The Hornady Lock-N-Load Cartridge Gauge for 6.5mm Creedmoor (.264 diameter) is a simple but essential tool for anyone serious about hand-loading ammunition. Whether you're assembling match-grade rounds for long-range hunting or building precise target loads, this gauge lets you verify that your finished cartridges will chamber reliably in a standard SAAMI chamber. It's the kind of no-nonsense go/no-go check that catches loading errors before they hit your rifle or create safety issues on the range.
Built into Hornady's Lock-N-Load system, this gauge works as a quick quality-control step in your reloading workflow. Load a round, slip it into the gauge, and you'll know immediately whether your case length, bullet seating depth, and overall dimensions are within spec. For 6.5mm Creedmoor shooters—a caliber that rewards precision—this kind of verification is worth its weight in consistency and peace of mind.
The Lock-N-Load design means the gauge integrates with Hornady's modular reloading platform if you're already running that ecosystem, but it functions just fine as a standalone tool on any workbench. Keep one next to your press, use it on every batch, and you'll eliminate guesswork from the loading process.

Frequently Asked Questions
What does a Lock-N-Load cartridge gauge actually do?
It verifies that your loaded cartridges meet SAAMI chamber specifications, ensuring they'll chamber and fire safely in standard 6.5mm Creedmoor rifles. Think of it as a go/no-go check—if the round slots in smoothly, your dimensions are correct; if it doesn't, you've caught an issue before firing.
Can I use this gauge on both hand-loaded and factory ammunition?
Yes, the gauge works on any 6.5mm Creedmoor cartridge, factory or reloaded. It's a useful quality-control tool for verifying that any ammo you're about to fire will chamber properly.
Do I need other Hornady Lock-N-Load equipment to use this gauge?
No. While it integrates with Hornady's Lock-N-Load reloading system, the gauge functions as a standalone tool on any reloading bench.
What happens if a loaded round doesn't fit in the gauge?
It means the cartridge exceeds SAAMI specifications—likely due to case length, bullet seating depth, or overall length being out of spec. You'll need to adjust your dies or check your cases before loading further.
