This case trimmer has all the same great features as the standard Redding Trimmer with the addition of a case length micrometer and push button chuck lock. The 2400 trimmer also utilizes a new extended cast iron frame which enables it to handle the lastest long action cartridges and longer old time classic as well. Trims cases up to three and one fourth in length. The micrometer is easy to read and makes quick and precise case length adjustments in increments of .001 inch. Redding's push button chuck lock simplifies case loading and unloading and faciliates perfect alignment of the case between the collet and pilot. Includes six case pilots - .22 cal, 6mm, .25 cal, .270 cal, 7mm, Mfg: Redding
