Hornady Lock-N-Load O.A.L. Gauge Straight, Part C1000

The Hornady Lock-N-Load O.A.L. Gauge, Part C1000, provides a precise and reliable way to regulate cartridge seating depth and evaluate bullet jump to the rifling. Designed for multi-caliber use, this straight overall length gauge helps reloaders establish a consistent relationship between the bullet ogive and the rifle’s lands, supporting accurate load development and repeatable ammunition setup.
The straight gauge design is intended for bolt-action and single-shot rifles, as well as other firearms that provide straight-line access to the chamber. Its steel construction offers dependable service for routine reloading work, while the straightforward operating design makes it easy to use when checking chamber-specific seating requirements. By measuring seating depth in the firearm where the ammunition will be used, reloaders can make informed adjustments rather than relying solely on generic overall cartridge length data.
A modified case matched to the firearm’s chamber is required for use and is not included with this gauge. Select the appropriate Hornady modified case separately, install the bullet to be evaluated, and use the gauge to determine the desired seating position. The Hornady Lock-N-Load O.A.L. Gauge is a practical addition to a reloading bench for users seeking greater control over bullet seating depth, chamber fit, and load consistency. Its universal multi-caliber capability and compatibility with a broad range of bolt-action and single-shot rifles make it a useful tool for precision-oriented handloading.
