Lee Quick Trim Die 300 Win Mag

The Lee Quick Trim Die is a reloading accessory designed to bring fired brass back to SAAMI-spec length in a single pass. Caliber-specific to 300 Winchester Magnum, this single steel die body installs in Lee's Deluxe Quick Trim Case Trimmer to chamfer and trim the brass to the correct overall length - no calipers or measurement required.

Built on a standard 7/8x14 die body, the Quick Trim die threads directly into the case trimmer and uses Lee's cutter and chamfer tools to deburr the case mouth while it trims. Consistent case length supports reliable feeding, proper chambering, and accurate bullet seating through the rest of the reloading process. Steel construction keeps the die dimensionally stable through repeated use, and the design requires no shell holder cap, making case prep a fast, repeatable step.

From processing range brass to prepping fresh hunting loads, this 300 Win Mag Quick Trim die streamlines rifle case prep into one quick, reliable operation.
