Hornady Lock-N-Load Modified A Case .22 ARC

Precision Reloading Measurement Made Simple

The Hornady Lock-N-Load Modified A Case for .22 ARC is an essential accessory for serious handloaders who demand accuracy. This specially prepared brass case is designed to work with the Hornady Lock-N-Load O.A.L. Gauge—a tool that measures overall cartridge length with extraordinary precision.

How It Works

Unlike competitive gauges that rely on simulated bullets with arbitrary shapes, the Hornady system uses your actual bullets for measurement. The modified case features:

• Threaded case-head for secure attachment to the gauge
• .002" oversized neck that accepts the exact bullets you intend to load
• Precision engineering that delivers measurements accurate to .001"

Why This Matters

Overall length is critical to safe, accurate handloading. Using your actual bullets—not approximations—ensures your measurements are true to your specific ammunition setup. This level of precision is impossible to achieve with generic gauges that use dummy rounds.

What You Get

One modified .22 ARC case, ready to thread onto your Lock-N-Load O.A.L. Gauge. This is a consumable accessory; you may want to keep spares on hand as you develop loads for different bullet styles and weights.

For the serious reloader, this is the foundation of consistent, safe ammunition.
