After a case has been reloaded a few times it will stretch beyond maximum length and must be trimmed.
Check and trim cases using the Lee Cutter and Lock Stud in combination with the Lee Case Length Gauge and Shell Holder.
The piloted cutter assures the case mouths are absolutely square and true to the case neck. The fixed length design assures it will never go out of adjustment.

You can trim cases by hand, with an electric drill or the Lee Zip Trim.
The Large Cutter and Lock Stud is designes for use on brass of .475 caliber and larger. Can also be used with all case diameters smaller then .475.
