Precision aluminum gauge verifies ammunition quality and consistency against SAAMI minimum chamber tolerances. Drop-in test ensures your rounds will chamber reliably.
The Lyman Ammo Checker is a straightforward quality control tool that every reloader and ammunition-conscious shooter should keep on the bench. This solid aluminum gauge is machined to exacting SAAMI minimum chamber specifications, giving you a reliable way to verify that both your handloads and factory ammunition will chamber properly in your firearm.
The concept is elegantly simple: drop your cartridge into the gauge. If it fits, it will chamber in your gun. If it doesn't, you've caught a potential problem before it reaches your chamber.
Consistency is the foundation of reliable shooting. Whether you're a dedicated reloader fine-tuning your loads or a shooter who wants to verify factory ammunition, this gauge provides objective confirmation that your rounds meet chamber specifications. It's an inexpensive insurance policy against the frustration of ammunition that won't chamber or the safety concerns of out-of-spec rounds.
The Ammo Checker has become a trusted standard among serious reloaders since its introduction, and for good reason: it works.
