300 Blackout Cut off Trimming Jig Auto-Ejecting Brass Case Trimmer

Great quality and design. Can trim 100 brass cases in minutes.

Makes a good size to form and trim to a perfect size to reload. Easy installation on the mini chop saw from Harbor Freight.

The detent ball under spring tension of any kind which is mandatory for the depth setting to work properly causes the case to be caulked sideways.
