The Hornady Lock-N-Load Cartridge Gauge for .308 Winchester is a straightforward verification tool that belongs in any serious reloader's toolkit. Whether you're working up loads for precision rifle competition, hunting, or long-range practice, this gauge lets you confirm that your finished ammunition will chamber cleanly in a SAAMI-spec rifle. It's a simple but critical checkpoint: you can load everything perfectly, but if the cartridge won't fit the chamber, you've got a problem. This gauge catches that before you ever reach the range.
The Lock-N-Load design makes the check quick and repeatable. Rather than trial-and-error chamber fitting or guesswork, you simply insert your loaded round or fired case and verify fit against the gauge's SAAMI-compliant profile. Reloaders who pay attention to this detail—especially those pushing velocity or experimenting with new brass sources—catch dimensional creep or case stretch before it becomes a safety or reliability issue.
If you're consolidating .308 Winchester brass from different sources, fireforming new cases, or just want confirmation that your loads are within spec, this gauge delivers that confidence for a few dollars. It's not fancy, but it works. Think of it as the quality-control step you run on your own ammo before you trust it downrange.

The Hornady Lock-N-Load Cartridge Gauge verifies that your finished .308 Winchester cartridge—or a fired case you plan to reload—will chamber properly in a SAAMI-spec rifle. It's a physical go/no-go test of overall fit and headspace compliance.
Yes. You can check fired cases (to monitor for stretch or dimensional issues) and loaded cartridges (to verify they're within spec before you shoot them) with the same gauge.
The gauge is part of the Hornady Lock-N-Load system and integrates with other Lock-N-Load reloading tools, though it also functions as a standalone verification tool.
The product is the cartridge gauge itself; specific contents or accessories are not detailed in the available specifications. Contact us directly if you need details on what ships with your order.
