Hornady
The Hornady Lock-N-Load Modified Case "C" Series .338 Lapua is a precision reloading accessory designed to help you dial in your cartridge's exact overall length (O.A.L.) to your rifle's chamber. If you're serious about handloading for accuracy, controlling the distance between your bullet's tip and the rifle's rifling—often called "jump"—is where the real precision work begins. A few thousandths of an inch can shift a group from decent to genuinely tack-driving, and this modified case lets you measure that relationship with .001" accuracy.
The modified case threads onto Hornady's Lock-N-Load O.A.L. Gauge and is sized to your .338 Lapua chamber. Unlike gauges that use a generic dummy bullet, this case accepts the exact bullets you plan to load, so your measurement reflects the real relationship between your specific projectile and your specific rifle's throat. The case features a threaded case-head and a .002" oversized neck to grip your chosen bullets securely during measurement—eliminating guesswork and the inaccuracy that comes with simulated alternatives.
This tool works hand-in-hand with the Lock-N-Load O.A.L. Gauge (sold separately) and is essential if you want repeatable, verifiable data for your .338 Lapua loads. Whether you're fine-tuning a long-range hunting load or working up precision match ammunition, knowing your true O.A.L. to within a thousandth of an inch removes one major variable from the accuracy equation.
| Caliber | .338 Lapua |
| Type | Modified Case for Lock-N-Load O.A.L. Gauge |
| Neck Sizing | .002" oversized |
| Measurement Accuracy | .001" |
| Manufacturer | Hornady |
This modified case threads onto the Hornady Lock-N-Load O.A.L. Gauge and allows you to measure the exact overall length of your cartridge in your specific rifle's chamber. It helps you determine the proper seating depth and bullet-to-rifling jump for your .338 Lapua loads.
Yes, this modified case is designed as a component of the Lock-N-Load O.A.L. Gauge system and requires the gauge body to function.
This case is sized to work with standard .338 Lapua chambers. Fit may vary slightly between rifles due to chamber tolerances, but it is designed for typical .338 Lapua specifications.
The oversized neck is designed to accept the actual bullets you intend to load. For the most accurate measurement, use the same bullet profile and weight you plan to use in your finished ammunition.
