Hornady Lock-n-Load Attachment Adapter

The Hornady Lock-n-Load Attachment Adapter is a motorized case preparation accessory engineered to integrate with standard power drills, enabling efficient batch processing of fired brass during the ammunition reloading workflow. This adapter transforms a cordless drill into a precision case prep station, significantly reducing the manual labor required for depriming, cleaning, and primer pocket uniforming operations.

The adapter's compact design measures 4.75 inches in length with a lightweight footprint of just 0.04 lbs, making it portable and easy to store alongside other reloading equipment. Its quick-change interface is compatible with Hornady Lock-n-Load reloading systems, a modular platform widely adopted among handloaders for its tool-less cartridge case holder and accessory switching capability. The motor power delivered by a standard variable-speed drill—typically 12 to 18 volts—provides sufficient rotational force for case processing tasks without imposing excessive stress on fired brass.

This accessory is designed for reloaders who process moderate to large volumes of fired ammunition and seek to streamline their case prep phase. Whether preparing rifle or pistol brass, the motorized approach eliminates repetitive hand-cranking, reducing fatigue during extended reloading sessions. The adapter integrates seamlessly with Hornady's modular case prep center tools and collet systems, allowing shooters to switch between depriming dies, cleaning tools, and other case conditioning equipment without disassembly. Best results are achieved with a drill featuring consistent speed control, enabling operators to match rotational velocity to the specific prep task at hand.
