Hornady Lock-N-Load Overall Length Gauge Straight

The Hornady Lock-N-Load C1000 Straight O.A.L. Gauge is universally acclaimed as the most accurate, easy-to-use, and reliable method of regulating bullet seating depth and the resulting jump to the rifling during the reloading process. This straight OAL gauge works for all bolt-action and single-shot firearms, or any firearm with straight-line access to the chamber. The straight model is preferred by handloaders because it is the most precise and user-friendly configuration available.

Built around a precision-machined steel working body housed in a durable anodized red aluminum shell, the C1000 delivers repeatable measurements to 0.001 inch accuracy. The gauge pairs with Hornady's Lock-N-Load Modified Cases (sold separately by caliber), which replicate your specific chamber dimensions so the bullet is seated exactly where it will be when fired. Combined with a quality set of calipers, the C1000 gives reloaders a rifle-specific baseline that translates directly into tighter groups and more consistent velocities downrange.

As a multi-caliber tool, a single C1000 covers every chamber you reload for - simply swap in the modified case for the cartridge you're loading. From precision hunting rifles to match-grade benchrest builds, the Hornady Lock-N-Load Straight O.A.L. Gauge is foundational reloading equipment for any serious handloader.

Note: A caliber-specific modified case is required for use and is not included with this gauge.
