Lee Precision Case Length Gage and Shellholder 6.5 Creedmoor 90814
The Case Length Gage and Shellholder is the assembly consisting of the length gauge and the dedicated shellholder with which Lee Precision trims cases to length and squares the mouth. This unit works on the 6.5 Creedmoor: the trim length is determined by the gauge geometry, so it does not depend on adjustments or operator readings and remains identical across the entire batch of cases.
The case is held by the shellholder while the cutting tool rests on the gauge: the cut stops automatically when the case reaches the specified length. The assembly acts as a go/no-go gauge: if the case is not cut, it means it is already within limits. Lee states a tolerance of +.000/-.015 inches for these units. Trimming occurs after full-length resizing, once the case has stretched: returning it to size prevents the mouth from bumping against the chamber and maintains a constant crimp. The mouth results perpendicular to the case axis, a condition that affects bullet concentricity. The system is entirely mechanical and requires no calibration or maintenance.
