Overview
This case length gauge is designed to help you trim 10mm Auto brass to a consistent length while squaring the case mouth. It works with the Cutter and Lock Stud or Zip Trim, making it a straightforward bench tool for reloaders who want a simple setup for case preparation. The threaded shell holder locks the case down during trimming, and the gauge is intended for cases trimmed to .982 to .992 inches. For handloaders focused on repeatable brass prep, it offers a compact, purpose-built solution without extra complexity.

Considerations & Trade-offs
- Designed specifically for 10MM AUTO cases, so it is not a universal trimming solution for other calibers.
- Requires use with the Cutter and Lock Stud or Zip Trim, so it is only one part of a complete trimming setup.
- The gauge sets trim length to .982 to .992 inches, which is a defined range rather than an adjustable length setting.
- This is a case length gauge and holder, not a full trimming tool by itself.
