Description
The Hornady Lock-N-Load OAL Gauge Straight is an essential reloading tool that regulates seating depth and controls the critical jump to the rifling, directly improving ammunition accuracy and consistency. This precision instrument allows reloaders to optimize cartridge performance by measuring the exact distance from the bullet tip to the rifling lands in any firearm chamber.
Key Specifications
Designed specifically for bolt-action rifles and single-shot firearms, the Hornady Lock-N-Load OAL Gauge Straight features a straight-line design that provides unobstructed access to the chamber. The gauge integrates seamlessly with Hornady’s Lock-N-Load reloading system, one of the most trusted names in ammunition reloading. This tool requires a Lock-N-Load Modified Case (sold separately) that is custom-fitted to your specific firearm chamber. The modified case threads onto the gauge body, allowing you to measure cartridge seating depth with precision that translates directly to improved shot placement and reduced velocity variation.
Performance & Ballistics
Achieving consistent bullet seating depth is fundamental to producing accurate ammunition. The Hornady Lock-N-Load OAL Gauge Straight eliminates guesswork by providing measurable data on the distance from your bullet’s tip to the rifling lands. This measurement, known as the Cartridge Overall Length (COAL) or jump distance, significantly impacts how ammunition performs downrange. By establishing your optimal seating depth, you minimize pressure variations and velocity spreads, resulting in tighter groupings and more predictable ballistic performance across your shooting sessions.
Intended Use
This Hornady OAL Gauge Straight is purpose-built for reloaders who demand precision and consistency. Whether you’re preparing ammunition for competitive shooting, long-range hunting, or tactical training, controlling jump to the rifling is critical. The straight-line configuration makes it ideal for firearms with direct chamber access, including popular bolt-action hunting rifles, precision tactical rifles, and single-shot handguns. Reloaders who understand that ammunition quality determines firearm performance will appreciate this tool’s accuracy and reliability.
