Lyman Cal. 223 Cartridge Case Gauge
For precision reloaders working with the versatile .223 Remington cartridge, maintaining exacting standards in case preparation is paramount to achieving consistent accuracy and reliable performance. The Lyman .223 Remington Case Length and Headspace Gauge provides a critical quality control step by allowing you to quickly and accurately verify whether your brass cases fall within the stringent dimensional tolerances required before reloading. This ensures every round you assemble is safe to fire, performs consistently, and maximizes ballistic efficiency.
Constructed from a solid block of high-grade 6061 T6 anodized aluminum and precision-machined using advanced CNC technology, this gauge is engineered to meet or exceed the SAAMI minimum specifications for the .223 Remington cartridge. Its robust design makes it an indispensable tool for identifying cases that have stretched beyond safe limits, exhibit deformation, or have improper headspace dimensionsfactors that can lead to dangerous pressure spikes, case head separations, or accelerated firearm wear.
Key Measurement Functions
- Overall Case Length Verification: Ensures that cases are trimmed to the correct length, preventing excessive pressures caused by over-length brass and maintaining consistent bullet seating depth.
- Headspace Assessment: Confirms that the case head seats properly against the chamber shoulder, guaranteeing safe and reliable cartridge chambering and extraction.
Advantages of the Lyman .223 Remington Gauge
- Precision Calibration: Specifically designed for .223 Remington dimensions, with compatibility for 5.56 NATO cases when reloading under controlled conditions.
- User-Friendly Operation: Simply insert the case into the gauge cavity and observe whether it sits flush with the reference surfaceno protrusion or recess indicates compliance.
- Durable Construction: Built to withstand the rigors of high-volume reloaders and tactical operators requiring dependable, repeatable measurements.
- Error Prevention: Detects out-of-spec cases before powder charging or bullet seating, reducing the risk of catastrophic failures and improving overall ammunition quality.
Step-by-Step Usage Instructions
- Place the gauge on a stable, flat surface to ensure accurate measurement.
- Insert the .223 Remington brass case into the designated caliber cavity.
- Check the case alignment: the case mouth should be perfectly flush with the top edge of the gauge. Any case that protrudes above or sits below this reference plane is outside acceptable tolerances and should be trimmed or discarded.
