Hornady
The Hornady Lock-N-Load Modified Case for .338 ARC is a precision reloading accessory engineered to work with Hornady's Lock-N-Load Precision gauge system. If you're serious about handload development, case inspection, or verifying headspace and overall length, this modified case serves as a go-gauge reference that integrates seamlessly with your gauging setup. The fine-thread attachment system locks the case square to the gauge body, eliminating alignment guesswork and ensuring repeatable, accurate measurements shot after shot.
What makes this case special is its geometry. The neck has been opened and rounded to a precise diameter, allowing standard bullets to slide into the case mouth concentrically—without binding or wobbling. This concentricity matters when you're sorting brass, checking neck runout, or developing loads for precision rifle shooting. Whether you're prepping ammo for a match rifle, a long-range hunter, or just want to catch headspace issues before they hit the range, having a properly dimensioned modified case in your reloading bench saves time and prevents costly mistakes.
The .338 ARC is gaining traction as an effective mid-range hunting and target cartridge, and having a dedicated modified case for your gauging system keeps your process dialed in. This is a bench tool, not a loaded round—use it in conjunction with your Hornady Lock-N-Load gauges to verify case dimensions and firearm headspace with confidence.
| Cartridge | .338 ARC |
| Brand | Hornady |
| System Compatibility | Lock-N-Load Precision gauges |
| Type | Modified case for gauging |
The Hornady Lock-N-Load Modified Case is designed specifically for use with Hornady Lock-N-Load Precision gauge systems. The fine-thread attachment secures it directly to compatible gauges in the series.
No, this is a precision reloading reference tool, not a live cartridge. It's used on your reloading bench to verify case dimensions, headspace, and overall length using your Hornady gauges.
The package includes the modified case only. Dial calipers and OAL gauges are sold separately and are not included.
The neck is intentionally modified—opened and rounded to a precise diameter so that a standard bullet can fit into the case mouth concentrically without binding. This ensures accurate, repeatable gauging and inspection.
