Lee Precision’s Quick Trim Die for .300 AAC Blackout (brand part no. 90689) is a die body built to work with Lee’s Deluxe Quick Trim Case Trimmer, trimming brass to the correct length while simultaneously chamfering the inside and outside of the case mouth in one motion. No calipers, measurement, or adjustment are required; the reloader simply installs the appropriate quick trim die in the press and starts trimming. That speed is useful on a cartridge like .300 Blackout, which sees heavy volume from AR-platform shooters running both supersonic and subsonic loads. For reloaders standardized on Lee case-prep tools, this reloading die speeds up trimming .300 Blackout brass.
