Overview
This tool is intended for rifle brass preparation when consistent primer seating matters. It cuts primer pockets to SAAMI depth specifications, removes built-up carbon residue from previous firings, and squares the bottom of the pocket relative to the case head. A preset stop collar set to SAAMI specifications helps keep the process controlled and repeatable. It is not intended for pistol brass, where the pocket would be cut too deep.

Considerations & Trade-offs
- This tool is limited to rifle brass; using it on pistol brass will cut the pocket too deep.
- It is designed to uniform primer pockets to SAAMI depth, so it is a brass-prep step rather than a general-purpose cleaning tool.
- The preset stop collar is set to SAAMI specifications, which means it leaves little room for adjusting depth beyond that standard.
- Its value is most relevant for reloaders who want consistent primer pocket depth; it may be unnecessary for brass that does not need this level of preparation.
