Hornady A223 Lock-N-Load Modified Case 223 Remington Rifle Brass

The Hornady A223 Lock-N-Load Modified Case transforms precision reloading by providing exact chamber measurements for the 223 Remington cartridge. This specialized brass case integrates seamlessly with Hornady's Lock-N-Load Overall Length Gauge system to determine optimal bullet seating depth. Reloaders achieve consistent cartridge overall length measurements that match their specific rifle's chamber dimensions.

What Makes This Different

Unlike standard fired cases that may have expanded unevenly, this modified case features a precisely machined neck that accepts the Lock-N-Load system's measuring rod. The case maintains consistent dimensions across multiple measurements, eliminating variables that affect accuracy in traditional methods. Standard measuring techniques often produce inconsistent results due to case neck variations and extraction marks.

Key Features

• Precision-machined neck accepts Lock-N-Load measuring system components
• 223 Remington chamber specification ensures proper fit in bolt-action and semi-automatic rifles
• Consistent case dimensions eliminate measurement variables between sessions
• Durable brass construction withstands repeated measuring cycles
• Compatible with all Lock-N-Load Overall Length Gauge systems
• Allows measurement of multiple bullet weights and profiles
• Eliminates guesswork in determining optimal cartridge length

Precision rifle shooters rely on this modified case to establish exact bullet seating depths that maximize accuracy potential. Competition reloaders use the consistent measurements to develop loads that perform identically across different rifles chambered in 223 Remington. The system proves particularly valuable for AR-15 platform rifles where magazine length constraints require precise cartridge dimensions. Varmint hunters benefit from the improved accuracy that comes with optimized bullet positioning relative to the rifle's lands.

Technical Specs

• Caliber: 223 Remington
• Case material: Brass
• Modified neck diameter: Precision-machined to specification
• Overall case length: 1.760 inches (standard 223 Rem specification)
• Compatible with: All Hornady Lock-N-Load Overall Length Gauges
• Thread specification: Standard Lock-N-Load system threading
• Country of origin: United States

This modified case eliminates the trial-and-error approach to determining optimal cartridge length. Reloaders who demand consistent results across different bullet types will find this tool essential for developing accurate ammunition. The investment pays dividends through improved accuracy and reduced load development time.
