300 AAC Lyman Cartridge Case Gauge

7832338

In a demanding caliber such as the .300 AAC Blackout, the precision of every cartridge case is paramount to achieving safe, reliable, and consistent metallic and semimetallic reloading results. The Lyman .300 AAC Blackout Case Length and Headspace Gauge is expertly engineered to rapidly and accurately measure two critical parameters: the overall case length and the headspace dimension, ensuring optimal chamber fit and performance.

Constructed from high-grade 6061 T6 anodized aluminum, this gauge offers an exceptional balance of durability and lightweight handling. Precision CNC machining with ultra-tight tolerances faithfully replicates the SAAMI minimum specifications, guaranteeing that any case passing through this gauge meets or exceeds industry standards, making it ready for the shooting bench or field deployment.

Key Functional Verifications:

  • Case Length Measurement: Prevents hazardous overpressure conditions caused by excessively long cases that can disrupt chamber sealing and bullet seating depth.
  • Headspace Assessment: Confirms that the case head aligns perfectly with the chamber shoulder, critical for reliable ignition and consistent ballistic performance.

Advantages for the .300 AAC Blackout Reloading Specialist

  • Caliber-Specific Design: Eliminates cross-caliber confusion, ensuring precise measurements tailored exclusively for .300 AAC Blackout cases.
  • Robust Construction: CNC-machined from a solid aluminum billet block, providing years of accurate service under rigorous reloading shop conditions.
  • User-Friendly Operation: Instantaneous verification by simply inserting the case into the gauge cavity, streamlining the quality control process.
  • Optimized for Both Subsonic and Supersonic Loads: Maintains safe headspace and case length parameters across diverse ballistic profiles, enhancing overall ammunition reliability.

Step-by-Step Usage Instructions

  1. Place the gauge on a stable, flat surface to ensure accurate readings.
  2. Insert the .300 AAC Blackout case fully into the designated cavity of the gauge.
  3. Observe the case positioning: it must sit flush with the gauge surface. Any protrusion or recess indicates the case is out of SAAMI specification and requires trimming or rejection.
