The Deluxe Quick Trim Case Trimmer quickly and precisely trims your brass to the correct length at the same time it chamfers the inside and outside of the case mouth. No calipers, measurement or adjustment required. Simply install the appropriate quick trim die in your press and start trimming. A click adjustable stop allows trim length adjustment in .001 of an inch increments. It allows the user to shorten case to a uniform shorter length than standard, reducing trimming frequency. Included is a snap on the chip catcher.
