the .357 Magnum case head (sold separately). There is no need for calipers, measurement, or adjustment - the die is factory-set to the correct trim length for the cartridge, so the reloader simply runs cases through the tool to keep revolver brass within spec. That makes it one of the fastest, most repeatable ways to control case length on a high-volume handgun loading bench.

Sold as a single die body, the 90088 ships in a plastic storage box to keep the cutting surfaces and threads protected between reloading sessions. It is intended for handloaders who already run a Lee Quick Trim system and need a dedicated die for their .357 Magnum brass. The die body alone is what is included here; the Quick Trim case trimmer base and shellholder are sold separately.
