The Hornady Lock-N-Load Modified Case (Hornady part no. A264) is chambered for 264 Winchester Magnum and built to work with the Hornady Lock-N-Load O.A.L. Gauge. Regulating seating depth, and the resulting jump to the rifling, is widely regarded as fundamental to improved accuracy, and a few thousandths of an inch of change between the bullet and the rifling can be the difference between average groups and a real tack-driver. This modified case threads onto the O.A.L. Gauge so you can measure the exact distance from the case head to where your specific bullet contacts the lands in your own rifle. It is a small, purpose-built tool that precision reloaders treat as essential for dialing in seating depth.

Key Specifications
