Lyman Ammo Checker™ Single Caliber Ammunition Gauge

For reloaders demanding uncompromising reliability and stringent quality control in their metallic and semi-metallic cartridge assemblies, the Lyman Ammo Checker™ Single Caliber stands as an essential precision inspection tool. Engineered specifically for ballistic professionals and avid handloaders, this gauge enables you to verify that each round conforms exactly to SAAMI dimensional specifications prior to chambering and firing, ensuring optimal feeding, chambering, and ballistic performance.

Precision-Engineered Design for Absolute Dimensional Verification

Constructed from high-grade anodized aluminum alloy with CNC machining tolerances held to exacting SAAMI standards, the Lyman Ammo Checker™ provides a robust and stable platform for dimensional inspection. Its solid block configuration offers exceptional durability and tactile feedback, allowing the user to quickly assess cartridge overall length (COL), case headspace, and neck dimensions with professional-grade accuracy.

By inserting your reloaded or factory ammunition into the gauge’s precisely bored cavity, you can immediately determine if the cartridge meets the critical length and diameter parameters necessary for reliable chambering and extraction. A smooth, flush fit indicates compliance, while any protrusion or resistance signals the need for neck sizing, trimming, or case length adjustments before live fire.

Key Advantages of Utilizing the Lyman Ammo Checker™

• Enhanced Safety: Detects dimensional anomalies that could cause misfeeds, stovepipes, or primer ignition failures, reducing the risk of firearm malfunctions.
• Consistent Accuracy: Guarantees uniform cartridge dimensions, promoting consistent chamber pressures and ballistic trajectories for precision shooting.
• Efficient Workflow: Enables rapid inspection of large batches of handloads without the need for micrometers or calipers, streamlining your reloading bench operations.
• Wide Caliber Compatibility: Available in an extensive range of calibers from .380 ACP through 7.62x39mm, accommodating both pistol and rifle cartridges commonly used in metallic and semi-metallic reloads.

Operational Procedure for Optimal Cartridge Verification

1. Place the Ammo Checker on a stable, flat surface to ensure accurate seating.
2. Slowly insert the reloaded cartridge into the gauge’s caliber-specific cavity, avoiding excessive force that could damage the case or gauge.
3. Confirm that the cartridge seats fully and aligns flush with the top edge of the gauge, indicating proper overall length and case dimensions.
4. If the cartridge fails to seat correctly or protrudes beyond the gauge surface, inspect the case neck tension, base dimensions, and trim length. Perform necessary adjustments such as neck sizing, trimming, or resizing before proceeding to live fire.

An Indispensable Tool for Your Reloading Bench

The Lyman Ammo Checker™ Single Caliber Gauge is a critical component for reloaders who prioritize precision, safety, and ballistic consistency in every round produced. Its straightforward design belies its profound impact on quality assurance, providing reloaders with the confidence that each cartridge will chamber flawlessly and perform reliably under firing conditions.

Do not compromise on your shooting safety or accuracy. Integrate the Lyman Ammo Checker™ into your reloading toolkit to elevate your quality control protocols and ensure your handloads meet the highest standards of dimensional integrity and functional reliability.
