Precision tool for measuring overall cartridge length and bullet seating depth with 0.001-inch accuracy. Designed for bolt-action and single-shot rifles with straight-line chamber access. Requires separate modified case.
Hornady Lock-N-Load OAL Gauge: Precision Seating Depth Control
The Lock-N-Load O.A.L. Gauge represents the gold standard for controlling bullet seating depth and optimizing the critical relationship between your bullet and the rifling.
Why Seating Depth Matters
The distance from the tip of your bullet to the rifling—called "jump"—directly affects accuracy and consistency. This gauge allows you to measure and control that distance with precision, resulting in tighter groups and more reliable performance.
Key Features
- Straight-line design for bolt-action rifles, single-shot firearms, and any rifle with direct chamber access
- Accuracy to 0.001 inches for precise, repeatable measurements
- Simple operation requiring only a modified case specific to your caliber
- Durable steel construction built to last through countless reloading sessions
How It Works
Insert a modified case (caliber-specific, sold separately) into your rifle's chamber, then thread it onto the gauge. Slowly close the bolt until it contacts the bullet tip. The gauge displays your overall length measurement, allowing you to seat bullets to the exact depth needed for your rifle's unique chamber.
What You Need to Know
This straight-model gauge requires a Hornady Lock-N-Load Modified Case matched to your specific caliber. Once you have the correct modified case, this tool becomes an essential part of your reloading bench for achieving the precision accuracy modern shooting demands.
