Primer Pocket Reamers

Why Primer Pocket Reaming Matters

A primer pocket reamer removes military crimps or burrs left inside the primer pocket after firing or factory crimping. This ensures the primer seats flush and evenly, improving ignition consistency and safety during reloading.

No. You only need to ream brass with crimped primer pockets, commonly found in military or NATO-spec ammunition. Once the crimp is removed, the case will not need to be reamed again for future reloads.

Reaming removes material to eliminate crimps or rough edges, while uniforming cuts the pocket to a precise, consistent depth. Both help ensure primers seat evenly, but reaming is typically done on once-fired military brass, whereas uniforming enhances consistency in all brass types.

Yes. Cleaning primer pockets first removes carbon buildup, making reaming smoother and more precise. Use a primer pocket brush or scraper before reaming for best results.

L.E. Wilson Primer Pocket Reamers are designed for manual precision work, but they can also be used with a power adapter for higher-volume brass prep. Always maintain control and moderate speed to avoid removing too much material.

Pair your reamer with Punch and Base Sets for primer removal, and follow up with Case Trimmers and Deburring Tools for complete case prep and uniform performance.
