Tools guide the cutter over the sized cartridge case neck and are supported by the special pilot/reamer (pilots/reamers sold separately)
The inside and outside of the neck are turned simultaneously
The Auto Feed Attachment (for Case Trimmer—2 and Trim Pro® Manual Case Trimmer) advances the cutting tool evenly over the case neck with each turn of the trimmer handle
This kit combines the trim pro case trimmer and our dial caliper to get you on your way to trimming brass down to SAAMI specs
Having cases the same length guarantees more consistent crimps, smaller standard deviation and extreme spread of ammunition velocities, and helps ensure proper chambering of your ammunition
