Hornady 380711 Lock-N-Load Cartridge Gauge 270Win Silver
$22.05
The Hornady Lock-N-Load Cartridge Gauge for .270 Winchester is a straightforward quality-control tool every handloader should keep in their die box. Before you load rounds, fire them downrange, or sell ammunition, this go/no-go gauge verifies that your brass and finished cartridges will chamber safely in a standard SAAMI .270 Win chamber. It's easy insurance against the frustration of loads that bind or won't seat, and it takes seconds to use.
Handloaders often focus on powder charge and bullet seating, but case dimensions and overall cartridge length matter just as much. This gauge catches problems early—whether a case has been repeatedly fired and stretched, a round is loaded too long, or something else went wrong during prep or assembly. Running your rounds through the gauge before range day or before boxing them up means you're confident in every shot you fire.
The silver finish gauge is built to Hornady's reputation for precision reloading tools. It's quick to check a batch of ammo and compact enough to live permanently on your bench or in a range bag. For handloaders working in .270 Win—whether you're building for hunting rifle accuracy or consistency at the long-range target line—this is a low-cost layer of quality control that pays for itself the first time it catches an out-of-spec round.

Frequently Asked Questions
Why would I need a cartridge gauge for my reloading setup?
A cartridge gauge is your first line of defense against loading mistakes or case issues. It confirms that each finished round will actually chamber in your rifle before you take it to the range. Catches out-of-spec loads before they become range frustration or, worse, a safety problem.
What does "go/no-go" mean?
The gauge has two contact surfaces that mimic a standard SAAMI .270 Win chamber. A properly loaded round should fit through the "go" side easily. If it doesn't, or if it forces into the "no-go" side, that round doesn't meet spec and shouldn't be fired in a standard chamber.
Can I use this gauge with factory ammunition too?
Yes. Many reloaders also use cartridge gauges to spot-check factory ammo or ammunition from other sources, though factory rounds are already vetted. The gauge works the same way regardless of source.
Do I need a separate gauge for each caliber?
Yes. This gauge is caliber-specific to .270 Winchester. If you reload other calibers, you'll need a separate gauge for each one.
