Hornady Lock-N-Load Modified Case .338 Lapua

Achieve Tack-Driver Accuracy with Precision Seating Depth

The difference between average accuracy and exceptional performance often comes down to a few thousandths of an inch. Controlling the distance between your bullet and the rifling—what shooters call "jump"—is fundamental to consistent, tight groups.

How It Works

The Hornady Lock-N-Load O.A.L. Gauge is the industry standard for measuring this critical dimension with precision. To use it, you need a modified case that matches your firearm's chamber.

Why This Modified Case Matters

Precision Engineering:

• Threaded at the case head for secure attachment to the gauge
• .002" oversized neck accommodates your actual bullets
• Delivers measurements accurate to .001"

Real-World Accuracy: Unlike competitive products that use simulated bullets with arbitrary shapes, this modified case accepts the exact bullets you'll be loading. This means your measurements reflect reality, not approximations. The result is seating depth data you can trust.

The Bottom Line

If you're serious about precision reloading and want to unlock your rifle's true potential, this modified case is an essential tool. It's the foundation of the most reliable method available for establishing optimal bullet-to-rifling relationships.
