The Hornady B30N Lock-N-Load Modified Case is a specialized reloading tool designed for handloaders working with 30 Nosler brass. This modified case is engineered to pair with Hornady's Lock-N-Load Precision gauges, giving you the accuracy control serious precision shooters and competitive reloaders demand. Whether you're developing loads for long-range hunting or match shooting, this tool helps you achieve the concentricity and case alignment that separate tight groups from scattered shots.
The B30N uses a fine-thread connection system to attach securely to your Lock-N-Load gauge, keeping the case perfectly square and consistently oriented for reliable chamber alignment checks. The case neck is precisely rounded and opened to a standard diameter, allowing bullets to seat smoothly while maintaining concentric orientation—critical for eliminating runout that can degrade accuracy. This level of control over case prep is what separates hand-assembled match ammo from run-of-the-mill loads.
If you're already invested in Hornady's Lock-N-Load gauge system, adding the 30 Nosler modified case opens up this cartridge to your setup. For reloaders committed to squeezing every bit of precision from their ammunition, this is a straightforward upgrade that addresses one of the most controllable variables in the reloading process.
The B30N is designed to work with Hornady's Lock-N-Load Precision gauges. The fine-thread connection system is specific to that gauge family.
No. The B30N is specifically engineered for Lock-N-Load Precision gauge systems and is not compatible with standard reloading presses or other gauge brands.
A modified case allows you to check case alignment and concentricity in your gauge with the same precision you'd get in your actual firearm chamber. The rounded neck and precise opening ensure bullets seat concentrically, which reduces runout and improves accuracy potential.
Concentricity—keeping the bullet aligned with the case axis—minimizes runout and helps ensure consistent, predictable chamber fit and bullet release. This is especially important for precision rifle and competitive shooting where small variables compound downrange.
