Lyman Handgun Cartridge Checker

The Lyman Ammo Checker™ Handgun Gauge is an indispensable precision tool engineered for handgun and revolver enthusiasts who demand the highest levels of accuracy, safety, and reliability when working with both handloaded and factory ammunition. This expertly crafted gauge facilitates rapid verification of cartridge fit within the chamber, ensuring optimal feeding and function while effectively preventing malfunctions such as stovepipes, failures to feed, or jams during semi-automatic cycling.

Constructed from a solid billet of 6061 T6 aerospace-grade aluminum, the Lyman Ammo Checker™ is CNC-machined with custom tooling adhering strictly to SAAMI minimum dimensional standards. This guarantees a professional-grade evaluation of cartridge dimensions and chamber compatibility. Its vibrant anodized orange finish not only enhances corrosion resistance and surface durability but also ensures high visibility on any reloading bench or range setup, minimizing the risk of misplacement during critical loading sessions.

Compatible Calibers

This versatile multicaliber gauge is meticulously designed to accommodate the most popular pistol and revolver cartridges used in metallic and semi-metallic reloading applications, including:

• .380 ACP (Automatic Colt Pistol)
• 9mm Luger (9x19mm Parabellum)
• .38 Super
• .40 S&W (Smith & Wesson)
• .45 ACP
• .38 Special / .357 Magnum

Key Advantages

• All-in-One Design: Integrates multiple caliber chambers into a single, compact gauge, streamlining the verification process for handloaders and professional reloaders alike.
• Fast and User-Friendly: Simply insert the cartridge into the corresponding chamber; if it seats flush with the gauge surface, the round is within acceptable dimensional tolerances and ready for safe use.
• Failure Prevention: Significantly reduces the likelihood of feeding issues and malfunctions in semi-automatic pistols by confirming proper cartridge overall length and case dimensions prior to loading.
• Optimized for Reloading and Factory Ammo: Whether you are assembling custom loads or verifying commercial factory rounds, this gauge ensures consistent chambering and reliable cycling.

How to Use the Lyman Ammo Checker™

1. Place the gauge securely on a stable, flat surface to ensure accurate measurement.
2. Insert the loaded cartridge into the cavity corresponding to its caliber.
3. If the cartridge seats easily and aligns flush with the top edge of the gauge, it meets SAAMI specifications and is ready for use.
4. If the cartridge protrudes above or fails to fully seat, it indicates dimensional discrepancies requiring adjustment before firing.
